Liability for Content

As a service provider we are responsible, according to § 7 1 TMG, for our own content on these pages under the general laws. According to §§ 8 to 10 TMG we are not obligated as a service provider to monitor transmitted or stored information, or to investigate circumstances that indicate illegal activity. Obligations to remove or block the use of information under the general laws remain unaffected. However, a relevant liability is only contingent from the date of knowledge of a specific concrete infringement. Upon notification of such violations, we will remove the content immediately.

Liability for Links

Our site contains links to external websites, over which we have no control. Therefore we cannot accept any responsibility for their content.

No illegal content was distinguishable at the time of linking. A permanent control of the linked pages is unreasonable without concrete evidence of a violation. Upon notification of violations, we will immediately remove such links.
