MinMen Studio ("we", "us", or "our") operates the DragonFish mobile application (the "App") on iOS and Android. This Privacy Policy explains what information is collected when you use the App, how it is used, and your choices regarding that information.
1. Information We Collect
DragonFish keeps core training and analysis data on your device whenever possible. This includes local game positions, move history, settings, and app preferences.
If you sign in, we may receive basic account information from the sign-in provider, such as your user ID, display name, email address, and profile photo. We use this to sync purchases, hearts, online play, and account-based features.
- Online play data — match records, move history, ratings, statistics, and basic profile information needed to run online games.
- App diagnostics — crash reports, performance information, and limited usage events that help us find bugs, improve reliability, and prevent abuse.
- Purchases and entitlement data — product ownership, hearts balance, and VIP/unlimited status. Payment processing is handled by Apple or Google; we do not receive your card or payment details.
2. Board Recognition and Overlay Analysis
Some DragonFish features can recognize a Xiangqi board from a photo or from a screen area selected by you. Images are used only to identify the board position for analysis. We do not store those images or use them outside the App. On Android, the Overlay feature requires explicit screen-capture permission and shows a foreground notification while it is running.
3. In-App Purchases
DragonFish offers optional in-app purchases, including hearts and VIP/unlimited access. On iOS, purchases are processed by Apple's App Store. On Android, purchases are processed by Google Play Billing. We do not receive or store your payment card or financial information. See Apple's Privacy Policy and Google's Privacy Policy for details on how each platform handles purchase data.
4. Acceptable Use
DragonFish is provided for learning, training, analysis, and personal study of Xiangqi. You are responsible for using the App in accordance with applicable laws, tournament rules, online platform rules, and fair-play expectations. MinMen Studio is not responsible for misuse of the App, including use in contexts where external assistance is prohibited.
5. Data Retention
Local device data is deleted when you uninstall the App. Account data, online play records, purchase entitlement records, and support messages are retained for as long as needed to provide the App, restore purchases, maintain fair play, meet legal obligations, and resolve support requests. You may request deletion of data associated with your account or device at any time — see Section 7.
6. Security
All data transmitted between the App and our cloud providers is encrypted in transit (HTTPS / TLS). Local data on your device is protected by your device's own security mechanisms. We limit access to operational data to what is needed to operate, secure, and improve the App.
7. Your Rights & Data Deletion
You may request access to, correction of, or deletion of data we hold that is associated with you. To make a request, email us at the address below with a description of your request. We will respond within 30 days. We may need information such as your account email or app identifier to locate the relevant records.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. Continued use of the App after any changes constitutes acceptance of the updated policy.
