Privacy Policy

Effective Date: July 29, 2026

1. Information We Collect

To provide and improve our Mahjong app ("App"), we collect the following categories of information:

• Account Information: We collect your email address and display name (from your Firebase Auth or Apple ID login) to create your account, manage access, and distinguish you from other players.
• Gameplay Data: We collect and track your past game scores, daily challenge histories, and daily/monthly leaderboard records to calculate rankings and display game analytics.
• Device and Advertising Identifiers: We and our third-party advertising partners automatically collect mobile advertising IDs (such as Apple's IDFA or Google Advertising ID) and device characteristics to deliver advertisements.

2. How We Use Information

We use the data we collect for the following specific purposes:

• To verify your identity and maintain your access to the App.
• To run and manage global daily and monthly leaderboards.
• To track your individual gameplay histories and daily challenges.
• To serve and personalize advertisements through our advertising partners.

3. Data Sharing and Third-Party Services

We do not sell your personal information. However, we do partner with third-party service providers to facilitate app operations and monetize our services:

• Google AdMob: We use Google AdMob to serve banner and interstitial ads. AdMob may collect and use device identifiers, location data, and app usage metrics to serve targeted, personalized, or non-personalized advertisements. You can review Google's Privacy Policy for more details.
• Firebase (Google LLC): We use Firebase for backend cloud hosting, user authentication, and real-time database management.

4. App Tracking Transparency (ATT) and Tracking Disclosures

For iOS users, our App complies with Apple’s App Tracking Transparency framework. If you consent to the ATT prompt, our advertising partners (Google AdMob) will track your activity across other apps and websites to serve personalized advertisements. If you opt-out, we will only serve non-personalized ads, though your device ID may still be used for frequency capping and fraud prevention.

5. Data Retention and Deletion

We store your account profile, gameplay statistics, and leaderboard rankings as long as your account remains active. If you wish to delete your account and wipe your associated database records (including your user profile, daily challenge histories, and leaderboard entries), you can request deletion by contacting us at the email address provided below.

6. Security

We use industry-standard security measures to safeguard your information in our cloud databases. However, please note that no method of electronic storage or transmission over the internet is completely bulletproof.

7. Your Rights

Depending on your geographic location (such as the EU or California), you may have the right to access, update, or request the absolute deletion of your personal data. To exercise any of these privacy rights, please submit a request to our support email.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be published directly on this page with an updated "Effective Date."
