Privacy Policy
All iPhone apps by Nattapon Kittisuphat · Last updated: October 27, 2026
The short version: none of our apps needs an account. What you create stays on your iPhone. Free apps may show ads and send anonymous usage counts. Paid apps collect nothing at all. Find your app below for exactly what it does.
This policy covers every iPhone and iPad app published on the Apple App Store by Nattapon Kittisuphat (“we”, “us”), including the apps listed here and any app of ours that is not yet listed. The DozeClock website has its own website privacy page.

An app can appear on the App Store under a slightly different name from the one used here (for example after a store-listing update). The bundle ID shown for each app never changes.
1. What is true for every app
- No account. You never sign up. We do not keep a user database and we do not sell personal information.
- Your content stays with you. What you create or enter is stored on your iPhone (and in your own private iCloud, where an app offers it and you use iCloud). Deleting the app deletes it from the phone.
- Purchases are handled by Apple. We never see your card number or Apple Account.
- Special access (camera, microphone, location, photos, contacts, calendar, Health) is asked for by iOS the first time it is needed, and you can turn it off at any time in iOS Settings.
- No tracking without your permission. If you choose “Ask App Not to Track”, our apps cannot read your advertising identifier (IDFA) and do not track you. We never sell app data, share it with data brokers, or combine it with other companies’ data for advertising.
- This page and the terms page set no cookies and run no analytics or tracking scripts.
- Children. Our apps are not directed at children under 13 and we do not knowingly collect information from them.
2. App by app at a glance
“Ads” = Google AdMob ads in the free version (not shown to people who bought the ad-free unlock, where an app offers one). “Usage counts” = anonymous events sent to Mixpanel.
3. Services we use
Advertising (Google AdMob)
Free apps may show ads served by Google AdMob. Google receives device and advertising data to show and measure ads; it never receives what you create in the app. In the EU, UK and Switzerland, an app either shows Google’s consent form before any ad loads (you can change that choice later under the app’s Settings → ad privacy options), or, if it does not ask, Google serves only limited ads with no personalisation and no device identifiers. Each app’s section says which.
On first launch iOS asks whether the app may track you across other companies’ apps and websites. If you allow it, AdMob may use your device’s advertising identifier (IDFA) for more relevant ads; if you ask the app not to track, ads are less personalised and the app works the same. You can change this any time in iOS Settings → Privacy & Security → Tracking. Apps without an advertising SDK never show the prompt.
Usage counts (Mixpanel)
Free apps send simple, anonymous events to Mixpanel (for example “app opened”, “feature used”, purchase steps) so we can see what works. Events carry the app version, device model, iOS version, language and region setting, and a random identifier; they do not carry your name, email, Apple Account or phone number, and they do not include what you create in the app. Each app’s section lists anything specific.
Purchases and subscriptions (Apple)
Purchases are sold and charged by Apple through the App Store. For auto-renewing subscriptions payment is charged to your Apple Account at confirmation; they renew unless cancelled at least 24 hours before the period ends, and you manage them in iOS Settings → your name → Subscriptions. Unused free-trial time is forfeited when you subscribe. Apple tells the app only whether you own an item.
Other services named in an app’s section
Some apps use one more service for one feature, named in that app’s section: Countdown Day (OneSignal push notifications, Unsplash photo search) and Calorie AI (OpenAI to recognise food in a photo; Open Food Facts and USDA food databases).
Apple Health
Apps that connect to Apple Health (Sleep Diary, Pulse, Calorie AI) use it only to give you the feature you chose, never for advertising, and Health data is not sent to our analytics or advertising providers. Turn access off any time in iOS Settings → Health → Data Access & Devices.

Countdown Day · Widget & Timer · on the App Store · updated October 10, 2026
Bundle ID com.hon.day · also known as Day, Countdown Timer
Who we are
This policy covers the iPhone and iPad app Countdown Day (shown on the Home Screen as "Countdown Day" and in older versions as "Day"), published on the Apple App Store by Nattapon Kittisuphat ("we", "us"). The Countdown Day website has its own website privacy policy. Where we say "your iPhone", the same applies to an iPad.
What stays on your iPhone
There is no account and no sign-in, so we have no profile of you on any server. Everything you make in the app is stored on your device in the app's private storage:
- your countdowns: name, date and time, note, tag, category, repeat setting, colours, layout and reminder choices;
- photos you choose as backgrounds, saved as a smaller copy inside the app;
- your settings, such as theme, layout and calendar system.
Your Home Screen and Lock Screen widgets read the same storage on the device to show your countdowns. If you used an older version of the app, its countdowns are moved into the new storage on your iPhone; nothing is uploaded to us in the process.
iCloud sync and backup
If you are signed in to iCloud, the app keeps a copy of your countdowns in its area of your private iCloud database (Apple CloudKit), so they can sync between devices signed in to the same Apple Account and come back after you reinstall. This copy is stored by Apple under your Apple Account. We, as the developer, cannot read private iCloud data.
- Auto iCloud Sync is on by default. Day Pro members can switch it off in the app's Settings → Backup & Sync; the change applies the next time you open the app. Anyone can stop the app using iCloud in iOS Settings → your name → iCloud.
- Back Up Now / Restore Data (Day Pro, and people who used the app before version 3.0) saves a second copy of your countdowns to the same private iCloud database and brings it back on request.
- Photos from your library are not copied to iCloud by the app. On a new device, countdowns come back with their text and settings, and you may need to pick a library photo again.
Calendar import
Calendar import is optional and starts only when you open Settings → Calendar Import. iOS then asks you to allow access to your calendar. The app reads events from the next 12 months, on your iPhone, to show you a list. Only the events you select become countdowns, with their title and start date. Your calendar is not sent to us.
To give imported countdowns a background, the app looks for a matching photo on Unsplash. It sends a general theme taken from the event title (for example "birthday cake celebration" for a birthday) or, if no theme matches and the title is written in Latin letters, the event title itself as the search words. If you would rather not send titles, pick the events you import with that in mind, or change the photo afterwards.
Photos and Unsplash
- Your own photos. The app uses Apple's photo picker, so it receives only the photo you choose, not your library. The photo is resized and stored inside the app.
- Saving share cards. When you save a countdown card image, iOS asks for permission to add photos to your library. The app cannot read your library with that permission.
- Unsplash photos. When you browse or search stock photos, the app sends your search words to Unsplash, and the photos load from Unsplash's servers, which, like any website, see your device's IP address. When you choose a photo, the app tells Unsplash that it was used, as Unsplash requires, and credits the photographer.
Reminders and push notifications
Countdown reminders are local notifications scheduled on your iPhone: for example on the day itself, the day before, a week before if you choose, milestones such as 100, 30 and 7 days to go, the halfway point, anniversaries of past days, occasional reminders to come back to the app, and a reminder one to two days before a free trial ends. Their text is created on the device.
The app also includes the OneSignal push service. If you allow notifications, your device registers with OneSignal, which receives a push token and basic device information such as device model, iOS version, language, time zone and app version, so that we can send occasional announcements. Your countdowns are never sent to OneSignal. You can turn notifications off at any time in iOS Settings → Notifications → Countdown Day.
Advertising
Free use of the app is supported by ads from Google AdMob: a full-screen ad from time to time, for example after saving a countdown or when you come back to the app. There are no full-screen ads in the first 24 hours after you first open the app, and at least three minutes between them. AdMob receives device and advertising data to show ads, limit how often you see them, measure them and prevent fraud.
- Consent first. Where the law requires it (for example in the EU, UK and Switzerland), Google's consent form appears before ads load. You can change your choice later in the app's Settings → About → Privacy Settings, a row that appears where consent applies.
- Apple's tracking prompt. The app shows a short explanation, then iOS asks whether the app may track you across other companies' apps and websites. If you allow it, AdMob may use your device's advertising identifier (IDFA) for more relevant ads. If you ask the app not to track, AdMob does not get that identifier. The app works the same either way. Change it any time in iOS Settings → Privacy & Security → Tracking.
- No ads for paying users. Day Pro (yearly, monthly or lifetime), Essentials and the older Remove Ads purchase turn ads off.
Usage analytics
The app sends usage events to Mixpanel so we can see which features help and which get in the way. Events include app opens and sessions, app updates, creating a countdown (with its settings such as unit, background type, category and whether it has a time or note, never the name, note or photo), using quick-add holidays, viewing a countdown, opening a reminder, sharing a card, viewing the purchase screen and purchases (product, price paid and currency), restores, ads shown, the rating prompt, whether you have widgets on screen, your notification permission state, and how many countdowns you created.
Each event carries the app version, device model, iOS version, screen size, your device's region setting, the date the app was first opened and whether you have Day Pro. Mixpanel may estimate an approximate location (country and city) from the connection's IP address. Events are tied to a random identifier created by the app on install. It is not your name, email, Apple Account, phone number or advertising ID, and we do not combine it with any of those. The app also uses Mixpanel feature flags, with the same random identifier, to decide which version of the purchase screen to show.
Purchases
Day Pro, Essentials and older purchases are sold and charged by Apple through the App Store. We never see your card number, name or Apple Account. Apple tells the app which items you own so it can unlock them, and whether you first installed the app before certain features became paid, so long-time users keep them. Purchase events (product and price) are also counted in analytics, as described above.
Web links, feedback and crash reports
- Links to our website. Settings → On the Web, and the menu on some holiday countdowns, open countdownday.com inside the app. These links carry a tag saying they came from the app; nothing about your countdowns is sent. The website's own privacy policy applies there.
- More Apps. The list of our other apps is built into the app and loads nothing from the internet until you tap one, which opens the App Store.
- Feedback. Settings → Feedback opens your Mail app with your message plus the app version, iOS version and device type. We receive your email address only if you send it, and use it only to reply.
- Crash reports. The app has no separate crash-reporting service. If you choose in iOS to share analytics with app developers, Apple may pass us anonymous crash and performance reports.
Children
The app is not directed at children under 13, and we do not knowingly collect personal information from children.
How long data is kept
Data on your iPhone stays until you delete it or the app. The iCloud copy stays in your iCloud until you delete it. Analytics events are kept in Mixpanel only as long as they help us improve the app, and we delete them on request. Google, OneSignal and Unsplash keep data under their own policies, linked above. These services may process data in the United States and other countries.
Your choices and rights
- Stop cross-app tracking: iOS Settings → Privacy & Security → Tracking.
- Change ad consent (where offered): the app's Settings → Privacy Settings.
- Stop notifications: iOS Settings → Notifications → Countdown Day.
- Stop iCloud use: iOS Settings → your name → iCloud, or the Auto iCloud Sync switch for Day Pro members.
- Remove what the app stored on your phone: delete the app. Apple lets you manage data apps keep in your iCloud in iOS Settings → your name → iCloud.
- Ask what we hold, or ask us to delete analytics linked to your device: write to us through the contact form. Laws such as the GDPR and the California Consumer Privacy Act give you these rights. Because the app gives us no name or email, we may ask for details such as your device model and the dates you used the app to find your data.
We do not sell your personal information for money. If you allow tracking, the ad data AdMob uses may count as "sharing" for targeted advertising under some US state laws; asking the app not to track stops it.
Changes and contact
If a future version changes what the app collects, we will update this page before that version is released. The date at the top shows the latest change. Questions about this policy: use the contact form and mention "Countdown Day app". See also the terms of use and support page.
Fall Asleep: Rain Sleep Sounds · on the App Store · updated October 10, 2026
Bundle ID com.hon.zzz · also known as Curing Insomnia, Fall Asleep
The short version: no account, no sign-in, nothing you type is sent anywhere. Free users see ads, and the app sends anonymous usage counts so we can improve it.
This policy covers the iPhone app Fall Asleep: Rain Sleep Sounds (formerly "Curing Insomnia", also shown as "Fall Asleep"), published on the Apple App Store by Nattapon Kittisuphat ("we", "us"). The DozeClock website has its own privacy page.
1. What stays on your iPhone
Your settings, favourite sounds, volume mixes, timer and reminder times, and which themes or rooms you have unlocked are stored only on your device. Records of purchases made in older versions of the app are kept in the iOS Keychain on your device so they carry over. The sleep information shown in the app is built into the app; it is not downloaded about you. There is no account, so we have no profile of you on any server.
2. Anonymous analytics (Mixpanel)
The app sends usage events to Mixpanel so we can see which features work: for example app opens, which sound or room was played, timer use, screens opened, and purchases (product and price). Each event carries the app version, device model, iOS version, screen size, language and region setting, and a random identifier that Apple gives our apps on your device (the "identifier for vendor"). It is not your name, email, Apple ID or phone number, and we do not combine it with any of those. The identifier resets if you delete all of our apps from your device.
3. Advertising (Google AdMob)
Free users may see a full-screen ad between sessions (at most three a day, never in your first session) and can choose to watch a rewarded ad to try a theme or room for 24 hours. Ads are served by Google AdMob, which receives device and advertising data to show and measure ads.
- Consent first. Where the law requires it (for example in the EU, UK and Switzerland) the app shows Google's consent form before any ad loads. You can change that choice later under the app's Settings → Ad Privacy Options.
- Apple's tracking prompt. After the welcome screens, iOS asks whether the app may track you across other companies' apps and websites. If you allow it, AdMob may use your device's advertising identifier (IDFA) for more relevant ads. If you ask the app not to track, it does not get that identifier and ads are less personalised. Sounds work the same either way. You can change this any time in iOS Settings → Privacy & Security → Tracking.
- No full-screen ads for paying users. Subscribers to Plus and owners of the lifetime unlock do not see full-screen ads.
4. Purchases
Subscriptions, the lifetime unlock, room passes and themes are sold and charged by Apple through the App Store. We never see your card number, name or Apple ID. Apple tells the app only which items you own so it can unlock them. Purchase events (product and price) are also counted in our analytics, as described above.
5. Notifications
The app uses local notifications scheduled on your iPhone — the sleep timer, bedtime reminders, a reminder before a free trial ends and, where offered, a nap wake-up alert. They are created on the device; we do not use push notifications from a server. iOS asks for permission first, and you can turn them off in iOS Settings → Notifications.
6. What the app does not use
No microphone, no camera, no location, no contacts, no Apple Health data, no iCloud sync, no sign-in. The app does not record or analyse your sleep.
7. Links from the DozeClock website
Some DozeClock bedtime pages can open the app directly. When that happens the app reads only the wake-up time in the link to suggest a bedtime; nothing is sent back to the website.
8. Crash reports
The app does not include a separate crash-reporting service. If you have chosen in iOS to share analytics with app developers, Apple may pass us anonymous crash and performance reports.
9. How the App Store label matches this page
The App Store privacy label lists: device ID and advertising data (third-party advertising, used for tracking where you allow it), purchases and product interaction (analytics and app functionality), and crash and performance data (app functionality). None of it is linked to your identity.
10. Children
The app is not directed at children under 13, and we do not knowingly collect personal information from children.
11. Your choices and rights
- Stop cross-app tracking: iOS Settings → Privacy & Security → Tracking.
- Change ad consent (where offered): the app's Settings → Ad Privacy Options.
- Remove everything stored by the app on your phone: delete the app.
- Ask what we hold or ask us to delete analytics linked to your device: write to us through the contact form. Under laws such as the GDPR and the California Consumer Privacy Act you have these rights; because we hold no names or emails from the app, we may ask you for the app's support details to find your data.
12. Changes
If a future version changes what the app collects, we will update this page and the App Store privacy label before that version is released. The date at the top shows the latest change.

Sleep Diary: Morning Log · not on the App Store yet · updated October 11, 2026
Bundle ID com.hon.sleep-diary · also known as Sleep Diary
The short version: your diary and any sleep times from Apple Health stay on your iPhone. No account, no sign-in. Free users see ads, and the app sends anonymous counts (like "an entry was saved") with no sleep values in them.
This policy covers the iPhone app Sleep Diary: Morning Log ("Sleep Diary"), published on the Apple App Store by Nattapon Kittisuphat ("we", "us"). The DozeClock website has its own privacy page.
1. What stays on your iPhone
Every diary entry you save — bed and wake times, how long it took to fall asleep, night wakings, how rested you felt, naps, caffeine and notes — plus your usual night and reminder time are stored only on your device. The app does not use iCloud to store or sync them. There is no account, so we have no profile of you on any server. Deleting the app deletes this data.
2. Apple Health (optional)
If you tap "Fill from Apple Health", Sleep Diary asks iOS for permission to read one type of data: Sleep (in bed and asleep times). It uses these times only to pre-fill the entry you are editing; nothing is saved until you tap Save. Sleep Diary never writes to Apple Health and does not read any other health data.
Sleep data from Apple Health, and every diary entry you save, stays on your iPhone. It is never sent to us, to our analytics provider (Mixpanel), or to our advertising provider (Google AdMob), is never used for advertising or marketing, and is not stored in iCloud by the app. You can turn access off at any time in Settings › Health › Data Access & Devices › Sleep Diary.
3. Anonymous analytics (Mixpanel)
The app sends simple counts to Mixpanel so we can see which features are used: for example app opened, entry saved, chart viewed, PDF exported, "Fill from Apple Health" tapped, reminder turned on, and purchase steps (product only). These events carry no sleep times, durations, ratings, notes or Apple Health results — not even whether Apple Health had data. Each event carries the app version, whether Lifetime is unlocked, device model, iOS version, language and region setting, and a random identifier that Apple gives our apps on your device (the "identifier for vendor"). It is not your name, email, Apple ID or phone number, and we do not combine it with any of those.
4. Advertising (Google AdMob)
Free users may see an ad when opening the app (never in your first session) and a full-screen ad after closing the PDF share sheet. You can choose to watch a rewarded ad to see thirty nights and have no ads for 24 hours. Ads are served by Google AdMob, which receives device and advertising data to show and measure ads. AdMob never receives your diary or Apple Health data.
- Consent first. Where the law requires it (for example in the EU, UK and Switzerland) the app shows Google's consent form before any ad loads. You can change that choice later under the app's Settings → Ad privacy options.
- Apple's tracking prompt. On first launch iOS asks whether the app may track you across other companies' apps and websites. If you allow it, AdMob may use your device's advertising identifier (IDFA) for more relevant ads. If you ask the app not to track, it does not get that identifier and ads are less personalised. The diary works the same either way. You can change this any time in iOS Settings → Privacy & Security → Tracking.
- No ads with Lifetime. Owners of the Lifetime unlock do not see ads.
5. Purchase
The Lifetime unlock is sold and charged by Apple through the App Store. We never see your card number, name or Apple ID. Apple tells the app only whether you own it. Purchase steps (product only) are counted in our analytics, as described above.
6. Backup files and PDF reports
With Lifetime you can export a backup file and import it again. The file is created on your iPhone and goes only where you choose to save it (for example the Files app). The PDF report is made on your iPhone and shared through the iOS share sheet to the app or person you pick. We never receive either one.
7. Notifications
If you turn on the morning reminder, the app schedules local notifications on your iPhone. They are created on the device; we do not use push notifications from a server. iOS asks for permission first, and you can turn them off in the app or in iOS Settings → Notifications.
8. What the app does not use
No microphone, no camera, no location, no contacts, no iCloud sync, no sign-in. It does not write to Apple Health or read any health data other than sleep times. The app does not record, measure or score your sleep — it keeps what you enter.
9. Crash reports
The app does not include a separate crash-reporting service. If you have chosen in iOS to share analytics with app developers, Apple may pass us anonymous crash and performance reports.
10. How the App Store label matches this page
The App Store privacy label lists: device ID and advertising data (third-party advertising, used for tracking where you allow it), product interaction (analytics), and crash and performance data. It does not list health data, because sleep data never leaves your iPhone. None of it is linked to your identity.
11. Children
The app is not directed at children under 13, and we do not knowingly collect personal information from children.
12. Your choices and rights
- Stop Apple Health access: iOS Settings › Health › Data Access & Devices › Sleep Diary.
- Stop cross-app tracking: iOS Settings → Privacy & Security → Tracking.
- Change ad consent (where offered): the app's Settings → Ad privacy options.
- Remove everything stored by the app on your phone: delete the app (export a backup first if you want to keep your diary).
- Ask what we hold or ask us to delete analytics linked to your device: email [email protected]. Under laws such as the GDPR and the California Consumer Privacy Act you have these rights; because we hold no names or emails from the app, we may ask you for the app version and device model to find your data.
13. Changes
If a future version changes what the app collects, we will update this page and the App Store privacy label before that version is released. The date at the top shows the latest change.
14. Contact
Questions about this policy: email [email protected] (mention "Sleep Diary"). See also the terms of use and support page.
Funny Voice Changer - Effects · on the App Store · updated October 27, 2026
Bundle ID com.hon.voicechange · also known as Voice Changer, Voice Changer - Sound Effects
- Account: none. No sign-in, no profile of you on any server.
- Ads: the free version may show ads from Google AdMob — see “Advertising” below.
- Usage counts: anonymous counts of what features are used are sent to Mixpanel — see “Usage counts” below.
- Asks iOS for: Microphone (record your voice).
- Leaves your phone besides that: Nothing else.
The app records audio with your microphone so it can apply effects. Recordings are stored on your device until you delete them; we do not upload them or keep them on any server. A recording is shared only when you press share and pick where it goes.
HomeFit - 7 Min Workout Plan · on the App Store · updated October 27, 2026
Bundle ID com.hon.workout · also known as HomeFit, 7 Mins
- Account: none. No sign-in, no profile of you on any server.
- Ads: the free version may show ads from Google AdMob — see “Advertising” below.
- Usage counts: anonymous counts of what features are used are sent to Mixpanel — see “Usage counts” below.
- Asks iOS for: Photos (add only — to save an image you export).
- Leaves your phone besides that: Nothing else.
There is no account. Your plan and settings stay on your iPhone. The app can add an image to your photo library when you choose to save or share one; it does not read your existing photos.
Pulse: Heart Rate Monitor BPM · on the App Store · updated October 27, 2026
Bundle ID com.hon.heart · also known as Pulse, Heart Rate, Pulse: Heart Rate Monitor App
- Account: none. No sign-in, no profile of you on any server.
- Ads: the free version may show ads from Google AdMob — see “Advertising” below.
- Usage counts: anonymous counts of what features are used are sent to Mixpanel — see “Usage counts” below.
- Asks iOS for: Camera (measure your pulse through the camera and light) · Apple Health (read and write heart-rate data, optional) · iCloud key-value storage.
- Leaves your phone besides that: Nothing else.
To measure your pulse the app uses the camera while your fingertip covers it. The camera is used on your iPhone only: the app has no code that uploads images, and it makes no network requests of its own apart from ads, usage counts and Apple purchases. If you allow Apple Health, readings are written to and read from Apple Health on your iPhone. We checked that heart-rate numbers are not included in the usage counts sent to Mixpanel, and Health data is never given to advertisers.
We also count the same anonymous events with our own small usage counter (METER). It stores no advertising identifier, no device identifier, no IP address and no heart-rate values — only the country — and each phone is represented by a random code that changes every day, so days cannot be linked together.
Your readings, notes, values you type in yourself and calm-check results are stored on your iPhone (and in your own iCloud if you turn on backup). A PDF report is created on your iPhone and leaves it only when you choose to share it.
The result is an estimate for general wellness, not a medical measurement.
Where Did I Park - Walk Back · on the App Store · updated October 31, 2026
Bundle ID com.hon.car · also known as Car Finder, Find Car
Car Finder ("the app") is published by Nattapon Kittisuphat. This policy explains exactly what the app does with your data. The short version: your parking spot never leaves your iPhone.
1. Your parking location stays on your device
When you save a spot, the app reads your current GPS position and stores it in the app's own storage on your iPhone, together with the time and how accurate the reading was. This data is never uploaded to us or to anyone else. Deleting the app deletes everything it saved. You can clear the current spot at any time from the home card (More → Clear saved spot).
Location access is requested only while you are using the app, and only for this purpose. The app never tracks you in the background.
Notes, photos and history stay on your device
You can add a one-line note to a saved spot (for example "Level 3 B18"). With Car Finder Plus you can also add a photo of the parking sign, keep your last 20 spots, and keep a separate long-stay pin. Notes, photos, history and the long-stay pin are stored only in the app's storage on your iPhone. They are never uploaded to us, never sent to our analytics or advertising providers, and are deleted with the app. Without Plus, each new save replaces the previous spot; the old spot is not kept.
Camera and photos. The camera is used only when you tap Photo → Take photo, and iOS asks for permission the first time. Choosing an existing picture uses Apple's photo picker, so the app receives only the one photo you pick and cannot see the rest of your library.
Sharing. If you tap Share location, the app creates an Apple Maps link to your spot and hands it to the iOS share sheet. Nothing is sent unless you choose where to share it.
Car Finder Plus (in-app purchase)
Plus is sold and charged by Apple through the App Store, as a one-time Lifetime purchase and, where offered, as a monthly auto-renewable subscription. We never see your card number, name or Apple Account. Apple tells the app only whether you have Plus, so it can unlock it on any device with the same Apple Account (use Restore Purchases). When you buy, an analytics event with the product, price and currency is counted in Mixpanel and METER, without any personal details. Plus removes all ads.
2. Anonymous usage analytics (Mixpanel and METER)
To understand which parts of the app people actually use, we send anonymous events to Mixpanel — for example "app opened", "spot saved", "map opened", "purchase screen viewed", "purchase completed". These events include technical details such as how accurate a GPS reading was, but they never include your coordinates, your address, your name, or your email. No account is required to use the app, and we have no way to tie these events to you personally.
We also count the same anonymous events with our own small usage counter (METER). It receives no advertising identifier, no device identifier and no coordinates; each phone is represented by a random code that changes every day, so days cannot be linked together. Your IP address is not stored; only the country and region it comes from are kept, to count usage per country.
3. Advertising (Google AdMob)
The app is free and shows occasional full-screen ads (none for Car Finder Plus owners) served by Google AdMob. Google may use your device advertising identifier (IDFA) to select ads.
- iOS asks for your permission first through the App Tracking Transparency prompt. If you decline, the app cannot read the IDFA and every ad request is sent as non-personalised.
- That prompt is the only question the app asks about ads. It does not show a separate cookie or ad-consent form. In the EU, the UK and Switzerland, Google therefore serves only "limited ads": no personalisation and no device identifiers, whatever you answer.
- Your saved parking location is never shared with advertisers.
- Like any app that shows ads, Google and its ad partners may infer an approximate location (for example, from your IP address) and may collect device identifiers, app interaction data, and performance or diagnostic data in order to serve and measure ads. That is separate from the precise parking spot you save, which stays on your iPhone.
Google's own policy: How Google uses information from sites or apps that use our services .
4. Notifications
After you save a parking spot for the first time, the app asks whether you want reminders. If you allow them, the app schedules a few local reminders on your device to come back and use it. These are generated on your iPhone — no push server, no message content leaves your device. You can turn them off in iOS Settings at any time.
5. What we do not do
- No account, no sign-up, no password.
- We do not sell data. We have no user database.
- We do not collect your name, email, phone number or contacts, and we never receive your notes or photos.
- We do not upload, share, or store your parking locations.
6. Children
The app is rated 4+ and contains no chat or social features, and notes and photos you add stay on your iPhone. It is not directed at children under 13, and we knowingly collect no personal information from them.
7. Changes
If this policy changes, the date at the top of this page changes with it. Significant changes will be noted in the app's release notes.

Aviation Maintenance Exam Prep · on the App Store · updated September 5, 2026
Bundle ID com.hon.ampprep · also known as A&P Mechanic Test Prep
This app is published by Nattapon Kittisuphat. The short version: it collects nothing, sends nothing, and needs no account or internet connection.
1. No data is collected
The app does not collect, store on a server, or transmit any personal information. There is no account to create, no sign-in, no email address requested, and no analytics or advertising software of any kind inside it.
Your answers, missed-question pile, test scores, and the question you stopped on are saved on your iPhone only, so the app can show the same values when you reopen it. Deleting the app deletes them.
2. No tracking, no advertising
There is no advertising in this app and no tracking of any kind. Because nothing is tracked, the app never shows the "Allow this app to track your activity" prompt — that prompt exists to ask permission for something this app does not do.
3. Works with no internet connection
Every question, answer explanation, and handbook citation is built into the app and runs entirely on your device. The app makes no network requests during normal use. You can keep it in airplane mode permanently and lose nothing.
4. If you email us
The app has buttons that open your mail app to report a problem, suggest a feature, or report a question you believe is wrong. Those buttons pre-fill the app version and your device model so we can answer without asking you questions back. Nothing is sent unless you press send yourself, and we use those messages only to reply to you and fix the issue.
5. Purchases
The app is a one-time purchase through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.
6. Children
The app is a study tool for aviation maintenance technicians preparing for FAA knowledge tests and is not directed at children. Since it collects no data at all, it collects no data from children either.
7. Changes to this policy
If a future version of the app ever collects anything, this page will be updated before that version is released, and the App Store privacy label will be updated to match.
8. Contact

This app is published by Nattapon Kittisuphat. The short version: it collects nothing, sends nothing, and needs no account or internet connection.
1. No data is collected
The app does not collect, store on a server, or transmit any personal information. There is no account to create, no sign-in, no email address requested, and no analytics or advertising software of any kind inside it.
The tool diameters, materials, thread sizes, and machine limits you type are saved on your iPhone only, so the app can show the same values when you reopen it. Deleting the app deletes them.
2. No tracking, no advertising
There is no advertising in this app and no tracking of any kind. Because nothing is tracked, the app never shows the "Allow this app to track your activity" prompt — that prompt exists to ask permission for something this app does not do.
3. Works with no internet connection
Every calculation, table, and reference document runs entirely on your device. The app makes no network requests during normal use. You can keep it in airplane mode permanently and lose nothing.
4. If you email us
The app has buttons that open your mail app to report a problem, suggest a feature, or report a wrong number. Those buttons pre-fill the app version and your device model so we can answer without asking you questions back.

HazMat Guide - NIOSH ERG 2024 · not on the App Store yet · updated September 7, 2026
Bundle ID com.hon.hazmat
This app is published by Nattapon Kittisuphat. The short version: it collects nothing, sends nothing, and needs no account or internet connection.
1. No data is collected
The app does not collect, store on a server, or transmit any personal information. There is no account to create, no sign-in, no email address requested, and no analytics or advertising software of any kind inside it.
The materials you look up are kept in a short recent list saved on your iPhone only, so you can return to them quickly at an incident. Deleting the app deletes that list.
2. No tracking, no advertising
There is no advertising in this app and no tracking of any kind. Because nothing is tracked, the app never shows the "Allow this app to track your activity" prompt — that prompt exists to ask permission for something this app does not do.
The app also never asks for your location. It does not need to know where you are to give you an isolation distance.
3. Works with no internet connection
Every guide, table, and reference entry is stored inside the app itself. The app makes no network requests during normal use. You can keep it in airplane mode permanently and lose nothing — which is the point at a roadside incident with no signal.
4. If you email us
The app has buttons that open your mail app to report a problem or report a wrong number. Those buttons pre-fill the app version, the data edition, and your device model so we can answer without asking you questions back. Nothing is sent unless you press send yourself, and we use those messages only to reply to you and fix the issue.
5. Purchases
The app is a one-time purchase through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.
6. Children
The app is a professional reference tool for emergency responders and is not directed at children. Since it collects no data at all, it collects no data from children either.
7. Source of the reference data
Content is reproduced from public sources: the U.S. DOT Emergency Response Guidebook 2024, 49 CFR Part 172, and the NIOSH Pocket Guide to Chemical Hazards (Source: CDC/NIOSH). This app is independent and unofficial. CDC, ATSDR, HHS, NIOSH, DOT and PHMSA do not endorse it. The same material is available free at cdc.gov/niosh/npg and on the PHMSA website. This is a privacy policy, not a substitute for the disclaimer shown inside the app.
8. Changes to this policy
If a future version of the app ever collects anything, this page will be updated before that version is released, and the App Store privacy label will be updated to match.

Texas Offense Card: Penal Code · not on the App Store yet · updated September 7, 2026
Bundle ID com.hon.texaspenal
This app is published by Nattapon Kittisuphat. The short version: it collects nothing, sends nothing, and needs no account or internet connection.
1. No data is collected
The app does not collect, store on a server, or transmit any personal information. There is no account to create, no sign-in, no email address requested, and no analytics or advertising software of any kind inside it.
What you search for is never recorded or sent anywhere. The only things saved are the settings you choose yourself — appearance and the offense date used for the version warning — and they are saved on your iPhone only. Deleting the app deletes them.
2. No tracking, no advertising
There is no advertising in this app and no tracking of any kind. Because nothing is tracked, the app never shows the "Allow this app to track your activity" prompt — that prompt exists to ask permission for something this app does not do.
3. Works with no internet connection
The full statutory text of the Texas Penal Code, Code of Criminal Procedure, the traffic chapters of the Transportation Code, and the controlled-substance chapters of the Health & Safety Code is built into the app and runs entirely on your device. The app makes no network requests during normal use. You can keep it in airplane mode permanently and lose nothing.
Each card has a button that opens the official page at statutes.capitol.texas.gov in your browser so you can verify the text. That is the only time the app hands anything to another app, and only when you press it.
4. If you email us
Every card has a button to report an error in that section. It opens your mail app with the section number and app version pre-filled so we can find the problem without asking you questions back. Nothing is sent unless you press send yourself, and we use those messages only to reply to you and correct the text.
5. Purchases
The app is a one-time purchase through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.
6. Not an official publication, not legal advice
This app is not an official publication of the State of Texas, TCOLE, or any law-enforcement agency, and it is not legal advice. Statute text is reproduced from the official compilation published by the Texas Legislative Council, with the session and data build date stamped on every card. Arrest, citation, and charging decisions are made solely by the peace officer under the Code of Criminal Procedure, agency policy, and the facts known to that officer.
7. Children
The app is a professional reference for peace officers and is not directed at children. Since it collects no data at all, it collects no data from children either.
8. Changes to this policy
If a future version of the app ever collects anything, this page will be updated before that version is released, and the App Store privacy label will be updated to match.

Inkweek: DBT Diary Card · not on the App Store yet · updated September 24, 2026
Bundle ID com.hon.inkweek · also known as Inkweek
This app is published by Nattapon Kittisuphat. The short version: Inkweek collects nothing, needs no account, and keeps your diary card on your device.
1. No data is collected
Inkweek does not collect, transmit, or store personal information on a server. There is no account, sign-in, analytics, advertising, tracking, or third-party SDK. The developer cannot see what you enter.
2. Your diary stays on your device
Feelings, urge entries, whether you acted on an urge, skills used, notes, custom lists, and settings are stored only on your device. Inkweek protects its files with iOS complete file protection so they are unavailable while the device is locked.
Inkweek has no cloud sync of its own. Like other app data, your diary is included in your iPhone's own backups (iCloud Backup or a backup to your computer) if you use them, so it can come back when you restore or set up a new iPhone. Those backups belong to your Apple account or your computer — not to us. Deleting the app removes the diary from your iPhone; a backup made earlier keeps its copy until that backup is deleted.
3. No network connection is used
The app has no networking code and makes no network requests. Logging, the week sheet, history, and PDF or CSV creation all work offline.
The Get help now screen can hand a phone number, text number, or public directory link to the iOS Phone, Messages, or Safari app only after you tap it. Inkweek does not send your diary data with those actions.
4. Exports are controlled by you
PDF and CSV exports are created on the device. They leave Inkweek only after you tap Share and choose a destination in the iOS share sheet. Inkweek does not upload or email an export itself. A temporary export file is removed after the share sheet closes.
5. Optional local reminders
The Daily reminder setting uses an iOS local notification scheduled on your device. Permission is requested only after you turn that setting on. Inkweek does not use remote push notifications, and you can turn the reminder off at any time.
6. App Lock and Face ID
App Lock is optional. It asks iOS to confirm the device owner with Face ID or the device passcode. The system returns only whether authentication succeeded. Inkweek never receives, reads, or stores your face scan or any other biometric data. A privacy cover hides diary content whenever the app is inactive.
7. Not a medical device
Inkweek is a personal diary card. It is not a medical device, gives no medical or mental-health advice, and is not a crisis service. Use it alongside your own therapist or doctor.
In immediate danger, call your local emergency number. The Get help now screen provides crisis-line numbers for several countries and a public directory for other countries; those outside services have their own privacy practices.
8. Changes to this policy
A future version that changes these privacy practices will update this page and the App Store privacy label before release.

Crosswind E6B Flight Computer · not on the App Store yet · updated September 19, 2026
Bundle ID com.hon.crosswinde6b
This app is published by Nattapon Kittisuphat. The short version: core calculations work fully offline, the app sends nothing automatically, and it has no analytics, no advertising, no tracking and no account. Links and support email use Apple's system services only when you choose them.
1. Nothing is collected automatically
The app does not collect, store on a server, or transmit any personal information on its own. There is no account to create, no sign-in, no email address requested, and no analytics or advertising software of any kind inside it. The only way anything leaves your iPhone is a support email you choose to send (section 5).
The numbers you type into any mode — wind, true course, airspeed, fuel burn, altitude, or the weight & balance worksheet — are saved on your iPhone only, so the app can show the same values when you reopen it. Your unit preferences (knots vs. mph, inHg vs. hPa, and so on) are saved the same way. Deleting the app deletes all of it.
2. No tracking, no advertising
There is no advertising in this app and no tracking of any kind. Because nothing is tracked, the app never shows the "Allow this app to track your activity" prompt — that prompt exists to ask permission for something this app does not do.
3. Works with no internet connection
Every calculation — wind correction angle, true and magnetic heading, ground speed, fuel, density altitude, true airspeed, and weight & balance — runs entirely on your device using the formulas shown in the app's own "Show work" screens. The app itself makes no network requests. You can keep it in airplane mode permanently and lose no calculation.
Three buttons hand off to Apple's system services, and only when you tap them: "Open the web version" of this policy opens Safari, "More apps by the developer" opens the App Store, and "Rate" uses the App Store rating sheet.
4. Not a certified flight instrument, not a substitute for training
Crosswind E6B is an educational and planning aid only. It is not a certified Electronic Flight Bag (EFB) and must not be used as a primary or sole source of information for flight, navigation, or any safety-of-flight decision.
Always verify calculations against your aircraft's Pilot's Operating Handbook (POH), current official weather briefings, and cross-check with a certified flight instructor or dispatcher before flight. Weight & balance results must be verified against the aircraft's POH/AFM and current weighing report. The developer assumes no liability for errors or decisions made based on this app's output.
5. If you email us
The Settings screen has buttons to report a problem, suggest a feature, or report a wrong number, and every "Show work" screen has its own "Report a number" button. Those buttons open your own mail app with the whole message in view, so you can read or change it before you send it.
Every support email includes the app version, device model, iOS version, and your language and region. Problem and number reports add your unit and precision settings; "Report a number" also adds the exact inputs and results you were looking at. They are pre-filled so we can answer without asking you questions back. If no mail account is set up, the message is copied for you to paste instead.
Nothing is sent unless you press send yourself, and we use those messages only to reply to you and fix the issue.
6. Purchases
The app is a one-time purchase ($9.99) through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.
7. Children
The app is a professional tool for pilots and student pilots and is not directed at children. Since it collects nothing on its own, it collects nothing from children either.
8. Changes to this policy
If a future version of the app ever collects anything, this page will be updated before that version is released, and the App Store privacy label will be updated to match.

FERS Retirement Date Planner · not on the App Store yet · updated September 19, 2026
Bundle ID com.hon.fersplanner
This app is published by Nattapon Kittisuphat. The short version: it collects nothing, sends nothing on its own, and needs no account or internet connection.
1. No data is collected
The app does not collect, store on a server, or transmit any personal information. There is no account to create, no sign-in, no email address requested, and no analytics or advertising software of any kind inside it.
Everything you enter to build your retirement timeline — your date of birth, service computation date, retirement type, high-3 salary, sick leave hours, military deposit time, survivor election, and any saved scenarios you name and keep — is stored on your iPhone. The app never sends it to us, and we never see it.
Like other app data, your saved plans are included in your iPhone's own backups (iCloud Backup or a backup to your computer) if you use them, so they can come back when you restore or set up a new iPhone. Those backups belong to your Apple account or your computer — not to us. Deleting the app removes the plans from your iPhone; a backup made earlier keeps its copy until that backup is deleted.
2. No tracking, no advertising
There is no advertising in this app and no tracking of any kind. Because nothing is tracked, the app never shows the "Allow this app to track your activity" prompt — that prompt exists to ask permission for something this app does not do.
3. Works with no internet connection
Every calculation — your annuity multiplier, reductions, the FERS Supplement, COLA, and the effect of each date on your timeline — runs entirely on your device using the formulas shown in the app's own "Why this changed" and "Rules & sources" screens. The app makes no network requests during normal use. You can keep it in airplane mode permanently and lose nothing.
4. Not an official OPM tool, not financial, legal, or tax advice
This app is not affiliated with, endorsed by, or connected to the U.S. Office of Personnel Management (OPM) or any U.S. Government agency. Every result is an estimate built for planning purposes from publicly available law and guidance — 5 U.S.C. Chapter 84, its implementing regulations in 5 CFR, and the OPM CSRS-FERS Handbook — explained in the app's own words, with the section or chapter cited next to every number.
Your official annuity is computed by OPM from your Official Personnel Folder, and can differ from this app's estimate. Verify with your agency HR/benefits office before choosing a retirement date. The app gives no guarantee of accuracy and is not financial, legal, or tax advice; the developer assumes no liability for decisions made based on its output.
5. If you email us
"Flag a figure", "Report a problem" and "Suggest a feature" (in Settings, and "Flag a figure" on the explanation screens) first show you the whole message inside the app, where you can change or delete anything. It contains the result shown, the rules version, the app version, your iPhone model and iOS version. Your plan's personal details — birth date, service dates, pay and the other entries — are added only if you switch them on. Nothing leaves the app until you choose Mail, Share, or Copy yourself; Copy keeps the text on this iPhone's clipboard only and clears it after 10 minutes. We use those messages only to reply to you and correct the figure.
6. Purchases
The app is a one-time purchase ($9.99) through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.
7. Children
The app is a planning tool for federal employees under the FERS retirement system and is not directed at children. Since it collects no data at all, it collects no data from children either.
8. Changes to this policy
If a future version of the app ever collects anything, this page will be updated before that version is released, and the App Store privacy label will be updated to match.

This app is published by Nattapon Kittisuphat. The short version: Binyan works fully offline, sends nothing automatically, and has no analytics, no advertising, no tracking and no account. Links and support email use Apple's system services only when you choose them.
1. Nothing is collected
The app does not collect, upload or share any personal information. There is no sign-in, no email address requested, and no analytics or advertising software inside it.
Your practice history — which verb forms you answered, your accuracy per cell of the Paradigm Map, your review queue and your settings — is saved on your iPhone only so the map keeps its colors when you reopen the app. Deleting the app deletes all of it. You can also erase it any time with Settings › Reset all progress.
2. No tracking, no advertising
There are no ads and no tracking of any kind, so the app never shows the "Allow this app to track your activity" prompt.
3. Works with no internet connection
Every verb form, verse and gloss is stored inside the app. The app makes no network requests. A few buttons hand off to Apple's system services only when you tap them: the web version of this policy and the link to the source data open Safari, "More apps" opens the App Store, and "Rate" uses the App Store rating sheet.
4. If you email us
"Report a problem", "Suggest a feature" and "Report this form" open your own mail app with the message in view, so you can read or change it before sending. Reports include the app version, device model, iOS version and language, and a form report also includes the verb form, its verse reference, its tagging and your answer, so we can check it without asking you questions back. If no mail account is set up, the message is copied for you to paste instead. Nothing is sent unless you press send yourself.
5. Exporting the data
Settings › Where the forms come from › Export corpus creates a JSON file of the verb data on your device and hands it to the iOS share sheet. Where it goes next is your choice.
6. Purchases
Binyan is a one-time purchase through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.
7. Children
The app is a study tool for students of Biblical Hebrew and is not directed at children. It collects nothing from anyone, including children.
8. Data sources
Hebrew text: Westminster Leningrad Codex (public domain). Morphology and lemma tags: original work of the Open Scriptures Hebrew Bible project, available at https://github.com/openscriptures/morphhb , licensed CC BY 4.0. Glosses: Strong's Hebrew Dictionary (1890), public domain, XML markup by Open Scriptures (CC BY 4.0). Binyan is not affiliated with or endorsed by Open Scriptures.

Pool Water Log & Calculator · not on the App Store yet · updated September 27, 2026
Bundle ID com.hon.poolwaterlog
This app is published by Nattapon Kittisuphat. The short version: your pools, test readings and products stay on your iPhone, the app sends nothing automatically, and it has no analytics, no advertising, no tracking and no account.
1. Nothing is collected automatically
The app does not collect, store on a server, or transmit any personal information on its own. There is no account, no sign-in and no analytics or advertising software inside it.
Everything you enter — pools and hot tubs, volumes, test readings, targets, products, doses and reminders — is saved on your iPhone only, in the app's own storage. It is included in your normal iPhone backup, which Apple handles under your own account. Deleting the app deletes the data.
2. Exports and backups stay with you
The Export screen can create a CSV file, a PDF season report or a backup archive. These files are made on your iPhone and go only where you send them with the system share sheet or Files (for example your own iCloud Drive). Importing an archive reads only the file you pick. We never receive these files.
3. Notifications are local
Reminders (test again, clean filter, backwash, your own) and the wait-timer alert are scheduled on your iPhone by iOS. The app asks for notification permission only when you turn on a reminder or start a wait timer. If you decline, every other part of the app still works. No push server is involved.
4. No tracking, no advertising, no internet needed
There is no advertising and no tracking of any kind, so the app never shows the tracking permission prompt. The app makes no network requests and uses no camera, location or Bluetooth; it works fully in airplane mode. A few buttons hand off to Apple's system services only when you tap them: this policy in Safari, "More apps by the developer" in the App Store, the App Store rating sheet, and the share sheet when you export.
5. If you email us
The Settings screen and the "Flag a figure" button can open your own mail app. The message is pre-filled with the app version, device model, iOS version and unit setting, and — when you flag a figure — the pool name and volume, the reading and the dose step you are asking about, so we can check the calculation. You see the whole message and nothing is sent unless you press send. If no mail account is set up, the text is copied for you to send yourself. We use it only to reply and fix the issue.
6. Calculations are based on what you enter
A calculator and logbook for pool and hot tub owners who already know how to handle pool chemicals. It is not a chemical handling guide, not safety advice, and does not replace the product label or a pool professional. Every amount is computed from the readings, pool volume and product strengths you enter; the developer does not verify your inputs and assumes no liability for results or decisions based on this app. Wait times are minimum mixing times, not a rule for when the water may be used.
7. Purchases
The app is a one-time purchase through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.
8. Children
The app is a tool for pool owners and is not directed at children. It collects nothing from anyone.

Shot List & Shoot Day Board · not on the App Store yet · updated September 27, 2026
Bundle ID com.hon.shotlistboard
This app is published by Nattapon Kittisuphat. The short version: your projects stay on your iPhone, the app sends nothing automatically, and it has no analytics, no advertising, no tracking and no account.
1. Nothing is collected automatically
The app does not collect, store on a server, or transmit any personal information on its own. There is no account, no sign-in and no analytics or advertising software inside it.
Your projects — scenes, shots, shoot days, notes and reference photos — are saved on your iPhone only, in the app's own storage. Deleting the app deletes them. To keep a copy, export a project file, PDF or CSV from the Export screen and save it wherever you choose.
2. Photos
When you add a reference photo to a shot, you pick it with Apple's system photo picker. The app only receives the photos you pick — it never asks for access to your photo library and cannot see anything else in it. Picked photos are copied into the project on your iPhone.
3. No tracking, no advertising, no internet needed
There is no advertising and no tracking of any kind, so the app never shows the tracking permission prompt. The app makes no network requests; it works fully in airplane mode. A few buttons hand off to Apple's system services only when you tap them: this policy in Safari, "More apps by the developer" in the App Store, the App Store rating sheet, and the share sheet when you export.
4. If you email us
The Settings screen can open your own mail app to report a problem, suggest a feature or report a wrong wrap time. The message is pre-filled with the app version, device model and iOS version, and counts of scenes, shots and days (never your project's name). "Report a wrong time" also includes the call time and the shot codes, lengths and statuses of the day you have open. You see the whole message and nothing is sent unless you press send. We use it only to reply and fix the issue.
5. Estimates only
Wrap time and ahead/behind are estimates based on the shot lengths you enter and the order on the board. They are not a promise of when the day ends.
6. Purchases
The app is a one-time purchase through the App Store. Apple handles the transaction; we never see your payment details. There is no subscription and no in-app purchase.
7. Children
The app is a production tool and is not directed at children. It collects nothing from anyone.
8. Changes to this policy
If a future version ever collects anything, this page and the App Store privacy label will be updated before that version is released.

5. Apps that store credentials (One Time Password)
The One Time Password app stores sensitive credentials on your device. This section describes how that data is protected.
- 2FA seeds (TOTP secrets): Encrypted with ChaChaPoly using a master key stored in the iOS Keychain (hardware-protected by the Secure Enclave). The plaintext seed never leaves the device unencrypted.
- Passwords: Each password field is encrypted with the same master key before being written to local storage (SwiftData). Titles, usernames, and URLs are stored in plaintext so search works — passwords themselves are never readable from the database file.
- iCloud Sync (Pro, optional): When enabled, encrypted records sync via Apple's
CKRecord.encryptedValuesAPI in your private CloudKit database. With Apple Advanced Data Protection on, sync is end-to-end encrypted — Apple cannot read your data. We never see your data either way. - Master key: Generated on first launch using
SecRandomCopyBytesand stored with the Keychain accessibility flagkSecAttrAccessibleWhenUnlockedThisDeviceOnly. It is never transmitted to any server we control. - Camera: Used solely to scan QR codes for adding 2FA accounts. No images are stored, recorded, or transmitted. Camera access is requested only when you open the QR scanner.
- Clipboard auto-clear: When you copy a code or password, the clipboard is automatically cleared after 60 seconds to reduce exposure to other apps.
- App Lock: Optional Face ID / Touch ID / passcode lock gates access to the vault. The PIN (if set) is salted and hashed before being stored in the Keychain.
- Encrypted backup export (Pro): Optionally produces a passphrase-encrypted file you save to Files or AirDrop. Loss of the passphrase makes the backup unrecoverable.
- Legacy data migration: If you used a previous version of One Time Password to store passwords, those records are read from local storage, re-encrypted with the new master key, and made available in the Passwords tab. The legacy file is never deleted automatically.
- No backend: We do not operate a server that stores your credentials. There is no APP26 account, no APP26 cloud, and no APP26 employee with access to your data.
- Auto-renewable subscription: Annual Pro renews yearly via your Apple ID. Cancel anytime in Settings → Apple ID → Subscriptions; cancellation takes effect at the end of the current period.
- Analytics scope: Mixpanel events for One Time Password contain only metadata (counts, action types, timestamps). Seed values and password contents are never sent to analytics.
6. Your choices and rights
- Stop cross-app tracking: iOS Settings → Privacy & Security → Tracking.
- Change ad consent (where offered): the app’s Settings → ad privacy options.
- Turn off any permission: iOS Settings → the app.
- Remove everything an app keeps on your phone: delete the app (export a backup first if the app offers one and you want a copy).
- Ask what we hold or ask us to delete analytics linked to your device: email [email protected]. Laws such as the GDPR and the California Consumer Privacy Act give you these rights; because we hold no names or emails from the apps, we may ask for the app name, version and device model to find your data.
7. Changes
If a future version of an app changes what it collects, we update this page and the App Store privacy label before that version is released. The date at the top shows the latest change; each app’s section shows when it was last reviewed.
