  1. Website Content
    The author assumes no liability for the topicality, correctness, completeness or quality of the information provided. Liability claims against the author, which refer to material or immaterial nature caused by use or disuse of the information or the use of incorrect and incomplete information are excluded, unless the author is not intentional or grossly negligent fault. All offers are subject to change and non-binding. The author expressly reserves the right to change, supplement or delete parts of the pages or the entire offer without prior notice or to discontinue the publication temporarily or permanently.

  2. Hyperlinks
    As a content provider, we are responsible for our "own content", which we make available for use, in accordance with general legislation pursuant to Section 5 (1) of the Media Services State Treaty. These own contents are to be distinguished from cross-references ("links") to the contents provided by other providers. By the cross-reference we hold in this respect "foreign contents" ready for use. We are only responsible for this external content if we have positive knowledge of it (i.e. also of illegal or punishable content) and it is technically possible and reasonable for us to prevent its use (§5 Para. 2 Mediendienste-Staatsvetrag). However, "links" are always "living" (dynamic) references. When the link was first set up, we checked the external content to see whether it might give rise to any civil or criminal liability. However, we are not obliged to constantly check the content to which we refer in our offer for changes that could give rise to a new responsibility. Only if we determine or are informed by others that a specific offer to which we have provided a link triggers civil or criminal liability, the reference to this offer will be removed, insofar as this is technically possible and reasonable for us. The technical possibility and reasonableness will not be influenced by the fact that even after access from our homepage has been prohibited, the illegal or criminal offer can be accessed from other servers. We use this disclaimer here with the kind permission of the Data Protection Commissioner Berlin, from whose website we have derived it for our purposes and who also makes it available to anyone who would like to use it.
