1. Content of the online offer

The author is unable to guarantee the topicality, correctness, completeness or quality of the information provided. Any liability claims against the author which refer to material or intellectual damages that have been caused by using or not using the information provided, or by using faulty or incomplete information, are generally excluded, unless the author has acted intentionally or grossly negligently. All offers are subject to change and non-binding. The author explicitly reserves the right to alter, complete or delete parts of the sites or the entire website without any further notice, or to temporary or finally stop its publication.

2. References and links

With regard to direct or indirect references to external websites ("hyperlinks") that are beyond the author’s realm of responsibility, an obligation to accept liability would only come into effect if the author has knowledge of the contents and can be reasonably expected, having the technical possibilities, to prevent use of said websites in case of illegal contents. Herewith the author explicitly declares that at the moment of setting the links no illegal contents whatsoever could be recognized on the websites to be linked. The author has no influence whatsoever on the current or future design, contents or authorship of the linked sites. Therefore he explicitly distances himself from any contents of any linked sites that have been altered after setting the link. This declaration is true for any link and reference set within his own internet offer as well as for third party entries in guest books, discussion forums and mailing lists implemented by the author. For any illegal, faulty or incomplete contents, and in particular for any damages resulting from the use or non-use of information presented in such a way, only the provider of the site referred to shall be held solely responsible, not the one who merely refers to the relevant publications via links.

3. Copyright and labelling law

Every effort has been made by the author to acknowledge in all publications the copyright for the diagrams, sound files, video sequences and texts used, and to use diagrams, sound files, video sequences and texts made by the author himself or to fall back on diagrams, sound files, video sequences and texts that require no licence. All trademarks mentioned within the website contents that may be protected by third parties are exclusively subject to the regulations of the prevailing labelling law and property rights of any registered proprietor. The mere fact that a trademark is mentioned does not mean that it is not protected by third-party rights! All rights reserved for published objects made by the author himself. Reproduction or use of such diagrams, sound files, video sequences and texts in other electronic or printed publications shall not be permitted without the prior permission of the author.

4. Data protection

Insofar as there is the possibility within the website offer to enter personal or business-related data (e-mail addresses, names, postal addresses), the user explicitly acknowledges that these data are divulged voluntarily. The use of and payment for all services offered – as far as technically possible and reasonable – is also permitted without entering such data or by entering anonymized data or a pseudonym. The use by third parties of the contact data published in the imprint or similar contexts, such as postal addresses, phone and fax numbers or e-mail addresses to send information that has not been explicitly requested is not permitted. We explicitly reserve the right to initiate judicial proceedings against the senders of so-called spam mails in case of any infringement.
