The contents of these pages were created with great care. While reasonable steps have been taken to ensure that the information contained is updated and accurate, krupka–stieghan makes no warranties about the accuracy of the information, assumes no responsibility for inaccuracies or mistakes in the information, and reserves the right to make changes to the products and services described in this site at any time without notice.

As a service provider we are responsible under § 7 paragraph 1 of TMG (German Teleservices Act) for ensuring that our own content on this site complies with general legislation. According to §§ 8 to 10 TMG we are however under no obligation to monitor transmitted or recorded information from external sources nor are we liable to search for circumstances that may suggest illicit activity. Obligations to remove or block access to information under the general laws remain unaffected. A liability referring to this is however only possible from the moment of actual notice of a specific infringement. Upon notification of such violations, we will remove the content immediately.

Liability for links
Our website contains links leading to external web sites operated by third parties, with content we can not influence and that we do not adopt as our own. Therefore we can not accept any responsibility for their content. The respective provider or operator is always responsible for the contents of any linked Site. The linked pages were checked for any legal irregularities at the time of the establishment of the link and no illegal contents were recognisable at that point of time. However, permanent checking of the linked pages in terms of content is not reasonable without specific evidence indicating a legal infringement. Upon notification of violations, we will remove such links immediately.

The reproduction, modification, distribution or any kind of exploitation outside the limits of copyright require the written consent of its respective author or creator.

In particular contents of third parties are marked as such. Should you still have reason to believe that a copyright violation has occurred despite the precautionary measures taken, we kindly request that you inform us.
