The content of our website pages was created with great care. However, we can assume no liability for the correctness, completeness and topicality of the content. As a service provider, we are responsible for our own content on these pages under general law, as per § 7, Par. 1 of the TMG (German Telemedia Law).

Upon notification of such violations, we shall immediately remove the content in question.


Our site contains links to external websites over which we have no control. The provider or operator of the linked sites is always responsible for their content, therefore we cannot assume any responsibility for such third-party content. The linked sites were checked for possible legal violations at the time they were linked to our website. Illegal content was not apparent at the time the link(s) were created.
