In order to make this possible, these third parties must receive the IP address of each user of our website. Without transmission of the IP address, it is not possible to make content available to the respective user, so this is required data.

We use content from third parties as follows:

  • Google Maps – In our offers, maps from the service "Google Maps" (provider: Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA) are embedded via iFrame.
