American Mahjong Academy is a free American mahjong game for Mac, iPad and iPhone. It collects no personal data, has no analytics, runs no trackers, and contains no advertising. There is no user account to create. The full game is available offline.
The sections below describe what little data is involved in normal operation, and where to reach us if you have questions.
Nothing. American Mahjong Academy does not collect, store, or transmit any personal information about you. We have no servers. We have no databases. We have no record of who installs the app, where, or how it’s used.
The app integrates with two Apple services. When you use them, Apple’s privacy practices apply, not ours. We never see this data.
If you choose to play online turn-based matches, the app uses Apple’s Game Center to find opponents and synchronize match state. Game Center is operated by Apple. By signing in, you consent to Apple’s handling of your Game Center data per the Apple Privacy Policy.
You can play the entire single-player experience and Local Network play without ever signing in to Game Center.
The app includes three optional consumable tip products ($0.99 / $2.99 / $9.99). These tips do not unlock any features — the app is free with no paywall. If you choose to leave a tip, the purchase is processed entirely by Apple’s App Store / StoreKit. We never see your name, email, billing information, payment method, or transaction details.
Apple may share aggregate sales reports with us (e.g. “10 small tips this month”); these reports never identify individual purchasers.
Your in-progress game and points are stored locally on your device, inside the app’s sandbox container. They are never transmitted off your device.
If you use the Local Network feature, American Mahjong Academy announces itself on
your local Wi-Fi via Bonjour (_amj-academy._tcp) so other people running
the app on the same network can find your game. Game data is exchanged
directly between devices on your network — no servers are involved, and nothing
is sent to us or to Apple.
Your device will prompt you for permission the first time the app uses local network discovery. You can decline; LAN play will be unavailable, but every other feature still works.
American Mahjong Academy is rated 4+ and is appropriate for users of all ages. We do not knowingly collect any data from anyone, including children under 13. If you are a parent or guardian and have questions, please contact us at the email below.
The tile artwork bundled with the app is from the FluffyStuff/riichi-mahjong-tiles project, released under CC0 1.0 Universal (Public Domain Dedication). No data about your use of the artwork is collected or transmitted.
Because we collect no personal data about you, there is nothing for you to access, correct, port, or request deletion of from us. If you have questions about Game Center data, please contact Apple. If you have questions about purchase history, please refer to your Apple ID account.
If we ever change the app in a way that affects privacy (for example, adding analytics), we will update this page and post a clear notice in the app before the change takes effect. The Last updated date at the top of this page will reflect the most recent revision.
