Sudoku Notebook · Last updated: 2 October 2026
In short: Sudoku Notebook does not collect, store or share any personal data.
Your current game, best times and settings are stored only on your device. They are never sent to us.
Your gold balance is stored in your own iCloud account so it can sync between devices that use the same Apple Account. We have no access to it.
Gold packs are sold through Apple's App Store. Apple processes the payment; we never see your payment details or identity.
The app contains no ads, analytics, tracking or third-party services. No account is needed to play.
The app is suitable for all ages. Because it collects no personal data from anyone, it collects none from children either.
If this policy changes, the new version will be published on this page and the date above will be updated.
