Disclaimer of liability (Disclaimer)

Liability for content

As a service provider, we are responsible for our own content on these pages according to the general German laws according to § 7 Abs.1 TMG. According to §§ 8 to 10 TMG, however, we as service providers are not obliged to monitor transmitted or stored third-party information or to investigate circumstances which indicate an illegal activity. Obligations to remove or block the use of information according to general laws remain unaffected. Liability in this respect, however, is only possible from the time of knowledge of a concrete infringement. If we become aware of any such infringements, we will immediately remove such content.

Liability for links

Our offer contains links to external websites of third parties on whose content we have no influence. Therefore, we cannot assume any liability for these third-party contents. The respective provider or operator of the pages is always responsible for the content of the linked pages. The linked pages were checked for possible legal violations at the time of linking. Illegal contents were not recognizable at the time of linking. However, a permanent control of the content of the linked pages is not reasonable without concrete indications of an infringement. If we become aware of legal violations, we will immediately remove such links.


The content and works created by the site operators on these pages are subject to German copyright law. The copying, 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 this page are only permitted for private, non-commercial use. Insofar as the operator has not created the content on this site, the copyrights of third parties are respected. In particular contents of third parties are marked as such. If you are nevertheless aware of a copyright infringement, we ask for a corresponding note. If we become aware of legal violations, we will immediately remove such content.
