Liability for content

The site operator assumes no liability for information transmitted or stored by third parties. An obligation to monitor this information does not exist on the part of the site operator. If unlawful information is transmitted or stored by third parties, the site operator is only liable if he does not comply with a legitimate request to delete the information. Obviously illegal information will be deleted immediately after becoming known.

Liability for links

The site operator has no influence on external links. Before the publication of the links on these pages, these were checked to a reasonable extent for compliance with the legal provisions. The site operator is not responsible for changes resulting from the pages accessible via external links. In particular, a continuous control of external links to violations is not reasonable. Insofar as the site operator is informed of illegal content that can be accessed via external links, he immediately removes these links.


The copyright to all retrievable on the pages of the operator texts and multimedia content is owned by the site operator, as far as divergent copyrights are not shown separately. If the copyrights of third parties are not shown, a message via e-mail is requested. The site operator will remove such content immediately. The processing, distribution and duplication of content is not permitted without the explicit consent of the site operator.
