Liability notice:

Responsibility for contents

Despite careful control of the contents, we do not assume any liability for the contents of external links. The operators of the linked pages are solely responsible for their content.


Exclusion of use
We expressly object to the use of contact data published within the framework of the imprint obligation by third parties for the purpose of sending unsolicited advertising and information material. We expressly reserve the right to take legal action in the event of the unsolicited sending of advertising information, for example through spam mails.


We ask, in case of problems of competition law, domain law, copyright or similar cases, to contact us in advance, so that unnecessary costs or legal disputes can be avoided. In case of rightly objected passages we guarantee an immediate removal. The involvement of legal counsel at this early stage is not necessary. The costs arising from a legal warning will be rejected as unfounded, without prior contact with us, in the sense of the duty to mitigate damages and, if necessary, a counterclaim for violation of the aforementioned provisions will be filed.

Our web pages and their contents are subject to German copyright law. Unless expressly permitted by law, any form of use, reproduction or processing of copyrighted works on our websites requires the prior consent of the respective copyright holder. Individual reproductions of a work are permitted for private use only. The materials on these pages are copyrighted and any unauthorized use may violate copyright laws.
