Welcome to Guandan Score (the “App”). The App is provided by independent developer Taiyi Wang (“we”). It helps you record finish order, ranks, and tribute notes in offline Guandan games. Please read this policy before use.
1. Information we collect
The App does not require an account, does not run our own servers, and does not upload your game data to a backend we operate.
The following stays on your device:
- Player names you type — shown on seats and in tribute notes.
- Game scoring records — seats, finish order, ranks, Ace-out, and elapsed time.
- Trial and purchase status — for example when a 1-month trial started, and entitlements reported by the system.
We do not collect government IDs, contacts, precise location, photos, microphone audio, or advertising identifiers.
2. How this information is used
- Only to score games, show results, and resume an unfinished session on this device.
- Not for advertising profiles, sale to third parties, or marketing unrelated to the App.
3. In-app purchases
The App offers a 1-month trial, monthly subscription, yearly subscription, and lifetime unlock. Payment, receipt validation, refunds, and subscription management are handled by Apple through the App Store / StoreKit. We cannot see your card number, Alipay/WeChat account, or Apple ID password.
You can view or cancel monthly and yearly subscriptions in Settings → Apple ID → Subscriptions on iPhone or iPad.
4. Permissions and system APIs
- The App uses on-device storage (UserDefaults) so games and trial state persist between launches.
- The App does not request tracking permission (App Tracking Transparency) and does not track across apps.
5. Third-party services
Besides Apple’s App Store, StoreKit, and system services, the App currently includes no analytics, ads, push, or social-login SDKs. If that changes, we will update this policy.
6. Storage and deletion
Data lives on your device. Uninstalling the App, or deleting its data in system settings, removes those local records. We cannot remotely restore or delete data on your device.
7. Children
The App is an offline scoring tool. It does not offer online play, gambling, or cash prizes. We do not knowingly collect personal information from children under 13. If you are a minor, please use the App with a parent or guardian’s consent.
8. Updates
If this policy changes in a material way, we will update the “Last updated” date here and provide the latest text in the App. Continued use means you understand the updated policy.
