Privacy Policy
Last updated 29 August 2026
OneHand Sudoku does not collect any data about you.
That is the whole policy. Here is the detail.
What the app stores
The app saves your progress on your device, in the app's own storage: which levels you have finished, your best time on each, how many mistakes you made, the help setting you chose, the theme you picked, and any half-finished board. Nobody else can read it. Deleting the app deletes all of it.
What the app sends
Nothing. OneHand Sudoku has no network code. It never contacts a server, because there is no server. It works exactly the same in aeroplane mode.
What the app does not do
- No account, no sign-in, no email address.
- No analytics, no crash reporting, no advertising, no third-party SDKs.
- No tracking, no advertising identifier, no data shared with anyone.
- No location, contacts, photos, microphone, camera, or health data.
Children
The app is rated 4+ and is safe for children. Since it collects nothing from anyone, it collects nothing from children either.
Changes
If a future version ever collects anything, this policy will be updated before that version ships, and the App Store privacy label will change to match.
