Privacy Policy

• Account Information: If you create an account, we may collect your email address, username, and account credentials.
• Gameplay Data: To provide game analysis, hand suggestions, and statistics, we process local game state data (e.g., tile hands, tile selections, and move histories).
• Device & Usage Analytics: We collect standard technical information such as device type, operating system version, app diagnostics, and anonymized performance metrics to improve app stability.

We use the collected data strictly to:

• Provide, operate, and maintain game engine functionality.
• Calculate hand proximity, bot decision-making, and tile matching suggestions.
• Improve software features and resolve technical bugs.
• Respond to customer support requests.

Where possible, game hand processing and tile pattern calculations are performed locally on your device. We do not sell, rent, or trade your personal data or gameplay history to third-party advertisers.

We may use trusted third-party service providers for hosting, crash reporting, and analytics (e.g., Apple App Analytics, Google Play Console, or Cloud Hosting). These parties access data only as necessary to perform support tasks on our behalf.

You may request access to, correction of, or deletion of your personal account data at any time by contacting us at support@rosemahjong.app.

If you have questions about this Privacy Policy, please contact us at support@rosemahjong.app.
