Fiber TrackerPrivacy Policy
Last updated October 8, 2026
Fiber Tracker is made by Peak Apps Studio (Doruk Çetin, individual developer). This policy explains what happens to your information when you use the Fiber Tracker app for iOS and Android and this website.
The short version
We don’t collect any personal data. There is no account, no advertising and no location tracking, and we run no analytics of our own. Your food log, goals and gut check notes stay on your device.
What you enter in the app
Your goals, the details you give for them (sex, age group and optional weight), the foods you log, water, gut check entries and your own foods 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 export a CSV file or a backup, the app hands the file to the share sheet and you decide where it goes.
Camera
The camera is used only to read food barcodes while the scanner is open. No photos or video are taken or saved. The barcode is read on your phone; on Android this is done by Google’s ML Kit (see the table below).
Services the app talks to
| Service | When | What is sent |
|---|---|---|
| Open Food Facts | When you look up a barcode | Only the barcode number of the product. Open Food Facts is a free, open food database; see its privacy policy at openfoodfacts.org. |
| 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. |
| Google ML Kit (Android only) | When the barcode scanner is used | The barcode is read on the phone and camera images never leave it. ML Kit may send Google technical diagnostics such as the device model, app version, an install identifier and performance data, under Google’s privacy policy. |
| Expo (app updates) | When the app starts | A check for bug-fix updates with technical details such as the app version, platform and a random install identifier, not your food log. |
| Websites you open | Only when you tap a link | They open in the browser; the app sends them nothing. |
Notifications
Reminders are scheduled on your device. No server sends them.
This website
The website has no cookies, analytics or ads. Our web host keeps standard server logs, such as IP addresses, for security. The calculator runs in your browser; nothing you type is sent anywhere.
Children
Fiber Tracker 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.
