SudokuSudoku privacy policy
Effective: 25 October 2026 · App: Sudoku (com.damurka.sudoku) · Developer: Damurka
Sudoku is a puzzle game. You don't need an account and we don't ask for your name, email, location, contacts or photos. This page explains what data the app and the services built into it handle, and the choices you have.
Data kept on your device
Your games, statistics, coins, levels, settings and purchases you've unlocked are stored only on your phone. They are deleted when you uninstall the app or clear its data.
Services that receive data
| Service | What it receives | Why |
|---|---|---|
| Google AdMob (free version only) | Advertising ID, device and app information, approximate location from IP address, ad interactions | To show ads and measure them. Where the law requires it (for example in the EEA and UK) we ask for your consent first and you can change it at any time in Settings > Privacy options. |
| Google Firebase Analytics | App interactions (for example puzzles started and won), device and app information, an app-instance ID | To understand which features are used and improve the game. Only collected once consent allows it. |
| Google Firebase Crashlytics | Crash logs, device and app information, an installation ID | To find and fix crashes. |
| Google Play Billing | Handled by Google Play; we only receive a purchase token | To unlock Sudoku Pro and add coins you buy. |
| Google Play Games (only if you sign in) | Your Play Games player ID, achievements and leaderboard scores | To show achievements and leaderboards. |
These services are run by Google under their own policies: Google Privacy Policy and how Google uses data from apps that use its services.
We don't sell your data
We don't sell personal data and we don't share it except with the services above, which work on our behalf.
Notifications
If you turn on the daily reminder, the app schedules a notification on your device. Nothing is sent to us.
Children
Sudoku is not directed at children under 13 and we don't knowingly collect data from them.
