The short version
Patter Call does not collect your data. There are no accounts, no analytics, no advertising and no third-party tracking of any kind. Every puzzle, every call and your entire caller's card run on your device and stay there. This policy explains exactly what the app touches and why.
Data we collect
None. Patter Call does not transmit any personal data to us or to anyone else. Nothing you do inside the app — solving a floor, building a call sequence, naming your caller card — leaves your device.
What the app stores, and where
| Information | Stored where | Leaves the device? |
|---|---|---|
| Floor results, stars, shortest call sequences, attempts | On-device (SwiftData) | No |
| Club Night history and streaks | On-device (SwiftData) | No |
| Starred calls in the Call Book | On-device (UserDefaults) | No |
| App settings (sound, music, haptics, appearance) | On-device (UserDefaults) | No |
| Caller card: display name, home club, badge photo | On-device (SwiftData) | No |
Camera and photo library
Patter Call asks for camera access only if you choose "Take a photo" while setting up your caller badge, and for photo library access only if you choose "Choose a photo" using Apple's system photo picker. In both cases, only the single photo you pick is used; it is resized and stored on your device for your caller badge and is never uploaded anywhere.
Notifications
If you turn on the optional Club Night reminder, Patter Call schedules a local notification directly on your device for the evening before your chosen club night. This does not involve a server, a push provider or any account, and it can be turned off at any time in Settings.
Third-party services
Patter Call includes no third-party analytics, advertising or software development kits, and makes no network requests for its puzzles, Call Book content or your saved progress. The app works fully offline.
Children's privacy
Patter Call does not knowingly collect any information from anyone, including children, because it collects no information at all. The app is not directed at children and contains no chat, social features or advertising.
Your choices
- Camera and photo library access can be revoked at any time in your device's Settings app.
- Notifications can be turned off at any time in your device's Settings app or inside Patter Call's own Settings screen.
- All progress — stars, badges, streaks and your caller card — can be erased at any time using Reset Progress in Settings.
- Deleting the app removes everything Patter Call has stored, since none of it exists anywhere else.
