Data Privacy

1. Contents of the website

The author assumes no liability for the actuality, accuracy, completeness or quality of the information provided. Claims for liability against the author, which refer to damages of a material or ideal nature, which were caused by the use or non-use of the information offered or by the use of faulty and incomplete information, are principally excluded, insofar as no wilful intent or gross negligence may be proven on the part of the author. All offers are subject to confirmation and not binding. The author expressly reserves the right to change, supplement, delete parts of the pages or the whole offer without separate notification or to suspend the publication either finally or for a certain period of time.

2. References and links

In case of direct or indirect references to third party Internet sites (“Links”), which are outside of the area of responsibility of the author a liability obligation would come into force exclusively in the event, in which the author has gained knowledge of the contents and it is technically possible and would be deemed reasonable for him, to prevent the use in the event of unlawful contents. The author expressly declares that at the time when the links were set no illegal contents were recognisable to the sites to be linked. The author has no influence whatsoever on the actual and future design, the contents or the authorship of the linked sites. Therefore, the author hereby expressly distances himself from all contents of all linked sites, which were changed after the link was set. This stipulation applies for all links and references set within the own Internet offer. The provider of the site to which reference was made shall have sole responsibility, not the person, who via links merely refers to the respective publication, in case of illegal, faulty or incomplete contents and in particular for damages resulting from the use or non-use of such information offered.

All trademarks and brands mentioned within the Internet offer and if applicable protected by third parties are subject to an unlimited extent to the provisions of the respective applicable brand law and the rights of property of the respective registered owners. Just because they are mentioned the conclusion must not be drawn that trademarks are not protected by rights of third parties! The copyright for published objects created by the author personally remains exclusively with the author of the pages. It is not permitted to reproduce or use such graphics, sound documents, video sequences and texts in other electronic or printed publications without the express prior consent of the author.
