Data protection

Exclusion of liability

1. Content of the online offering

The author makes no guarantee that the information is up-to-date, correct, or complete and accepts no liability for its quality. The author will accept no liability claims relating to material or non-material harm caused by the use or failure to use the information provided or by the use of incorrect and incomplete information, unless the author can be demonstrated to have acted with intent or gross negligence.
All quotations are subject to confirmation and are non-binding. The author expressly reserves the right to amend, supplement or delete parts of pages or the entire quotation or to temporarily or permanently cease publication without notice.

2. References and links

No liability will be accepted for direct or indirect links to third-party web sites (“Hyperlinks”) that are outside the author”s scope of responsibility unless the author was aware of the content and it would have been technically feasible and reasonable for the author to prevent the use of illegal content.
The author hereby expressly declares that no illegal content was identifiable on the linked sites at the time the links were created. The author has no influence over the current and future design, content or authorship of the linked sites. The author therefore specifically dissociates itself from all content on any linked sites that may have been changed after the links were created. This applies to all links and references within the author”s own Internet offering and for third-party entries in the guest books, discussion forums, directories of links and mailing lists created by the author and in any other forms of database to the content of which external write access is possible. Sole liability for illegal, incorrect or incomplete content and in particular for harm arising from the use or failure to use such information lies with the provider of the referenced site, not the provider of the site that only refers to the respective publication by means of links.

3. Copyright and trademarks

The author makes every attempt to comply with the copyright terms of the images, graphics, sound documents, video sequences and copy used, to use images, graphics, sound documents, video sequences and copy that the author has created itself or to use licence-free graphics, sound documents, video sequences and copy.
All brands and trademarks cited within the Internet offering that may be protected by third-parties are fully subject to applicable trademark law and the property rights of the respective registered owners. Citation alone is not sufficient reason to conclude that trademarks are not protected by third-party rights!
The copyright for published items created by the author itself remains exclusively with the author of the pages. Reproduction or use of such graphics, sound documents, video sequences and copy in other electronic or printed publication is not permitted without the express consent of the author.

4. Data protection

Where it is possible to enter personal or business information (e-mail addresses, names, postal addresses) in Internet offerings, divulgence of this information by the user is on a strictly voluntary basis. Insofar as is technically feasible and reasonable, all the services offered may be used and paid for without providing such information or by providing anonymised information or a pseudonym. The use by third parties of contact details published in the credits or similar information, such as postal address, telephone and fax numbers and e-mail addresses, to transmit information that has not been specifically requested is not permitted. In the event of violation of this prohibition, we expressly reserve the right to take legal proceedings against senders of so-called spam mails.

5. Validity of this exclusion of liability

This exclusion of liability is to be regarded as part of the Internet offering from which this page is linked. Should parts or individual formulations of this text fail to comply, cease to comply or fail to comply fully with the applicable legal basis, the content and validity of the remaining parts of the document shall be unaffected.
