Dispute resolution
The European Commission discontinued its online dispute resolution platform on 20 July 2025, so no link to it is provided here.
We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration body.
Liability for content
As a service provider we are responsible for our own content on these pages under general law (section 7 (1) DDG). Under sections 8 to 10 DDG, however, we are not obliged to monitor transmitted or stored third-party information or to investigate circumstances that indicate unlawful 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 at which a concrete infringement becomes known. If we become aware of such infringements, we will remove the content immediately.
Liability for links
Our site contains links to external third-party websites over whose content we have no influence. We therefore cannot accept any liability for that 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; no unlawful content was apparent. Permanent monitoring of the linked pages is not reasonable without concrete evidence of an infringement. If we become aware of legal violations, we will remove such links immediately.
Copyright

Reproduction, editing, distribution and any kind of use beyond the limits of copyright require the written consent of the respective author or creator. Downloads and copies of this page are permitted for private, non-commercial use only.
Where content on this page was not created by the operator, the copyrights of third parties are respected and such content is identified as such. Should you nevertheless become aware of a copyright infringement, please let us know. If we become aware of legal violations, we will remove such content immediately.
