### A. Local Game Data
Game progression data, including unlocked stages, earned stars, coins, high scores, lifetime statistics, and user settings (e.g., sound volume, haptic vibration, colorblind mode), is stored **locally on your device** via Android SharedPreferences. We do not transmit or store your local game progress on external servers.

### B. Automatically Collected Information (Third-Party Services)
The application utilizes third-party software development kits (SDKs) that may collect non-personally identifiable information automatically to provide advertisement services and ensure application stability.

These third-party services may collect:
- **Device Identifiers**: Advertising ID (GAID), Android ID, device model, manufacturer, and operating system version.
- **Usage & Diagnostic Data**: Ad interaction data, crash logs, and performance metrics.

Google AdMob uses these identifiers to serve relevant interstitial advertisements and perform ad frequency capping (e.g., displaying ads every 2 completed stages). For more details, please review [Google's Privacy & Terms](https://policies.google.com/privacy).
