Google Analytics

On the basis of our legitimate interests in the optimization and analysis of our online offering as defined in Art. 6 para. 1 lit. f. of the GDPR, this website uses the "Google Analytics" service, which is provided by Google Inc.

IP anonymization is used on this website. User IP addresses are shortened within the member states of the EU and the European Economic Area and in the other states party to the agreement. In isolated cases only, the IP address is initially transmitted in full to a Google server in the USA and abbreviated there. This abbreviation eliminates the personal reference of your IP address. The user IP address transmitted by the browser is not combined with other data stored by Google.

Google AdWords and Google Conversion Tracking

Our website uses Google AdWords. The provider is Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States.

AdWords is an online advertising program. Conversion tracking is part of our online advertising program. When you click on an ad placed by Google, a cookie is placed for conversion tracking. Cookies are small text files that your web browser stores on your end device. Google AdWords cookies become invalid after 30 days and do not personally identify users. The cookie tells Google and us that you have clicked on an advertisement and been redirected to our website.

Every Google AdWords customer receives a different cookie. The cookies cannot be traced via the websites of AdWords customers. Conversion cookies are used to generate conversion statistics for AdWords customers who use conversion tracking. AdWords customers can find out how many users clicked on their ad and were redirected to pages with conversion tracking tags. However, AdWords customers do not receive any information that allows them to personally identify users. If you do not wish to participate in tracking, you can object to its use. Simply disable the conversion cookie in your browser’s user settings. This information is then not included in the conversion tracking statistics.

The storage of "conversion cookies" is based on Art. 6 para. 1 lit. f of the GDPR. As website owners, we have a legitimate interest in analyzing user behavior in order to optimize our website and advertising.

For details about Google AdWords and Google conversion tracking, please see the Google Privacy Policy:

Modern web browsers allow you to monitor, restrict or prevent the placement of cookies. Disabling cookies may reduce the functionality of our website.
