Your puzzle stays yours.

Luma Sudoku is designed to work without collecting personal data.

Data we collect

None. The app contains no analytics SDK, advertising SDK, cross-app tracking, account system, or server-side profile.

Data stored on your device

Your current puzzle, entries, notes, elapsed time, mistakes, and hint balance are saved locally so you can continue later. Removing the app removes this local data.

Network access

The current version does not need a network connection for gameplay.

Children

Because the app does not collect personal information, it does not knowingly collect information from children.
