Advanced Sudoku has no accounts, no ads and no analytics. Your games stay on your device.

What is stored

Your games, settings, statistics and Academy progress are saved only on your device. Uninstalling the app deletes them; Android may include them in your own device backup.

No tracking

The app does not collect personal data, does not show ads and does not use analytics or advertising identifiers. It does not send your games anywhere.

Notifications

Daily reminders are off by default. When you turn them on, they are scheduled on your device; no server is involved.

Camera and photos

The scanner uses the camera or a photo you pick only when you ask for it. The picture is read on your device to find the digits, then discarded: it is neither stored nor uploaded.

Sharing

Duel codes and daily results leave your device only when you share them yourself, through the apps you choose. They contain the puzzle code, the difficulty and your time. If you install the app from a challenge or daily link, it reads that link once from Google Play to open the right puzzle; nothing is sent anywhere.

Google services

Digit recognition uses a model provided by Google Play services on your device. Google Play services may send Google anonymous performance and diagnostic data about this feature. Purchases and, if you use them, Google Play Games features are handled by Google under its own privacy policy.

Children

The app is suitable for all ages and collects no data from anyone, children included.

Changes

If this policy changes, the new version will be published here with its date.
