Privacy Policy
Last updated: July 10, 2026
Our Commitment to Privacy
Mahjong Solitaire 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 or IP address.
- Usage Analytics: We do not use third-party analytics or tracking services.
- Device Information: We do not collect data about your device, browser, or operating system.
Local Storage
Our website uses your browser's localStorage feature to save preferences locally on your device only. 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 and contains no inappropriate content. Since we collect no personal information, COPPA and GDPR-K compliance is inherent in our design.
GDPR Compliance
Under the EU General Data Protection Regulation (GDPR), users have rights regarding their personal data. Since we do not collect, store, or process any personal data, there is nothing to access, rectify, or erase. Our service is fully compliant by design.
