4 Data protection and privacy provisions when using our app

4.1 Firebase Cloud Messaging

We use Firebase Cloud Messaging, a cross-platform messaging service, for our app. The service provider is the American company Google Inc. For the European region, the company Google Ireland Limited (Gordon House, Barrow Street Dublin 4, Ireland) is responsible for all Google services. Firebase also processes data of yours in the USA, among other places. The app uses the push services of the operating system manufacturers. These are short messages that can be sent directly through Firebase to the app from our server. Using this mechanism, changed content can be synchronized very quickly on all end devices. When using the push service, a device token from Apple or a registration ID from Google is assigned. These are encrypted, anonymized device IDs. The purpose of their use is solely to provide the push services. Firebase Cloud Messaging is part of the backend service platform. For more information on the terms of service of Firebase Cloud Messaging, please visit Firebase’s website:

4.2 Firebase Crashlytics

To be able to continuously improve the reliability and stability of our app, we are reliant on anonymized crash and problem reports. We use Firebase Crashlytics for this, which is a service of Google Ireland Ltd, Google Building Gordon House, Barrow Street, Dublin 4, Ireland.

In the event of a problem or crash, anonymized information is sent to Google’s servers in the USA (installation UUID, crash trace, cell phone manufacturer and operating system, last log messages, and app state at the time of the crash). This information does not contain any personal data.

Crash reports are only sent with your explicit consent. When using the app (Android or iOS), you can provide and withdraw consent in the app settings.The legal basis for the data transfer is Art. 6 para. 1 letter a of the GDPR.For more information on data protection, please see the data protection and privacy policy of Firebase Crashlytics at: and

By using these functions, you consent to the processing of the data you enter by the PONS API. The PONS API processes the data you enter to generate the requested translations and dictionary queries. For this purpose, the texts and search queries you enter are sent to the PONS API and processed there. The PONS API collects and stores this data for a limited time to be able to offer and improve its service. The PONS API also uses cookies and similar technologies to provide its services and analyze user behavior. This information is stored on servers within the European Union. For more information on data protection and the processing of your data by the PONS API, please see the PONS data protection and privacy policy at:
