Push notifications
The Mathekiste app uses push notifications to inform users about new content or important information. These notifications are delivered via the OneSignal service (OneSignal, Inc., 2850 S Delaware St Suite 201, San Mateo, CA 94403, USA).
A so-called device token is created and transmitted to OneSignal. This token is an anonymous device identifier that is required to deliver push messages to the respective end device. OneSignal also stores technical information such as language, time zone and app version. Personal data such as name or email address is not collected or stored.
This data is processed on the basis of your consent (Art. 6 (1) (a) GDPR), which you can give when you first start the app by answering ‘Allow notifications?’ You can deactivate push notifications at any time in your device’s system settings.
