# Privacy Policy for Quadrille
**Last updated:** October 27, 2026
[Your Name / Studio Name] ("we", "our", or "us") operates the Quadrille mobile application (the "App"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App.
### 1. Information Collection and Use
Quadrille is designed to be played without creating an account. We do not ask for or collect your name, email address, phone number, or physical address.
#### A. Data Stored Locally on Your Device
- **Game Progress & High Scores:** Your board layout, streak, lifetime statistics, and theme preferences are stored locally on your device using Android Jetpack DataStore. This data never leaves your device unless backed up by your operating system's standard backup service (e.g., Google Drive backup).
#### B. Third-Party Services & Automated Data Collection
The App integrates trusted third-party SDKs to provide analytics, crash reporting, game achievements, and advertising. These services may collect device identifiers and usage metrics:
1. **Google AdMob & User Messaging Platform (UMP):**
- Serves banner and interstitial advertisements.
- May collect your device's Advertising ID (AAID), coarse location (country/city), and app interaction metrics to deliver relevant ads.
- For users in the European Economic Area (EEA), UK, and Switzerland, Google UMP requests your consent before serving personalized advertisements.
- [Google AdMob Privacy Policy](https://policies.google.com/privacy)
2. **Google Play Games Services:**
- Provides optional sign-in to sync game achievements and leaderboards.
- Handled directly by Google Play Services under your Google Account.
- [Google Play Services Privacy Policy](https://policies.google.com/privacy)
3. **Firebase Crashlytics & Analytics:**
- Collects diagnostic information when the App crashes (stack traces, device model, operating system version).
- Helps us identify and fix bugs to improve stability.
- [Firebase Privacy Policy](https://firebase.google.com/support/privacy)
### 2. Children's Privacy
Our App does not knowingly collect personally identifiable information from children under the age of 13. If you believe that your child has provided us with personal information, please contact us so that we can take necessary actions.
### 3. Data Retention and Deletion
Because game data is stored locally on your device, you can delete all your stored data at any time by clearing the App's storage via **Android Settings → Apps → Quadrille → Storage → Clear Storage** or by uninstalling the App.
### 4. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
