Privacy Policy

Last updated: July 10, 2026

Our Commitment to Privacy

Mahjong Online is designed with privacy as a priority. Our game runs entirely within your web browser —we do not collect, store, or process any personal data. There are no user accounts, no sign-up forms, and no tracking scripts.

Information We Do Not Collect

• Personal Information: We do not collect names, email addresses, phone numbers, or any other personal identifiers.
• Location Data: We do not track your geographic location.
• Usage Analytics: We do not use third-party analytics or tracking services.
• Device Information: We do not collect information about your device, browser, or operating system.

Local Storage

Our website uses your browser's localStorage feature to save your preferences locally on your device. This includes:

• Theme preference (light or dark mode)
• High score (for your personal reference)

This data never leaves your device. It is not transmitted to our servers or any third party. You can clear this data at any time through your browser settings.

Cookies

We do not use advertising cookies, tracking cookies, or third-party cookies. The only cookie-related feature is a minimal notification acknowledging our use of localStorage for theme preferences.

Third-Party Services

We use Google Fonts to serve the Playfair Display typeface. When your browser loads this font, Google may receive standard HTTP request data (such as your IP address). Google Fonts privacy policy can be found at policies.google.com/privacy.

Children's Privacy

Our game is suitable for all ages. Since we collect no personal information, COPPA compliance is inherent in our design.
