Sudoku Atlas — Last updated July 2026
Sudoku Atlas does not collect, transmit, or share any personal information. All puzzle progress, settings, and statistics are stored locally on your device and never leave it.
The app makes no network requests. There are no analytics, advertising, or crash-reporting services.
Your purchase is processed entirely by the store you bought the app from — the App Store on iOS, Google Play on Android, or Steam on desktop. We never see your payment details. Each store keeps its own record of the transaction (and, in Steam's case, of which games you own and your playtime) under its own privacy policy; the app itself sends them nothing.
