Privacy Policy — Sudoku

Last updated: 24 October 2026

This policy explains how the Sudoku app (“the app”), developed by Furkan Yılmaz, handles your information on iOS and Android.

In short

The app does not collect, store on a server, share or sell any personal data. It has no accounts, no advertising, no analytics and no tracking. Everything the app remembers stays on your device.

What stays on your device

To work, the app saves the following on your device only:

• your games: boards in progress, finished and ended games, times, mistakes and hints used, and favourites;
• your settings: theme, accent colour, language, font, text size, haptics and the game options.

This information is never sent to us or to anyone else. Deleting the app deletes it.

On Android, the app’s data is excluded from Google’s device backups. On iPhone and iPad, it can be part of the backup you make of your device through iCloud or your computer; that backup is handled by Apple under its own policies.

Device features

• Motion sensor: while the profile page is open, the app may read the device’s motion sensor to recognise a shake. The reading is used on the device at that moment only; it is not stored or sent anywhere.
• Haptics: the app uses the device’s vibration to give feedback. No information is collected for this.
• App icon: the app can change its own icon to match your accent colour. This happens on the device.
• Notifications: if you allow them, the app reminds you at noon when the day's puzzle is waiting, and a day after you leave a game unfinished. The reminders are scheduled on the device from your games there; nothing is sent to us or to anyone else, and they can be turned off in the app's settings or the device's.

The app does not access your camera, microphone, location, contacts, photos or any other personal content.

Ratings

If you choose to rate the app, the rating window is provided by the App Store or Google Play, and your rating is handled by Apple or Google under their own privacy policies. The app does not receive it.
