Liability for content
As a service provider we are responsible for our own content on these pages under the general laws in accordance with § 7 (1) DDG. Under §§ 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. Liability in this respect is, however, only possible from the point in time at which we become aware of a specific infringement. Upon becoming aware of such infringements, we will remove the content in question without delay.
Liability for links
Our offering contains links to external third-party websites over whose content we have no influence. We therefore cannot accept any liability for this 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 violations at the time of linking; unlawful content was not identifiable at that time. Permanent monitoring of the content of the linked pages is, however, not reasonable without concrete indications of a legal violation. Upon becoming aware of legal violations, we will remove such links without delay.

The content and works created by the site operator on these pages are subject to German copyright law. Reproduction, adaptation, 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. Insofar as the content on this page was not created by the operator, the copyrights of third parties are respected. Should you nevertheless become aware of a copyright infringement, please notify us accordingly. Upon becoming aware of legal violations, we will remove such content without delay.
