Christian Schappeit, address as above.
Consumer dispute resolution
Our offers are directed exclusively at entrepreneurs (Unternehmer) within the meaning of § 14 BGB. We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.
Liability for content
As a service provider, we are responsible for our own content on these pages in accordance with general law pursuant to § 7(1) DDG. However, pursuant to §§ 8 to 10 DDG, we as a service provider 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, however, only possible from the time at which a specific infringement becomes known. Upon becoming aware of such infringements, we will remove the content concerned without delay.
Liability for links
Our website contains links to external third-party websites over whose content we have no influence. We therefore cannot accept any liability for this 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 infringements at the time of linking; no unlawful content was recognisable at that time. Permanent monitoring of the content of the linked pages is not reasonable without concrete indications of an infringement. Upon becoming aware of infringements, we will remove such links without delay.
Copyright
The content, texts and images created by the site operator (including the CMP42 key visuals) are subject to German copyright law. Reproduction, adaptation, distribution and any form of exploitation beyond the limits of copyright law require the written consent of the rights holder. Insofar as content on this site was not created by the operator, the copyrights of third parties are respected and marked as such. Should you nevertheless become aware of a copyright infringement, please notify us.
Applicable law
The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
