Data We Collect
None. Sudoku by Pixol does not collect personal information, details about how you use the app, ad IDs, contact details, location data, or account information.
Data Stored on Your Device
The app stores local data so Sudoku works as expected:
- Current game progress, including filled numbers, original clues, pencil notes, timer, mistakes, difficulty, puzzle answer, and undo history.
- Daily challenge progress, completion history, streaks, times, mistakes, and star ratings.
- Game statistics, including win counts, streaks, best times, and star totals.
- Gameplay preferences such as remaining count, vibration feedback, sound, theme, language, notification settings, reminder time, and whether reminder prompts have been shown.
This data is saved by the app on your device. It is not sent to Pixol or shared with other companies by Sudoku by Pixol.
Device Backups
If phone backup is enabled on your device, your device provider may back up app data according to your system and account settings. Sudoku by Pixol does not operate that backup and does not receive your backed-up data.
