Liability for content
Under general law, we as a service provider are responsible according to Art. 7 Paragraph 1 of the Telemedia Act (TMG) for our own contents on these pages. According to Arts. 8 to 10 TMG we are not obliged as a service provider to monitor transmitted or stored third party 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 possible from the date of knowledge of a specific 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 such content. The respective provider or operator of the pages is always responsible for the contents of any linked site. The linked sites were checked at the time of linking for possible violations of law. Illegal contents were not recognised 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 remove such links immediately.

The contents and material on these pages created by the site operator are subject to German Copyright Law. Duplication, processing, distribution and any kind of exploitation outside the limits of copyright require the written consent of the respective author or creator. Downloads and copies of these pages are only permitted for private, non-commercial use. As far as the content is not created by the website operator, the copyrights of third parties shall be respected. Content from third parties is marked as such. Should anyone nonetheless become aware of copyright infringement, we ask to be notified accordingly. Upon notification of violations, we will remove such content immediately.
