Please be aware that the transmission of data over the Internet (e.g. when communicating by e-mail) may not be entirely secure. It is not possible to fully protect data from third-party access.
The use by third parties of contact data published due to the obligation to provide a legal notice for the purpose of the transmission of advertising and informational materials that have not been explicitly requested is hereby explicitly rejected. The operators of this site expressly reserve the right to take legal action in the event of the sending of unsolicited marketing information, for example via spam e-mails.

The functions of the Twitter service are integrated into our website. These functions are offered by Twitter Inc., 795 Folsom St., Suite 600, San Francisco, CA 94107, USA. The use of Twitter and the “Retweet” function links websites visited by you to your Twitter account and makes this known to other users. This also entails the transmission of data to Twitter.
