Privacy Policy
Overview
This Privacy Policy describes how your personal information is handled in Must Ring (必达) for iPhone.
Information we collect
Must Ring has no account, no sign-in and no server. Your must-rings, settings and ring record are stored on your device and shared only between the app and its widgets. We do not collect, use, save, or have access to any of it.
Purchases
Must Ring Pro is a one-time purchase processed by Apple. Apple handles your payment details — we never see them.
Must Ring uses RevenueCat to validate the purchase and restore Pro. RevenueCat receives your purchase history (which product you bought and when) and a random, anonymous app user ID generated by the app. This is the only data that leaves your device. It is used only to unlock Pro, is not linked to your name, your email or your Apple ID, and is not used for tracking or advertising.
Analytics and advertising
Must Ring contains no advertising SDK and no analytics SDK that tracks your usage. No usage data, no device identifiers and no location data are sent anywhere. Apart from the purchase check above, the app makes no network requests.
Notifications and permissions
AlarmKit, notification and contact access are used only to make must-rings work on your device. Contact access is read-only: nothing is ever written back to your contacts.
Our Applications Comply with the Children's Online Privacy Protection Act
Our applications don't collect personal information from anyone, including children under the age of 13. The anonymous purchase record described above identifies no one.
