Information on online dispute resolution pursuant to Article 14 (1) of the ODR Regulation and § 36 of the German Consumer Dispute Resolution Act (VSBG). The European Commission provides a platform for online resolution of disputes in consumer law (ODR platform) that result from online purchase contracts and online service contracts. This platform can be found on the Internet at the following URL:

We are not obligated and generally also unwilling to participate in any dispute resolution proceedings before a consumer arbitration body.

Liability for content
Pursuant to § 7 (1) of the German Telemedia Act (TMG), as a service provider we are responsible under general law for our own contents on this website. Pursuant to §§ 8 to 10 of the German Telemedia Act (TMG), however, as a service provider we are not obligated to monitor transferred or stored information of third parties or to research circumstances that suggest an illegal activity.

Obligations to remove or block the use of information as per general law remain unaffected by this. Any liability in this respect is, however, only incurred from the moment that knowledge of the specific breach of law is obtained. These contents will be immediately removed upon discovery of any corresponding infringements.

Liability for links
Our offer contains links to external web pages of third parties, whose contents are not subject to our influence. We can therefore also not assume liability for these external contents. The respective provider or operator of the websites is always responsible for the content of linked pages. The linked pages were checked for potential legal infringements at the time the link was established. No unlawful content could be determined at the time the link was established.

However, we cannot reasonably be expected to exercise permanent control over the content of the linked sites without any specific indications of legal infringements. We will remove the respective contents promptly on becoming aware of any infringements.

German copyright law governs the content and works created by the page operators and presented on these pages. Copying, processing, distributing and any kind of use outside the limits of copyright law require the written approval of the respective author/creator. The download files we provide, including downloads and copies of this site, are intended solely for private and non-commercial use.

Insofar as the contents of this page were not compiled by the operator, the copyrights of third parties are respected. In particular, the content of third parties is marked as such. Should you still have reason to believe that a copyright violation has occurred despite the precautionary measures taken, we request immediate notification. We will remove the respective contents promptly on becoming aware of any infringements.
