Our websites use the functions of Google Analytics Remarketing in conjunction with the cross-device functions of Google AdWords and Google DoubleClick. The provider is Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.
This function makes it possible to link the advertising target groups created with Google Analytics Remarketing with the cross-device functions of Google AdWords and Google DoubleClick. In this way, interest-based, personalized advertising messages that have been adapted to you depending on your previous usage and surfing behavior on one end device (e.g. cell phone) can also be displayed on another of your end devices (e.g. tablet or PC).
If you have given your consent, Google will link your web and app browsing history to your Google account for this purpose. In this way, the same personalized advertising messages can be displayed on every device on which you sign in with your Google account.
To support this function, Google Analytics collects Google-authenticated user IDs that are temporarily linked to our Google Analytics data in order to define and create target groups for cross-device advertising.
You can permanently object to cross-device remarketing/targeting by deactivating personalized advertising in your Google account; follow this link to do so:

The summary of the data collected in your Google account is based exclusively on your consent, which you can give or revoke at Google (Art. 6 para. 1 lit. a GDPR). For data collection processes that are not merged in your Google account (e.g. because you do not have a Google account or have objected to the merging), the collection of data is based on Art. 6 para. 1 lit. f GDPR. The legitimate interest arises from the fact that the website operator has an interest in the anonymized analysis of website visitors for advertising purposes.
