Privacy Policy

1. Overview & Data Philosophy

At MahjongOnline.co.uk, we believe in privacy by design. We do not require accounts, sign-ins, or passwords to play our free online Mahjong games. We do not collect names, email addresses, phone numbers, or credit card details.

2. Local Storage Usage

To ensure your game preferences and achievements are preserved between browser sessions, our website uses your browser's native LocalStorage strictly for:

• Saving your table theme preference (Emerald, Slate, Crimson).
• Saving your sound mute/unmute state.
• Storing local gameplay statistics (total games played, games won, fastest completion time, win streak).

This information is stored entirely on your local device and is never transmitted to our servers or sold to third parties.

3. Third-Party Advertising & Analytics

To keep this service free for everyone, we may display third-party advertisements (such as Google AdSense). These third-party vendors may use non-invasive cookies or web beacons to serve ads based on prior visits to websites. You can opt out of personalized advertising by visiting Google's Ads Settings.

4. UK GDPR & Data Protection

In accordance with the UK Data Protection Act 2018 and the UK General Data Protection Regulation (UK GDPR), you retain the right to clear your local data at any time directly through your web browser's "Clear Site Data" or "Clear Cookies" settings.
