This Privacy Policy applies to the Mahjong Solitaire mobile application (Package Name: com.nimtrilabs.mahjong_solitaire) developed and operated by Nimtri Labs ("we", "our", or "us").

We are committed to protecting your privacy. This policy outlines how your information is handled when you play our game.

1. Information We Do Not Collect

We do not require account registration, login, or any personally identifiable information (PII) to play Mahjong Solitaire. We do not collect:

• Names, email addresses, phone numbers, or physical addresses.
• Biometric, financial, or payment information.
• Precise GPS location data.
• Contacts, microphone, camera, or file contents.

2. Data Stored Locally on Your Device

To provide a smooth puzzle experience, Mahjong Solitaire saves game state information locally on your device using standard local preferences storage:

• Level Progress & Scores: Completed levels, high scores, stars earned, and unlocked puzzle maps.
• Gameplay Settings: Sound effects volume, background music preferences, vibration/haptic feedback settings, and selected themes/skins.
• Daily Challenge Stats: Daily calendar completions and streak counters.

This data remains strictly on your device and is never uploaded to our servers.

3. Third-Party Services & Advertising (Google AdMob)

Mahjong Solitaire is a free-to-play game supported by advertising. We integrate Google AdMob (a service provided by Google LLC) to display non-intrusive banner, interstitial, and rewarded ads.

Google AdMob may collect and process pseudonymous device identifiers, such as:

• Google Advertising ID (GAID) / Apple IDFA.
• Device information (device model, operating system version, screen resolution).
• IP address (for coarse geographic location to serve localized ads and prevent fraud).
• Ad interaction metrics (ad views, clicks).

We configure AdMob with family-friendly and General Audience (PEGI 3 / Everyone) content filters.

For more details on how Google processes and protects advertising data, please review:

• Google Privacy Policy
• How Google uses information from sites or apps that use our services

4. Device Permissions

The App requests only the minimum necessary permissions required for core functionality:

• android.permission.INTERNET: Required to connect to Google AdMob servers to retrieve advertisements.
• android.permission.VIBRATE: Used exclusively to provide tactile haptic feedback during tile selections and matches.
• com.google.android.gms.permission.AD_ID: Standard Google Play Services permission to support ad delivery.

5. Children's Privacy (COPPA & GDPR-K)

Mahjong Solitaire is suitable for general audiences and all ages. We do not knowingly collect personal identifiable information from children under the age of 13 (or under 16 in the European Union). If you believe a child has provided personal information to third-party services through our app without parental consent, please contact us and we will take appropriate steps.

6. Your Rights and Data Deletion

Because all gameplay data is stored locally on your device, you have complete control over your data at all times:

• Clear Progress: You can reset or delete all game progress by clearing the app's cache/storage in your device's Settings > Apps > Mahjong Solitaire > Clear Storage.
• Uninstall: Uninstalling the application completely deletes all locally saved game files.
• Opt-Out of Personalized Ads: You can reset or limit your advertising identifier in your device settings (Settings > Google > Ads > Delete or Reset advertising ID on Android, or Settings > Privacy > Tracking on iOS).

7. 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 "Last Updated" date. We encourage you to review this page periodically for any changes.
