The European Commission provides a platform for online dispute resolution (ODR): https://ec.europa.eu/consumers/odr.
You can find my email address above in this legal notice.

I am not willing or obliged to participate in dispute resolution proceedings before a consumer arbitration board.

As a service provider, I am responsible for my own content on these pages under general laws according to § 7(1) TMG (German Telemedia Act). According to §§ 8 to 10 TMG, however, I am not obligated as a service provider to monitor transmitted or stored external information or to investigate circumstances indicating illegal activity.

Obligations to remove or block the use of information under the general laws remain unaffected. However, liability in this respect is only possible from the time of knowledge of a specific infringement. If I become aware of any such legal violations, I will remove this content immediately.

My website contains links to external third-party websites, over whose content I have no control. Therefore, I cannot accept any responsibility for these external contents. The respective provider or operator of the sites is always responsible for the content of the linked sites. The linked sites were checked for possible legal violations at the time of linking. Illegal contents were not identifiable at the time of linking.

Permanent content control of the linked pages is not reasonable without concrete evidence of an infringement. If I become aware of any legal violations, I will remove such links immediately.

The contents and works created by the site operators on these pages are subject to German copyright law. The duplication, editing, distribution, and any kind of exploitation outside the limits of copyright law require the written consent of the respective author or creator. Downloads and copies of this page are only permitted for private, non-commercial use.

As far as the contents on this site were not created by the operator, the copyrights of third parties are respected. In particular, third-party content is marked 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.
