Additional guidance on use of our apps

This section concerns data processing when using our apps. In all other cases, our Data Privacy Statement applies. 

If you download one of our apps from an App Store, the necessary information will be transmitted to the App Store, in particular username, email address and the customer number of your account, as well as the time of the download. We only process the data to the extent required to download the app onto your mobile terminal device. If you do not download the app from the App Store, but from our website instead, other user data is processed, as explained in the Data Privacy Statement. 

When you use our apps, we process the technically required data to provide the functions of the app and to guarantee the necessary stability and security. The legal basis is our legitimate interest. Specifically this concerns: IP address, date and time of the request, time zone difference compared with Greenwich Mean Time (GMT), content of the request (site visited), access status/HTTP status code, data volume transmitted, previous site visited, browser, operating system, language and browser software version. 

Depending on the provider of your device, your device marking, the IMEI number (International Mobile Equipment Identity), the unique number of the network subscriber, the IMSI number ( International Mobile Subscriber Identity), the mobile phone number (MSISDN), the MAC address for wifi use, the name of your mobile terminal device and your e-mail address may be collected when providing the services of the app. We do not collect this data, but would like to point it out to you anyway.

In addition to the data mentioned above, technical aids and various functions may be deployed when you use our mobile app, particularly cookies, which may be stored on your terminal device. You can control this via the cookie banner of the app.
