The contents of our pages were created with the utmost care. However, we cannot assume liability for the correctness, completeness and up-to-dateness of the contents. Pursuant to § 7, Sect. 1 TMG (German Teleservices Act), as the service provider, we are liable for our own contents on these pages according to general legislation. Nevertheless, pursuant to §§ 8 to 10 TMG we, as the service provider, are not obliged to check the transmitted information or the stored foreign information, nor to investigate the circumstances that indicate illegal activities. Any obligation to remove or stop the use of information will remain unaffected pursuant to general legislation. Any liability resulting thereof will not be possible until knowledge of a specific infringement has been gained. Upon knowledge of any such infringements, we will remove these contents immediately.

Liability for Links

Our offer contains links to the external webpages of third parties on the contents of which we do not exert any influence. Therefore we cannot assume liability for these foreign contents. At any time, the respective provider or operator is liable for the contents of those linked pages. Linked pages were checked for any possible infringements at the moment of linking. No unlawful contents were identified at the moment of linking. A permanent textual control of the linked pages without any concrete clues on an infringement is not reasonable. Upon gaining knowledge of any such infringements, we will remove these links immediately.
