Content of the online offer
The author gives no guarantee for the currency, accuracy, completeness or quality of the information provided. Liability claims against the author on the grounds of material or immaterial damages caused by the use or non-use of the information offered or the use of incorrect or incomplete information, are fundamentally excluded, unless the author can demonstrably be shown to have acted with deliberate or gross negligence.
All offers are made without commitment, and are non-binding. The author expressly reserves the right to change, extend or delete part or all of the offer without prior notice, or to temporarily or permanently discontinue publication.

References and links
In the event of direct or indirect references to other Internet sites (“links”), which lie outside the area of responsibility of the author, any liability obligation would only come into effect if the author is aware of the contents, and it would be technically possible and reasonable for him to prevent the use in the event of illegal contents.
The author hereby expressly declares that the linked sites did not contain any illegal contents at the time of creating the links. The author has no influence over the current or future design, the contents or the copyright of the linked/connected sites. He hereby expressly dissociates himself from all contents of all linked/connected sites that are changed after the creation of the links. This applies to all links and references created within the author’s own Internet offer, and to all outside entries in guest books, discussion forums and mailing lists set up by the author. The provider of the site to which reference is made is solely liable for illegal, incorrect or incomplete contents, and particularly for damages arising from the use or non-use of such information, and not the person who simply makes reference to the relevant publication by means of links.

Copyright and trademark law
The author has made every effort to observe the copyright of the graphics, audio sequences, video sequences and texts in all publications, to use his own graphics, audio sequences, video sequences and texts, or to use only graphics, audio sequences, video sequences and texts not subject to licensing.
All brands and trademarks used within the Internet site, including those registered by third parties, are subject without restriction to the stipulations of the applicable trademark law and the proprietary rights of the relevant registered owners. The mere reference to such brands or trademarks does not give grounds for the assumption that trademarks are not protected by the proprietary rights of third parties!
The copyright for published objects created by the author himself remains solely with the author of the site. The copying or use of such graphics, audio sequences, video sequences and texts in other electronic or printed publications requires the express consent of the author.

Data protection
Where the possibility exists within the Internet offer for the entry of personal or business data (e-mail addresses, names, addresses), the disclosure of this data on the part of the user is made on an expressly voluntary basis. The use and payment of all such services offered   as far as technically possible and reasonable   is also allowed without the provision of such data, or by the entry of anonymised date or a pseudonym.

Legal applicability of this disclaimer
This liability disclaimer should be regarded as part of the Internet offer from which reference was made to this page. In the event that any parts of it or individual wording of the text does not, does not any longer or does not completely conform to the prevailing legal requirements, this shall not affect the content or validity of the remaining parts of the document.
