Webdesign and Development:



1. Content of the Online Offer

In order to keep the information on this website as up-to-date, factually correct and unambiguous as possible, every effort is made during the creation of this website to ensure this. Despite all efforts, it is possible that unintentional errors may occur. The website content is offered by the responsible person without obligation and to the exclusion of any guarantees or assurances. This also applies to all websites to which reference is made by means of (hyper)links.

Insofar as there is no demonstrable intentional or grossly negligent fault on the part of the responsible party, liability claims against the responsible party relating to damage of a material or immaterial nature caused by the use or non-use of the information provided or by the use of incorrect and incomplete information are excluded.

2. 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 person responsible, a liability obligation exists exclusively in the case where the person responsible has knowledge of the contents and it would be technically possible and reasonable to prevent the use in the case of illegal contents.

The responsible person hereby expressly declares that at the time the links were created, no illegal content was identifiable on the linked pages. The responsible person has no influence on the current and future design, content or authorship of the linked pages. It is not reasonable to carry out a permanent control of the contents of the linked pages without concrete evidence of a violation of the law. Therefore, we hereby expressly distance ourselves from all contents of the 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 the guest books, discussion forums and mailing lists set up by the responsible party. If any damage occurs by the use of information presented there, only the author of the respective pages might be liable, not the one who has linked to these pages. This also applies to illegal, incorrect or incomplete content. We will remove such links as soon as we become aware of any infringements of the law.      

3. Copyright and Trademark Law

The responsible person endeavors 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 the responsible person himself or to use license-free graphics, sound documents, video sequences and texts.

All brand names and trademarks mentioned on the website 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 owners. The mere mention of a trademark does not imply that it is not protected by the rights of third parties.

The contents and works created by us on these pages are subject to German copyright law. The copyright for any material created by the author is reserved. Without the express consent of the responsible person, the reproduction or use of such works, in particular graphics, sound documents, video sequences and texts, is not permitted. In the case of a lawful use of the information and pictorial material made available on this homepage, this must take place with indication of the copyright source. We reserve the right to withdraw permission for the reproduction of copyrighted material at any time. This applies in particular if, in our opinion, the right to reproduce such material is exercised in a manner contrary to our interests or if instructions for the protection of copyright are not consistently observed.

We do not assume any warranty or liability for freedom from third party rights in connection with this authorization.

4. Limitation of Liability and Exclusion of Liability

This website was compiled with the greatest possible care. 

Provided that there is no demonstrable intentional or grossly negligent fault on the part of the responsible party, liability claims against the responsible party which relate to damages of a material or immaterial nature and which were caused by the use or non-use of the information presented or by the use of incorrect and incomplete information are excluded.

All offers are subject to change and non-binding. We expressly reserve the right to change, supplement or delete parts of or all pages without prior notice, or to temporarily or permanently cease publication or to attach other conditions of use.
