Liability for content
As a service provider we are responsible for our own content on these pages in accordance with general law. However, we are not obliged to monitor transmitted or stored third-party information, or to investigate circumstances that indicate illegal activity. Obligations to remove or block the use of information under general law remain unaffected. Liability in this respect is only possible from the point in time at which a concrete infringement of the law becomes known. If we become aware of any such infringements, we will remove the content in question immediately.
Liability for links
Our website 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; illegal content was not recognisable at that time. However, permanent monitoring of the content of linked pages is not reasonable without concrete evidence of an infringement. If we become aware of any legal 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. Duplication, processing, distribution and any form of commercialisation beyond the scope of copyright law require the written consent of the respective author or creator. Downloads and copies of this site are only permitted for private, non-commercial use.
Insofar as the content on this site was not created by the operator, the copyrights of third parties are respected and third-party content is marked as such. Should you nevertheless become aware of a copyright infringement, please inform us accordingly. If we become aware of any infringements, we will remove such content immediately.
