This policy applies specifically to Mahj Coach, an app from Ylemos Inc. It is a product-specific notice and supplements the Ylemos company privacy policy.
2. Information in Mahj Coach
Mahj Coach does not collect or transmit personal information. It does not require an account and has no advertising, analytics services, tracking, third-party software development kits, or developer-operated backend.
Your lesson progress, practice games and game reviews, hands you type in from your own card, display and sound settings, and simple counts of how often you use features such as lessons and reviews are stored in the app's private storage on your device. Mahj Coach does not send this information to Ylemos Inc or to other parties.
When you turn on spoken tile names, the names are read aloud by your device's built-in speech feature.
3. Purchases
Mahj Coach offers a one-time in-app purchase. Payment is handled entirely by Apple. Ylemos Inc does not receive your payment details, name, or Apple Account information. The app checks with Apple on your device to confirm whether the purchase is active.
4. Children's privacy
Mahj Coach is designed for adults learning the game and is not directed to children. The app does not ask anyone to provide personal information and does not collect or transmit personal information from any user, including children.
5. Email support
If you choose to email support, Ylemos Inc receives your email address and the information included in your message so we can respond.
6. Apple services
Apple may process information through iOS or the App Store, such as purchase status, crash reports, or App Store analytics, under Apple's own privacy terms and your device settings. This processing is separate from Mahj Coach's on-device records; Mahj Coach does not send those records to Ylemos Inc.
