Responsability for content

The content of our website has been assembled with the utmost care. However, we cannot assume any liability if the content contains any errors or omissions or is outdated. As a service provider, we are responsible for our own content on this website in accordance with the general statutory provisions under Section 7 (1) of the German Telemedia Act. Under Sections 8 to 10 of the German Telemedia Act, however, we are not under any obligation in our capacity as a service provider to monitor transferred or stored third-party information or to search for any evidence of illegal activity. This does not prejudice any obligations which may exist under general statutory provisions to remove or prevent the use of information. However, liability in this regard does not arise until we gain knowledge of a specific breach of the law. We will immediately remove the content concerned upon becoming aware of any such breaches. 

Liability for links

Our website includes links to external third-party websites on whose content we do not have any influence. For this reason, we cannot assume any liability for such third-party content. The provider or the website operator concerned is responsible for the linked content. The content concerned was reviewed for any breaches of the law at the time the link was created. There was no evidence of any unlawful content at the time the link was created. However, in the absence of any specific suspicion of a breach of the law, a continuous examination of the linked content is not possible. We will immediately remove the content concerned upon becoming aware of any such breaches.

We will immediately remove the content concerned upon becoming aware of any such breaches.
