Liability for contents

Under § 7 par. 1 TMG (Telemediengesetz; German Telemedia Act), we, as a service provider, are responsible for our own content on these pages in accordance with general legislation. However, according to §§ 8 to 10 TMG we are not obliged as service provider to monitor third-party information transmitted or stored or to investigate circumstances indicating unlawful activity.
