Privacy Policy

Last updated: March 26, 2026

This Privacy Policy describes how Mine Master ("we", "us", or "our") collects, uses, and shares information when you use our mobile application (the "App"). By using the App you agree to the practices described in this policy.

1. Information We Collect

We collect the following information when you register and play:

• Account data: username, email address, password (stored as a secure hash), and country.
• Game data: scores, completion times, winning streaks, hints used, and level progress.
• Device data: internet connectivity status, needed to sync your progress and display leaderboards.

If you choose to sign in with Facebook Login, we receive your Facebook ID, display name, and (optionally) email address from Facebook in accordance with the permissions you grant. We do not receive or store your Facebook password.

2. How We Use Your Information

• Create and authenticate your account.
• Save and sync your game progress across sessions and devices.
• Display leaderboards and your rank among other players.
• Provide customer support if you contact us.

We do not use your data to serve advertisements, build advertising profiles, or sell your information to third parties.

3. Data Stored on Your Device

The App stores authentication tokens, your username, email, and cached game data locally using SharedPreferences and Hive (an encrypted local database). This enables offline play and faster load times. You can clear this data at any time by uninstalling the App.

4. Data Shared With Third Parties

• Our backend server: Game results, scores, and account data are transmitted to our servers to power leaderboards and persistent progress.
• Meta (Facebook): If you use Facebook Login, authentication is handled through the Facebook Login SDK. Meta's data practices are governed by the Meta Privacy Policy.

We do not share your personal data with any other third parties.

5. Data Retention

We retain your account and game data for as long as your account is active. You may request deletion of your account and associated data at any time by contacting us at the address below. We will process deletion requests within 30 days.

6. Children's Privacy

The App is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us and we will promptly delete that data.

7. Security

We use industry-standard measures (HTTPS for data in transit, hashed passwords, encrypted local storage) to protect your information. No method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

8. Your Rights

Depending on your location, you may have the right to:

• Access the personal data we hold about you.
• Request correction of inaccurate data.
• Request deletion of your data.
• Object to or restrict certain processing.

To exercise any of these rights, contact us using the details below.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes by updating the "Last updated" date at the top of this page. Continued use of the App after changes constitutes acceptance of the revised policy.
