Privacy Policy — 2-Player Mahjong (双人麻将)

Last updated: 30 July 2026 · Nexverse One

What we collect

Account. The app creates an anonymous account when you tap Play now. If you choose Sign in with Apple, we receive the identifier Apple provides and, if you share it, your email address (Apple lets you hide it behind a private relay address). We never see your Apple ID password.

Game data. When you play with a friend online, your moves, tiles, scores and room membership are stored on our servers (Google Firebase) so both players see the same game. Practice games against the computer are played entirely on your device.

Purchases. Subscriptions are processed by Apple. We use RevenueCat to check whether your account has an active subscription. We never see your payment details.

What we do not collect

No advertising identifiers, no location, no contacts, no tracking across other companies' apps or websites, and no analytics profiles. We do not sell data to anyone.

Where data lives and how long

Game and account data are stored with Google Firebase (United States). Finished game rooms are retained only for operating the service and may be deleted over time.

Your choices

You can sign out at any time in Settings. To ask for your account or game data to be deleted, email us at the address below and include the account email you used, and we will delete it.

Children

The app is not directed at children under 13 and does not knowingly collect personal information from them.
