Support
Short answers to what is asked most, and an address that reaches the developer, Orhan Ege Bilge, directly.
Where does my data live?
On your device. Your App Store Connect API key is stored in the iOS Keychain, on this device only, and is not synced to iCloud Keychain. Your reports come from Apple straight to the device and stay there. The developer never sees your key or your reports.
What does the bell service keep?
Nothing until you switch the bell on. Then it keeps your phone's push address and when it last registered, under a random code with no name and no email address, and for each route what it needs to ring it. It never sees your key, a report or a figure. The privacy policy lists all of it.
How do I remove the connection and delete the bell account?
Both are in the app's Settings. “Remove connection” deletes the key from the Keychain and asks whether to delete the stored reports as well. Switching the bell off removes this phone from the bell service. Erasing everything on the bell service deletes every phone and every route of the bell account and removes its code from this phone. Do this before you delete the app: deleting the app does not tell the bell service.
How do I restore a purchase?
Open the Tillroll Pro screen in the app and tap “Restore purchases”, signed in with the Apple Account that bought it. Tillroll Pro is sold by Apple; the app learns from Apple only whether the purchase is valid for you.
How do I cancel a subscription?
Subscriptions are billed and cancelled by Apple. Tap “Manage subscription” on the Tillroll Pro screen, or open the iOS Settings app, tap your name, then Subscriptions. Buying the lifetime purchase does not end a running subscription: cancel it separately.

Include your iPhone or iPad model, the iOS and app versions, and the steps that led to the problem. Do not send your API key, a .p8 file or the bell account's code.
