1. Content of the online offer

The author does not assume any liability whatsoever for the current accuracy, correctness, completeness or quality of the information provided. Liability claims against the author based on damage of a material or non-material nature resulting from the use of or failure to use the presented information and / or the use of incorrect and incomplete information are categorically excluded, provided that the author is not guilty of demonstrably wilful or gross negligence.
All offers are subject to change and non-binding. The author expressly reserves the right to change, supplement, or delete parts of the pages or the entire content without separate notice and to discontinue publication thereof either temporarily or permanently.

2. References and links

As regards, direct or indirect references to external websites (“hyperlinks”), which are outside the area of responsibility of the author, liability would only be assumed if the author had knowledge of the contents and if it was technically possible and feasible to prevent their use in case of illegal content.
The author hereby expressly declares that no illegal content was found on the linked pages at the time the links were made. The author has no influence whatsoever on the current and future design, contents and authorship of the linked/referenced pages. For this reason, the author expressly dissociates himself from the contents of all linked / referenced pages which were changed after the links were first established. This statement applies to all links and references set up within the author’s own internet presence as well as to external entries in guest books, discussion forums, link directories and mailing lists created by the author, and in all other forms of databases whose content is subject to external write access. Only the provider of the page to which reference was made shall be liable for illegal, incorrect or incomplete contents and notably for damage resulting from the use of or failure to use such information provided, and not the person who merely refers to the publication in question via links.

3. Copyright and trademark law

The author strives in all publications to use his own images, graphics, sound files, video sequences and texts and to respect the copyrights of the images, graphics, sound files, video sequences and texts or to fall back on license-free graphics sound documents, video sequences and texts.
All brands and trademarks mentioned within the Internet offer and possibly protected brands and trademarks are subject to the provisions of applicable trademark law and the ownership rights of the copyright owner.

The copyright for publications created by the author himself remains solely with the author. Any reproduction or use of such graphics, sound files, video sequences and texts in other electronic or printed publications without the express permission of the author, is not permitted.

4. Privacy

Provided that the possibility of entering personal or business details (email addresses, names, and addresses) exists within the Internet offer, the disclosure of such data on the part of the user is done on an expressly voluntary basis. Using and paying for all services offered is – in as much as this is technically possible and feasible – also permitted without entering such data and / or anonymously entering data or by using an alias. The use of details within the framework of the imprint or similar published details, such as postal addresses, telephone and fax numbers and e-mail addresses by third parties for the purpose of sending information not explicitly requested, is not permitted. Legal steps are expressly reserved against the senders of so-called spam mails which violate this prohibition.

5. Validity of this disclaimer

If parts or individual formulations within this text do not comply with the current legal situation, or no longer comply or do not comply in full therewith, this shall not affect the other parts of the document in terms of their content and validity.
