Content of the online offer

The website operator assumes no liability for the topicality, correctness, completeness or quality of the information provided. Liability claims against the website operator relating to material or immaterial damage caused by the use or non-use of the information provided or by the use of incorrect or incomplete information are excluded, unless there is evidence of wilful intent or gross negligence on the part of the website operator.

All offers are subject to change and non-binding. The website operator expressly reserves the right to change, supplement or delete parts of the pages or the entire offer without prior notice or to temporarily or permanently cease publication.

References and links

In the case of direct or indirect references to external Internet pages ("links") which lie outside the area of responsibility of the website operator, a liability obligation would only come into force in the event that the website operator was aware of the content and it would have been technically possible and reasonable for him to prevent use in the event of illegal content.

The website operator hereby expressly declares that at the time the links were created, no illegal content was recognisable on the linked pages. The website operator has no influence of any kind on the current and future design, content or authorship of the linked pages. Therefore, he hereby expressly distances himself from all contents of all linked pages that were changed after the link was set. This statement applies to all links and references set within the own Internet offer as well as to external entries in guest books, discussion forums and mailing lists set up by the website operator.

For illegal, incorrect or incomplete contents and in particular for damages arising from the use or non-use of such information, only the website operator of the page to which reference was made is liable, not the person who merely refers to the respective publication via links.

Copyright and trademark law

The provider endeavours to observe the copyrights of the graphics, sound documents, video sequences and texts used in all publications, to use graphics, sound documents, video sequences and texts created by himself or to make use of licence-free graphics, sound documents, video sequences and texts.

All brands and trademarks mentioned within the Internet offer and possibly protected by third parties are subject without restriction to the provisions of the applicable trademark law and the ownership rights of the respective registered owners.

The mere fact that a trademark is mentioned shall not lead to the conclusion that it is not protected by the rights of third parties. The copyright for published objects created by the website operator himself remains solely with the website operator. For such graphics, sound documents, video sequences and texts, the author grants you the specific right of use to make a private copy for personal purposes. Any duplication or use of objects such as images, diagrams, sounds or texts in other electronic or printed publications is not permitted without the author's agreement.

Validity of this legal disclaimer

If sections or individual terms of this statement are not legal or correct, the content or validity of the other parts remain uninfluenced by this fact.

Property right infringement

If you suspect that one of your property rights has been infringed by this website, please inform us immediately by e-mail so that we can rectify the situation quickly. This can avoid unnecessary costs.

The more time-consuming involvement of a lawyer to issue the website operator with a warning notice, which is subject to a charge, therefore does not correspond to the website operator's actual or presumed will.
