Our app uses Google Firebase technology (Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA, “Google”). Firebase is part of Google Cloud Platform and offers many services to developers. A list can be found here: Some Firebase services process personal information. In most cases, the personal data is limited to so-called “instance IDs”, which are provided with a time stamp. Firebase’s instance IDs are unique and thus allow the linking of different events or processes. These data are neither personally identifiable informations nor do we make any effort to personalize it afterwards. We process this aggregated data to analyze and optimize usage behavior and app functionality. We do not use Firebase services that use personally identifiable information, such as IP addresses, email addresses, telephone numbers or passwords.
