This commercial site is maintained by:

1. Website content
The author accepts no liability whatsoever for the information provided being up to date, correct or complete, or for the quality of the information. All liability claims against the author relating to material or immaterial damage and caused by the use or non-use of the information provided and/or the use of incorrect and incomplete information are excluded, insofar as no intent or gross negligence on the part of the author can be demonstrated. All prices quoted are subject to change and non-binding. The author expressly reserves the right to change, supplement or delete the website, in whole or in part, or to suspend or cease publication.

2. References and links
In the case of direct or indirect hyperlinks that direct the user to third-party websites that lie outside the scope of the author’s responsibility, the author would only be liable insofar as he was aware of the content of the third-party site and insofar as it would be technically possible and reasonable for him to prevent the site being used in the event of it containing illegal content. The author hereby expressly declares that, at the time the links were created, no illegal content was identifiable on the sites being linked to. The author has no influence whatsoever on the current and future design, content or authorship of the sites being linked/connected to. For this reason, the author hereby expressly distances himself from all content on linked/connected sites that has been changed since the links were created. This applies to links and references created on the author’s own Internet site, to third-party entries made in guest books established by the author, discussion forums, link directories, mailing lists and all other kinds of database to whose content third parties could possibly have write access. The provider of the site being linked to, and not the person who merely refers users to the site by providing links, bears sole liability for illegal, incorrect or incomplete content and, in particular, for damage arising from the use or non-use of information provided in this way.

3. Copyright and trademark law
The author seeks, in all publications, to respect the copyrights of the images, graphics, sound files, video sequences and texts used; to use images, graphics, sound files, video sequences and texts that he himself has created; or to make use of images, graphics, sound files, video sequences and texts that do not require a licence. All trademarks named on these web pages may have been protected by third parties and are subject without restriction to the provisions of applicable trademark law and the ownership rights of their respective registered owners. By the mere fact of their having been named, it is not to be assumed that trademarks are not protected by third-party rights. The copyright for published content that has been created by the author of these pages lies exclusively with the author. The reproduction or use of such graphics, sound files, video sequences and texts in other electronic or printed publications is not permitted without the express consent of the author.

4. Data protection
If these pages contain any means for entering personal or company data (email addresses, names, postal addresses), then users disclose this information on a purely voluntary basis. Insofar as it is technically possible and reasonable, all services offered may be used and paid for without providing such data or by providing anonymised data or a pseudonym. Contact details such as postal addresses, telephone and fax numbers and email addresses published in the legal notice or other comparable part of the website may not be used to send information that has not been expressly solicited. The website author expressly reserves the right to take legal action against senders of so-called spam emails in the event of this provision being breached.
