SSL and TLS encryption
For security reasons and to protect the transmission of confidential content that you send to us as a site operator, our website uses an SSL or TLS encryption. Thus, data that you submit via this website is not readable for others. You will recognize an encrypted connection in the "https: //" address bar of your browser by the lock icon in the browser bar.

Google AdWords and Google Conversion Tracking
Our website uses Google AdWords. Provider is Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States.

AdWords is an online advertising program. As part of the online advertising program, we work with conversion tracking. After clicking on an ad displayed by Google, a cookie is set for conversion tracking. Cookies are small text files that your web browser stores on your device. Google AdWords cookies lose their validity after 30 days and are not used for personal identification of users. Using the cookie, Google and we recognize that you clicked on an ad and were redirected to our site.

Each Google AdWords customer receives a different cookie. The cookies are not traceable through AdWords client websites. Conversion cookies are used to generate conversion statistics for AdWords advertisers who use conversion tracking. Adwords customers learn how many people clicked on their ad and were redirected to conversion tracking tag pages. However, AdWords advertisers are not provided with information that allows them to personally identify the user. If you do not want to participate in the tracking, you can object to a use. To do so, the conversion cookie in the user settings of the browser must be disabled. Then there will be no inclusion in the conversion tracking statistics.

The storage of "conversion cookies" is based on Art. 6 (1) lit. f  GDBR. We as website operators 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, see the Google Privacy Policy:
