Liability for Content
As a service provider, we are responsible for our own content on these pages in accordance with § 7 Abs.1 TMG (German Telemedia Act) and general laws. 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.
Obligations to remove or block the use of information under general law remain unaffected. However, liability in this regard is only possible from the point in time at which we become aware of a specific legal violation. Upon becoming aware of such violations, we will remove this content immediately.
Liability for Links
Our app may contain links to external websites of third parties over whose content we have no influence. Therefore, we cannot assume any liability for this external content. The respective provider or operator of the pages is always responsible for the content 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, permanent monitoring of the content of the linked pages is not reasonable without concrete evidence of a violation of the law. Upon becoming aware of legal violations, we will remove such links immediately.

Duplication, processing, distribution, and any kind of exploitation outside the limits of copyright law require the written consent of the respective author or creator.

Insofar as the content on this app was not created by the operator, the copyrights of third parties are respected. In particular, third-party content is marked as such.
