1. Online and Website Content

The author does not assume any liability or grant any guarantee for the up-to-datedness, topicality, correctness, completeness or quality of the information provided here. Liability claims against the author that pertain to any type of material or non-material damage arising from the use or non-use of the information presented here or arising from the use of erroneous or incomplete information are explicitly excluded, provided there is no demonstrable proof of willful or gross negligence on the part of the author.

All offers are subject to change and are non-binding. The author explicitly reserves the right to change, supplement or delete the entire content or part(s) of the website thereof without prior or separate notice. The author also reserves the right to temporarily or permanently suspend or terminate publication without prior or separate notice.


2. References and Links

In the case of direct or indirect links to external third-party websites that are not under the author's sphere of responsibility, liability would come into force only if the author had prior knowledge of the content and it was technically feasible and reasonable to prevent usage of the linked site in the event of illegal or illicit content.

The author hereby explicitly declares that at the time the links were added, there were no discernible illegal or illicit contents on the linked page(s) or site(s). The author has no influence or control whatsoever on the current or future design, layout, contents or authorship of the linked/referenced page(s) or site(s). Therefore, the author explicitly disassociates himself from any and all contents of any and all linked/referenced page(s) or site(s) that are changed after the link has been added. This declaration applies to all links and references within the author's own website as well as to any third-party entries posted to visitor's books, discussion forums, link directories, mailing lists and any other forms of databases set up by the author which permit external write access to their contents. In the event of illegal, erroneous or incomplete content, and particularly in the case of damage arising from the use or non-use of such content, the provider/author of said linked site assumes sole responsibility and liability for the content; liability in such cases is not assumed by the person who merely linked said contents on his or her published website.


3. Copyright and Trademark Law
The author endeavours to observe the copyrights of the graphics, audio files, video sequences and texts used, to use self-created graphics, audio files, video sequences and texts, or to use royalty-free graphics, audio files, video sequences and texts.
All brand names and trademarks mentioned within the online/website content and those which, if applicable, are protected by third parties, are subject without restriction to the provisions and specifications of the valid trademark laws and possessor rights of the respective registered owner. The mere mentioning of a brand name or trademark shall not be interpreted as meaning that the brand name or trademark is not protected by third party rights!
The author retains the sole copyright(s) for published objects created by the author of the website himself. The reproduction, duplication or use of such graphics, audio files, video sequences or texts in other electronic or printed publications is not permitted without the express consent of the author.


4. Data Privacy and Protection
If the online/website content provides the option of entering personal or company data (e-mail addresses, names, addresses), the user shall disclose such data on a strictly voluntary basis. The utilization and payment of any and all services offered – provided it is technically feasible and reasonable – is permitted without entering such data or by entering anonymous data or a pseudonym. Third parties are not permitted to use contact data published in the imprint or in comparable information, such as postal addresses, telephone numbers, fax numbers and e-mail addresses, for sending information that has not been expressly requested. In the event of violations against this prohibition, we reserve the right to take legal action against the sender(s) of "spam" mail.


5. Legal Validity of this Liability Disclaimer
This liability disclaimer is to be regarded as a component of the online/website content which has referred this page to the user. If sections or individual formulations of this text do not, no longer, or do not completely comply with currently valid law, the content and validity of the remaining parts of the document remain unchanged and unaffected.
