No Data Collection

Glaslabor Booking does not collect, store, or transmit any personal data to the developer or to third parties.

The app has no networking code and communicates with no server. The five bookable courses are embedded in the app; booking works entirely offline.

Bookings on Your Device

Your bookings are stored locally on the device using SwiftData. They never leave the device and are removed when you delete the app.

Calendar

With your permission the app adds booked courses as events to your calendar. iOS asks for calendar access for this. The app only creates events; it does not read, store, or transmit calendar content. You can revoke the permission at any time in iOS Settings.

Notifications

If you wish, the app reminds you one day before the course. These reminders are scheduled locally on the device; no push service is used.

No Analytics or Advertising

The app contains no analytics SDKs, advertising libraries, tracking pixels, or similar technologies. No user tracking takes place.

Apple App Store

The app is distributed via the Apple App Store. Apple may collect device-related data under its own privacy policy, available at: apple.com/privacy
