Short version: Sudoku collects nothing, sends nothing, and requires no account or internet connection. Everything happens entirely on your device.

Information We Collect
We do not collect, store, or transmit any personal information. The app has no accounts, no sign-in, and no analytics or tracking tools of any kind.
Data Stored on Your Device
The app saves a small amount of gameplay data locally on your device so it can remember your progress:
- Your best completion time for each difficulty level.
- Basic app preferences.
This data never leaves your device. It is removed if you delete the app.
Network & Internet Access
Sudoku works completely offline. Every puzzle is generated on your device, so the app does not make network requests and does not send any data to us or to third parties.
Third-Party Services
The app contains no advertising, no third-party SDKs, and no external analytics. Nothing is shared with anyone.
Children's Privacy
Because the app collects no personal information from anyone, it is safe for users of all ages, including children.
Changes to This Policy
If this policy changes, the updated version will be posted on this page with a new "Last updated" date.
