Content of Website

The author provides no guarantee of the currency, accuracy, completeness or quality of the information provided. Liability claims against the author that are based on damages of a material or immaterial nature that were caused by the use or failure to use the information provided or through the use of inaccurate and incomplete information are strictly excluded, to the extent that no intentional or grossly negligent culpability on the part of the author can be demonstrated.

All offers are subject to change and non-binding. The author reserves the right to change, amend or delete parts of the pages or the entire site without prior notice or to temporarily suspend or permanently terminate its publication.

References and Links

In the case of direct or indirect references to external websites ("Links"), which lie outside the author’s scope of responsibility, there would only be a liability obligation in effect in the event that the author was aware of the contents and it was technically possible and reasonable for it to prevent the use of illegal content in that case.

The author therefore declares expressly that at the time when the links were set, the correspondingly linked pages were free of illegal contents. The author has no influence whatsoever on the current and future design and contents of the sites/pages to which links have been set. For that reason it herewith distances itself expressly from all contents to linked pages/sites that were modified after the links were set. This statement applies to all links and references set within its own website as well as for external entries in guest books, discussion forums and mailing lists set up by the author. The provider of the page to which the link or reference leads is solely responsible for illegal, inaccurate or incomplete contents and especially for damages that arise from the use or non-use of such information, and not the party who only refers to them using links on the publication in question.

Copyrights and Trademark Rights

The author strives in all publications to respect the copyrights to the graphics, audio documents, video sequences and texts used; to use self-generated graphics, audio documents, video sequences and texts or to make use of graphics, audio documents, video sequences and texts that are in the public domain.

All trademarks and brands mentioned on the website and possibly protected by third parties are subject without restriction to the provisions of the specifically applicable trademark laws and the ownership rights of the respective registered owner. The mere fact that the name is mentioned does not lead to the inference that the trademark is not protected by the rights of third parties!

The copyright on published objects that the author itself created remains solely with the page author. Reproduction or use of such graphics, audio documents, video sequences and texts in other electronic or printed publications without the expressed consent of the author is prohibited.

Legal Enforceability of this Liability Exclusion

This liability exclusion is to be deemed a part of the website from which reference is made to this page. To the extent that parts or individual formulations of this text do not conform to the current state of the law, no longer conform to it or do not fully conform to it, the remaining parts of the document are not affected by this condition in either their content or their enforceability.
