Common questions
Do I need an internet connection or an account?
The current Sudoku features work offline without registration. Network use by system backups depends on your system service and device settings.
Where can I download the app?
The HarmonyOS phone edition is being prepared for release. There is no official download link yet. Check this website and AppGallery for future availability.
Where is my progress saved?
Progress, statistics and settings are stored locally on the current device. Clearing app data or uninstalling affects these records. System backup and restoration depend on your device services and settings. There is no developer account or cross-device cloud save service.
How do I change the left/right layout?
Choose your preferred hand in settings. Automatic hand awareness is off by default and can be enabled by choice. If your device does not support it, use the manual layout.
What does puzzle import read?
The app reads clipboard text only when you choose to import a puzzle or seed. Copy the intended puzzle text first and avoid unrelated sensitive information.
How do I delete my data?
Clear the app's data through system app management. This removes local progress, statistics and preferences. If you use system backup, manage backup copies separately.
What helps with a bug report?
For a bug report, include your phone model, HarmonyOS version, app version, steps to reproduce the issue, and what you expected to happen. Add screenshots without personal information if useful. Do not send passwords, identity documents or unrelated sensitive logs.
