Guandan Drill Privacy Policy
This Privacy Policy describes how Guandan Drill (the "App") handles your information. The App creates no account of its own, does not ask for a phone number, and does not upload card photos, drill records or scores. Purchases and restores use the payment provider’s account.
Camera and photo library
Used only to recognize the cards in your hand. Recognition runs on your device. Photos never leave the device and are not saved outside the App.
Drill records, scores and settings
Stored only on your device. Deleting the App removes them entirely.
Purchases
iOS purchases use the Apple App Store. Android and HarmonyOS builds with Huawei payment use Huawei payment. The provider processes the information needed for sign-in, transaction verification and restoration under its own privacy rules. We do not receive payment credentials such as bank card details. The App stores verified purchase status locally. Your consent is requested before first connecting to Huawei payment.
Network
Network access is used for product queries, purchase verification and restoration through the applicable payment service. The App has no ads or analytics. Help, privacy and social links you choose to open are handed to your browser or the applicable app.
Children
The App does not ask children to provide personal information. Payment services apply their own account and children’s privacy rules.
