Content of the online offerings
The author assumes no responsibility for the timeliness, correctness, completeness or quality of the information that is provided. Liability claims against the author with regard to tangible or intangible damages resulting from the use or nonuse of the information offered or from the use of erroneous and incomplete information are fundamentally excluded, provided that there is no proof of deliberate or grossly negligent culpability on the part of the author.
The author expressly reserves the right to alter parts of pages or the entire range of offerings, supplement or delete content, or cease publication temporarily or permanently, without separate announcement.
References and links
A liability obligation for direct or indirect references to external websites (hyperlinks) that are outside the author’s area of responsibility would come into force only if the author has direct knowledge of the content of the websites and if it would be technically possible and reasonable for him to prevent the use of this content if it is contrary to law.
The author hereby expressly declares that at the point in time when the links were created no illegal content could be discerned on the pages to be linked. The author has no influence whatsoever on the current and future design, content or authorship of the linked/connected pages. Consequently, he expressly distances himself from the entire content of all the linked/connected pages that was altered after the point in time when the links were created. This statement applies to all of the links and references provided on his own website, as well as to third-party entries in the guest books, discussion forums, link directories, mailing lists, and all other forms of databases set up by the author, in which external parties can make written alterations of the content. The provider of the website to which users are directed is solely responsible for illegal, erroneous or incomplete content, and especially for damages arising from the use or nonuse of information that is offered in this way. The author, who merely directs users to the publication in question via links, bears no responsibility in such cases.
Copyright and trademark rights
The author strives to respect the copyright of the images, graphics, audio documents, video clips, and texts used in all of his publications; to use self-created images, graphics, audio documents, video clips, and texts; or to rely on license-free graphics, audio documents, video clips, and texts.
All of the brand names and trademarks that appear on the website and that may be protected by third parties are subject without restriction to the terms of the relevant trademark law and the right of ownership of the respective registered owner. The sole fact that such trademarks are cited shall not be deemed to indicate that they are not protected by third-party rights.
The copyright for published material created by the author remains the property of the author of the pages. The duplication or use of such graphics, audio documents, video clips, and texts in other electronic or printed publications is not permitted without the express consent of the author.
