1. There is no account to log into

Free Sudoku creates no account and keeps no copy of anything about you on a server. All game data — puzzles, progress, statistics, the daily challenge calendar and settings — stays only in the app's private storage on your phone. Deleting it there removes it everywhere.

2. Delete your game data

There are two ways to do this. Both remove all game data right away:

Uninstall the app. Press and hold the Free Sudoku icon, choose Uninstall, and confirm. The app and all its data are removed.

Or clear the app's data. In Android settings, go to Settings → Apps → Free Sudoku → Storage → Clear data. Menu names vary slightly between Android versions. The app restarts empty, as if newly installed.

3. Reset or delete your advertising ID

Ads in the game are tied to your device's advertising ID, not to your name. On Android, you control it in Settings → Google → Ads. Use Delete advertising ID (Android 12 and newer) to remove it, or Reset advertising ID on older versions to start fresh. The same screen lets you opt out of ad personalisation.

4. Requests about our advertising partners

Our advertising partners (Unity LevelPlay and Unity Ads, Liftoff/Vungle, Yandex/Yango Ads and Meta) may process technical data as described in our privacy policy. Because we hold no account data ourselves, send requests about that data to each partner through the links in the policy, or write to contact@freesudoku.app and we will point you to the right place.
