Furthermore, we set cookies that remain stored in your browser for a longer period of time. These cookies give us information about your preferences when using our site and store, for example, your language setting.

Website analysis

We collect information about when and how often you use our website and which sub-pages you visit to make our website more interesting to you. For this purpose we use Google Analytics.

The program Google Analytics is provided by Google LLC, 1600 Amphitheatre Parkway, Mountain View CA 94043, USA (“Google”). It stores so-called cookies on your computer, i.e. small text files through which the program can recognize your computer every time you visit our website. This may collect information about your usage habits, including your IP address.

This information is transferred to a Google server in the USA and stored there. However, your IP address is shortened (“IP masking”), so that an individual assignment to you is no longer possible. Only in exceptional cases IP addresses can be transferred to the USA and then shortened there. Google assures that this data will not be merged with other data that Google may have about you. We have concluded an order processing agreement with Google for this purpose.

You can exclude the storage of cookies in your browser settings and delete existing cookies. This also applies to Google Analytics cookies. If your browser does not allow cookies, you can visit our website anonymously.

If you wish to prevent Google Analytics from collecting, processing and storing your data without blocking our other cookies, you can install a tool from Google on your computer, which you can download from the following link: This is an extension (so-called add-on) to your browser.

Google Analytics will delete the data collected in this way if it is no longer required for the purposes of analyzing our website through statistical evaluations. This is the case after 14 months at the latest.

The legal basis for this data processing is Art. 6 (1) lit. f GDPR. Our legitimate interest is to continuously analyze and improve our website in order to reach as many interested parties as possible.

YouTube videos

We embed YouTube videos on some of our websites. The corresponding plugin is provided by YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA.

Once you open a page with an embedded YouTube video, a connection to YouTube’s servers is established. YouTube is informed about which website you are currently visiting. YouTube can associate this information with you personally and link it to other data if you have a YouTube account and are logged in to it. If you would like to prevent this data transfer, we recommend that you log out of your YouTube account.

Further information on data protection at “YouTube” can be found in the provider’s data protection declaration at:

For our part, the transfer of data to YouTube is based on Art. 6 (1) lit. f GDPR. We have a legitimate interest in making our site more interesting and attractive through embedded videos.
