Despite careful control of the content, we assume no liability for the content of external links. The operators of the linked pages are solely responsible for their content.

1. content of the online offer
The authors do not assume any liability for the topicality, correctness, completeness or quality of the information provided. Liability claims against the authors relating to material or non-material damage caused by the use or non-use of the information provided or by the use of incorrect or incomplete information are excluded, unless it can be proven that the authors acted with intent or gross negligence. All offers are subject to change and non-binding. The author expressly reserves the right to change, supplement, delete or temporarily or permanently cease publication of parts of the pages or the entire website without prior notice.

2. references and links
The author is not responsible for any contents linked or referred to from his pages – unless he has full knowledge of illegal contents and would be able to prevent the visitors of his site fromviewing those pages. The author hereby expressly declares that at the time the links were created, no illegal content was identifiable on the linked pages. The author has no influence on the current and future design, content or authorship of the linked pages. Therefore, he hereby expressly dissociates himself from all contents of all linked pages that were changed after the link was set. This statement applies to all links and references set within the own Internet offer as well as to external entries in discussion forums, link directories, provider lists set up by the author and in all other forms of databases to whose content external write access is possible. For illegal, incorrect or incomplete contents and especially for damages resulting from the use or non-use of such information, only the provider of the linked page is liable, not the one who has linked to the respective publication.

The authors endeavor to observe the copyrights of the graphics, sound documents, video sequences and texts used in all publications, to use graphics, sound documents, video sequences and texts created by themselves or to use license-free graphics, sound documents, video sequences and texts. All brands and trademarks mentioned within the Internet offer and possibly protected by third parties are subject without limitation to the provisions of the applicable trademark law and the ownership rights of the copyright owner.

The copyright for published objects created by the author himself remains solely with the author of the pages. Any duplication or use of objects such as diagrams, sounds or texts in other electronic or printed publications is not permitted without the author’s agreement.
