Timetable · Principal · Privacy Policy
1. What we collect
Nothing. The app has no account system, requires no sign-up or login, and includes no analytics, advertising, crash reporting or third-party SDKs.
2. Where your data lives
The timetables, classes, teachers, subjects, classrooms and period settings you enter, plus the school name and logo you choose, are stored in the app sandbox on this device and never leave it.
Deleting the app removes this data with it, and you can delete individual timetables, lists or their contents inside the app at any time.
3. Network and permissions
The app sends data to no server. It talks to Apple only through StoreKit, when checking subscription status, making a purchase or restoring purchases.
It asks for no sensitive permissions such as location, camera, photo library, contacts or microphone. The logo picker uses the system photo picker and reads only the image you choose — the app cannot see anything else in your library.
4. Membership and payment
Memberships are sold as Apple in-app purchases; payment, renewal and refunds are all handled by Apple. We never receive your name, card or Apple ID details — only whether an active subscription exists.
You can cancel at any time under Settings ▸ Apple ID ▸ Subscriptions.
5. Sharing with third parties
Because we collect nothing, there is no personal information to provide, transfer or disclose to third parties; purchase-related data is handled by Apple under its own privacy policy.
6. Children's privacy
The app is aimed at teachers and school administrators and collects no personal information (including children's personal information), in line with applicable rules on protecting minors' data.
7. Changes to this policy
If this policy changes we will publish the new version on this page and update the effective date.
