Liability for content

As a service provider we are responsible for our own content on these pages under the general laws, pursuant to section 7 (1) DDG. Pursuant to sections 8 to 10 DDG, however, we are not obliged as a service provider to monitor transmitted or stored third-party information or to investigate circumstances that indicate unlawful activity.

Obligations to remove or block the use of information under the general laws remain unaffected by this. Liability in this respect is, however, only possible from the point in time at which we become aware of a specific infringement. If we become aware of such infringements, we will remove the content concerned immediately.

Liability for links

Our offering contains links to external third-party websites over whose content we have no influence. For that reason we cannot accept any responsibility for that third-party content. The respective provider or operator of the linked pages is always responsible for their content. The linked pages were checked for possible legal infringements at the time of linking. No unlawful content was identifiable at the time of linking.

Permanent monitoring of the content of the linked pages is, however, not reasonable without concrete indications of an infringement. If we become aware of infringements, we will remove such links immediately.

Copyright

The content and works created by the site operators on these pages are subject to German copyright law. Reproduction, editing, 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 permitted for private, non-commercial use only.

Where the content on this page was not created by the operator, the copyright of third parties is respected. In particular, third-party content is marked as such. Should you nevertheless become aware of a copyright infringement, we ask you to inform us accordingly. If we become aware of infringements, we will remove such content immediately.
