Liability for content

Content for the online offering: The author accepts no liability for the currentness, correctness, completeness or quality of the information provided. Liability claims against the author for damages of a material or non-material nature resulting from the use or non-use of the information provided or respectively resulting from use of incorrect or incomplete information are excluded as a matter of principle, insofar as it cannot be proven that the author has been wilfully or grossly negligent. All offerings are non-binding and subject to confirmation. The author reserves the express right to amend, supplement or delete parts of the website or the entire offering or to temporarily or permanently cease publication without prior notice.

Liability for links

References and links: Should direct or indirect references be made to third-party websites (“links”) that lie outside the author’s scope of responsibility, then any liability obligation will only come into force in the event the author is aware of the content and has the technical capacity and can reasonably be expected to prevent use should this content be unlawful. The author herewith expressly declares that no illegal content could be identified on the linked sites at the time of linking. The author has no influence whatsoever on the current and future design, content or copyright of the linked/connected sites. They therefore herewith expressly distance themselves from all content on the linked/connected sites that was amended subsequent to linking. This statement applies to all links and references made within the scope of the author’s own Internet offering as well as to third-party entries made in guest books, discussion forums and mailing lists created by the author. The provider of the site that was referred to will be solely responsible for illegal, incorrect or incomplete content and, in particular, for damages resulting from the use or non-use of such information provided. Persons who merely refer to the relevant publication via a link will not bear any liability.


Copyright and trademark rights: The author makes every effort to comply with copyright for the graphics, audio files, video sequences and texts used in all their publications; to use graphics, audio files, video sequences and texts which they compiled themselves or to make use of licence-free graphics, audio files, video sequences and texts. All trademarks and brand names that are mentioned and, where applicable, have been registered by third parties, are subject to the provisions of the relevant valid trademark law and the ownership rights of the relevant registered owners without limitation. A mere mention of a trademark or brand name will not provide grounds for the conclusion that they are not protected under third-party rights. The copyright for published material created by the author remains the sole property of the author of the pages. Reproduction or use of such graphics, audio files, video sequences and texts in other electronic or printed publications will require the author’s express consent.

Data protection and privacy

Insofar as the Internet offering includes the option to provide personal or business data ((email addresses, names, addresses), then the disclosure of this data by the user will take place on a solely voluntary basis. The use of, and payment for, all services offered will, insofar as technically possible and can reasonably be expected, also be permitted without provision of such data or by providing anonymized data or a pseudonym. For details, please read our privacy policy.

Legal validity

Insofar as parts or specific formulations of this text do not, no longer or only incompletely comply with current legislation, then the content and validity of the remaining parts of this document will remain unaffected by this.
