1. Introduction
Welcome to Alien Sudoku (“the App”).
The App is an offline single-player puzzle game: no registration, no ads, no social features, and no in-app purchases in the current release.
2. Information we collect
2.1 Summary
We do not actively collect, upload, sell, or share your personal information.
The App does not declare INTERNET. Gameplay and settings stay on your device
and are not sent to a developer server.
2.2 Local settings
Stored on-device via SharedPreferences:
| Data | Purpose | Uploaded |
|---|---|---|
| SFX volume | Remember volume | No |
| Board theme | Red / green / blue | No |
| Tap haptic | Vibration toggle | No |
| Screen orientation | Portrait or landscape preference | No |
2.3 Local game progress
The App also stores on-device only progress so you can resume after relaunch:
| Data | Purpose | Uploaded |
|---|---|---|
| Per-tier board snapshots | Resume unfinished puzzles (grid state, elapsed time, selection) | No |
| Last played tier | Open the tier you were playing | No |
| Max unlocked tier | Remember unlock progress | No |
These are local game-state fields, not cloud saves, and are not used to identify you. Clearing app data or uninstalling removes settings and progress.
