1. Website content

The author accepts no responsibility for the currency, accuracy, completeness or quality of the information provided. Liability claims against the author for material or non-material damages resulting from the use or non-use of the information provided or from the use of incorrect or incomplete information are strictly excluded unless the author can be shown to have acted with wilful intent or gross negligence. All offers are subject to change without notice and without obligation. The author expressly reserves the right to change, extend or delete parts or all of the pages without separate notice or to discontinue publication temporarily or permanently.

2. References and links

As we operate pages with the possibility to include links to other pages and have no influence whatsoever over the design and content of any such linked pages, we expressly distance ourselves from all content on any linked pages on this server and make no claim to ownership of the content of said linked pages.

3. Copyright and trademark law

The author endeavours in all publications to observe the copyrights to graphics, sound files, video sequences and texts used, to use graphics, sound files, video sequences and texts that he created himself, or to make use of royalty-free graphics, sound files, video sequences and texts. All brands and trademarks referred to on this website and protected by third parties as the case may be are subject without limitation to the provisions of the applicable law on trademarks and the proprietary rights of the registered owner in question. Mere reference to trademarks must not be construed as meaning that trademarks are not protected by third party rights. Copyright to published material created by the author remains solely with the author of the pages. The reproduction or use in other electronic or printed publications of such graphics, audio files, video sequences and texts is not permitted without the express consent of the author.

4. Data protection

If the website offers users the opportunity to enter personal or company data (e-mail addresses, names, addresses), the user discloses such data on an expressly voluntary basis. Users are also permitted to withhold such data or to enter a pseudonym – insofar as this is technically possible and reasonable – when using or paying for all the services offered. The use of contact data published as part of the site notice or similar data, such as postal addresses, phone and fax numbers as well as e-mail addresses by third parties for the mailing of not expressly requested information is not permitted. Legal steps against senders of spam mails in violation of this prohibition are expressly reserved.

5. Legal validity of this liability disclaimer

This liability disclaimer is deemed to be part of the website containing a link to this page. If parts or individual formulations of this text do not comply with current legislation, no longer do so, or do not do so fully, the content and validity of the remaining sections of the document shall remain unaffected.
