Really Really Hard Sudoku — Privacy Policy
Last updated: October 12, 2026
Really Really Hard Sudoku does not collect, store on a server, share, or sell any personal information.
- No accounts. The app doesn’t ask who you are.
- No tracking or analytics. The app contains no advertising, analytics, or tracking code.
- Your data stays on your device. Games in progress, settings, and statistics are saved only on your iPhone. They are removed if you delete the app.
- No network access. The app works entirely offline.
- Sharing. If you use Share after a solve, the text is passed to the share sheet you choose; the app itself sends nothing.
