Privacy Policy
Last updated September 25, 2026
Citizenship Clock is made by Peak Apps Studio (Doruk Çetin, individual developer). This policy explains what happens to your information when you use the Citizenship Clock app for iOS and Android and this website.
The short version
We don’t collect any personal data. There is no account, no analytics, no advertising and no location tracking. Your green card date and travel history stay on your device.
What you enter in the app
Your “Resident since” date, your path, your trips, countries and notes are stored in a database inside the app on your device. We never receive them. Your phone may include them in its own device backup (iCloud or Google), which your device settings control.
If you import your I-94 travel history, you paste the text into the app yourself; it is read on your device and never sent anywhere. If you export a PDF, CSV or backup, the app hands the file to the share sheet and you decide where it goes.
Services the app talks to
| Service | When | What is sent |
|---|---|---|
| Apple App Store / Google Play | When you buy, restore or open the app | Handled by Apple or Google under their privacy policies. We don’t receive payment details; the app only asks the store whether you have Pro. |
| Expo (app updates) | When the app starts | A check for bug-fix updates with technical details such as the app version and platform, not your data. |
| Websites you open (USCIS, CBP) | Only when you tap a link | They open in the browser; the app sends them nothing. |
Notifications
Trip alerts and filing reminders are scheduled on your device. No server sends them.
This website
The website has no cookies, analytics or ads. Our host (Netlify) keeps standard server logs, such as IP addresses, for security. The calculator runs in your browser; nothing you type is sent anywhere.
Children
Citizenship Clock is not directed at children under 13 and we don’t knowingly collect information from them.
Your choices and rights
Because we hold no personal data about you, there is nothing for us to access, correct, sell or delete. You can erase everything in the app at any time (Settings → Erase all data) or by deleting the app. See Delete your data. We do not sell or share personal information.
