Liability for content

As a service provider, we are responsible for our own content on these pages in accordance with the general laws, as defined in § 7, para. 1 Telemedia Act (“TMG”). According to §§ 8 to 10 TMG, we as a service provider are not obliged, however, to monitor transferred or stored external information, or to research circumstances which may indicate illegal activity.

Obligations to remove or block the use of information according to the general laws remain unaffected. Liability in this regard is however only possible from the point in time at which knowledge of a specific legal infringement was gained. On becoming aware of any such legal infringements, we shall remove this content immediately.

All data and information provided on was made available according to our best knowledge and belief. Even if we are consistently at pains to keep all information up to date, errors and ambiguities may still arise. We can therefore not provide any guarantee for the accuracy, currency and completeness of our texts. No liability is assumed for damage caused directly or indirectly by the use of the information.


Liability for links

Our offer contains links to external websites of third parties, over whose content we have no influence. For this reason, we also cannot assume any guarantee for this external content. In all cases, the respective provider or operator of the pages is responsible for the content of the linked pages. The linked pages were checked for potential legal infringements at the time of linking. At the time of linking, no illegal content could be identified.

However, without specific indicators of legal infringement, permanent monitoring of the content of the linked pages cannot reasonably be expected. On becoming aware of legal infringements, we shall remove such links immediately.



The content and work on these pages that are produced by the page operators are subject to German copyright. The reproduction, processing, dissemination and any type of use beyond the limits of copyright require the written authorisation of the respective author or creator. Downloads and copies of this website are permitted for private, non-commercial use. Should the content on this website not have been created by the operator, the copyright of third parties shall be respected. In particular, the content of third parties shall be labelled as such. Should you nevertheless become aware of a copyright infringement, we request that you inform us accordingly. On becoming aware of legal infringements, we shall remove such content immediately.
