Privacy Policy
Last updated: July 11, 2026
Our Commitment to Privacy
Mahjong is designed to be simple, fast, and respectful of your privacy. We believe you shouldn't have to trade your personal data just to play a game.
What We Collect
Nothing. We do not collect, store, or process any personal data. There are no user accounts, no sign-ups, and no forms that ask for your information.
Local Storage
Mahjong uses your browser's localStorage to save:
- Your high score and best time
- Your theme preference (dark or light mode)
- Your cookie consent preference
This data stays entirely on your device — it is never transmitted to our servers or any third party. You can clear it at any time through your browser settings.
Cookies
We do not use any tracking cookies, advertising cookies, or third-party cookies. The only cookie-like mechanism is localStorage (described above), which is purely functional — it keeps your high score and settings consistent between visits.
Third-Party Services
We do not use any third-party analytics, advertising networks, or tracking services. There are no embedded social media widgets, no analytics scripts, and no external content that could track your activity.
Children's Privacy
Mahjong is suitable for all ages. Since we collect no personal information from anyone, the game is safe for children to play without any privacy concerns.
Changes to This Policy
If our privacy practices ever change, we will update this page. However, our core commitment — no personal data collection, no tracking — will always remain.
