As a service provider, we are responsible for our own content on these pages under the general laws according to § 7 para.1 TMG. According to §§ 8 to 10 TMG, however, we are not obligated as a service provider to monitor transmitted or stored third-party information or to investigate circumstances that indicate illegal activity.

Upon becoming aware of such infringements, we will remove such content immediately.

The respective provider or operator of the sites is always responsible for the content of the linked sites. The linked pages were checked for possible legal violations at the time of linking. Illegal contents were not recognizable at the time of linking.
However, a permanent control of the contents of the linked pages is not reasonable without concrete evidence of a violation of the law. If we become aware of any infringements, we will remove such links immediately.
