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.
