Killer Sudoku has no accounts and no sign-in. The game saves your statistics (games started and won, win rate, best and average times, daily streaks) on your device only. An unfinished board is never saved.
The app uses Firebase Analytics, provided by Google, to collect gameplay events: puzzles started, puzzles completed, hint use, and taps on the share and more apps surfaces. An event carries the level, the puzzle's id, whether the game was the daily challenge, and how long a win took. It never carries your entries, notes, or unfinished boards.
If you share a result, the share text (the level, the puzzle, and your time) goes to the app you pick in the system share sheet. Killer 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, and hints are free, with no wait and no ad.
