Liability for content

The contents of our pages were created with great care. However, we can not assume any liability for the accuracy, completeness and timeliness of the content. As a service provider we are responsible according to § 7 Abs.1 TMG for  own contents on these sides according to the general laws. According to §§ 8 to 10 TMG, however, we as a service provider are not obliged to monitor transmitted or stored third-party information or to investigate circumstances that indicate an illegal activity. Obligations to remove or block the use of information under general law remain unaffected. A liability in this regard, however, is only possible from the date of knowledge of a specific infringement. Upon notification of appropriate violations, we will remove this content immediately.

Liability for links

Our offer contains links to external websites of third parties on whose contents we have no influence. Therefore, we can not assume any liability for these external contents. The respective provider or operator of the pages is always responsible for the contents of the linked pages. The linked pages were checked for possible legal violations at the time of linking. Illegal content was not recognizable at the time of linking. However, a permanent content control of the linked pages is not reasonable without concrete evidence of an infringement. Upon notification of violations, we will remove such links immediately.
