1. Content of online offering
The author provides no guarantee for the up-to-dateness, accuracy, completeness or quality of the information provided. Any liability claims brought against the author in respect of material or non-material losses caused by the use or non-use of the offered information or by the use of false and/or incomplete information shall therefore be precluded insofar as there is no proof of wilful intent or gross negligence on the part of the author. All offers are non-binding and subject to confirmation. The author explicitly reserves the right to modify, add to or delete sections of the pages or the entire offering without separate notice, or to withdraw the publication either temporarily or permanently.

2. References and links
In the case of direct or indirect referrals to third-party websites (‘hyperlinks’) which lie outside the author’s area of responsibility, liability shall exclusively arise in the event that the author is aware of the associated comment and it would be technically feasible and reasonable for the author to prevent the use of said third-party web pages in the event of their content being illegal. The author hereby expressly declares that no illegal content was evident on the pages to be linked at the time the link was created. The author has no influence whatsoever on the current or future design, content or authorship of the linked or referenced pages. For this reason, the author hereby expressly dissociates himself from the entire content of any linked or referenced pages changed after the creation of the relevant links. This statement applies to all links and references posted on the author's own internet offering as well as for third-party entries in visitors' books, discussion forums and mailing lists provided by the author. Liability for illegal, erroneous or incomplete content and, in particular, for losses resulting from the use or non-use of such offered information shall be borne exclusively by the provider of the page referred to and not by the party referring to the respective publication by means of links.

3. Copyright and trademark laws
The author makes every effort in all publications to observe the copyrights of the graphics, sound files, video sequences and texts used, to use self-produced graphics, sound files, video sequences and texts, or to draw on licence-free graphics, sound files, video sequences and texts. All brand and trademarks mentioned in the internet offering and possibly protected by third-parties shall be unrestrictedly subject to the provisions of the respective, current trademark law and to the proprietary rights of the respective registered owners. The mere mention shall not be construed as meaning that trademarks are not protected by the rights of third-parties. The copyright for published objects created by the author shall remain solely with the author of the pages. The reproduction or use of such graphics, sound files, video sequences and texts in other electronic or printed publications shall, in the absence of the express agreement of the author, be prohibited.

4. Data protection
Insofar as the internet offering provides for the entry of personal or business data (e-mail addresses, names, addresses), disclosure of this data by the user shall be on an explicitly voluntary basis. Insofar as this is technically feasible and reasonable, the use of and payment for all offered services shall also be permissible without entry of such data or through entry of anonymised data or a pseudonym. It is not permissible for contact data posted in the editorial information or similar information, e.g. postal addresses, telephone and fax numbers, e-mail addresses, to be used by third-parties for sending information not explicitly requested. We expressly reserve the right to take legal action against senders of so-called ‘spam e-mails’ in case of infringement of the above provision.

5. Legal effectiveness of this disclaimer
This disclaimer shall be deemed to constitute part of the internet offering containing a link to this page. Insofar as parts or individual wordings of this text fail to, no longer or incompletely conform to the current legal framework, this shall not affect the content and validity of the remaining parts of the document.
