Liability for content

As a service provider, we are responsible for our own content on these pages based on § 7 para.1 TMG (German Telemedia Act) according to general laws. Based on §§ 8 to 10 TMG (German Telemedia Act), as a service provider we are not obliged to monitor or, depending on circumstances, research transmitted or saved external information, which points to illegal activity.

Obligations to remove or block the use of information according to the general laws remain unaffected by this. However, liability in this respect is only possible from the time of recognising a specific breach of the law. When becoming aware of relevant breaches of law, we will remove this content immediately.

Liability for links

Our services include links to external websites of third parties and we do not have any influence over their content. We cannot therefore assume any guarantee for this external content. The provider or operator in question is always responsible for the content of the linked pages. The linked pages have been checked at the time of linking for possible breaches of the law. No illegal content was found at the time of linking.

However, ongoing checking of the content of linked pages is not possible without specific indications of a breach of the law. When becoming aware of breaches of law, we will remove such links immediately.

Copyright law

The content and writing on these pages created by the site operator are subject to German copyright law. The reproduction, processing, distribution and any type of use outside the boundaries of copyright law require the written agreement of the relevant authors or writers. Downloads and copies of this page are only intended for private, non-commercial use.

Insofar as the content of this site has not been drafted by the operator, the copyright of third parties is respected. The content of third parties in particular will be marked as such. Nevertheless, should you become aware of a breach of copyright, we would ask you to let us know accordingly. When being appraised of breaches of law, we will remove such content immediately.
