Classic Sudoku has no accounts and no sign-in. The game saves your statistics record (games played and won per level, win times, and your daily streak) on your device only.

The app uses Firebase Analytics, provided by Google, to collect gameplay events: puzzles started, puzzles completed, hints used, and taps on the share and more apps surfaces. An event carries the puzzle's level, whether it was the daily challenge, and counts and outcomes (mistakes, hints used, win time). It never carries your moves: the numbers you place, your notes, and your board are never sent.

If you share a result, the share text (your result summary) goes to the app you pick in the system share sheet. Classic Sudoku does not send it anywhere itself.

Deleting your data: everything the game stores sits on your device only, so deleting it takes one step: uninstall the app, and its stored data is removed with it.

Your data is never sold, and it is never used for advertising. The app serves no ads.
