Word of honour-Media concepts

The information given here complies with the following legal obligations: § 6 und § 7 Teledienstgesetz (TDG)
§ 4 Abs. 3 Bundesdatenschutzgesetz (BDSG)
§ 312c Bürgerliches Gesetzbuch (BGB)
§ 1 BGB-Informationspflichten-Verordnung (BGB-InfoV)

1. Content of online product offer: The author assumes no warranty or representation as to the relevance, accuracy, completeness or quality of the information provided. Liability claims against the author in respect of material or immaterial damage caused by the use or non-use of the information offered or by inaccurate or incomplete information are in principle ruled out provided that there is no provable culpable intent or gross negligence on the author's part. All offers are non-binding and subject to confirmation. The author expressly reserves the right to change, supplement or delete these pages in part or in whole, for a temporary period or permanently, without prior notification.
2. References and links: In the case of direct or indirect references to other websites ("links") that do not come within the sphere of responsibility of the author, an obligation to liability would only become effective if the author had knowledge of content that is illegal and he was technically and in any other way capable of preventing its use. The author hereby explicitly declares that at the time the link was created, no illegal content was apparent on the web pages to be linked. The author has no influence on the current or future design, contents or the authorship of the linked pages. For this reason, the author expressly dissociates him/herself from all contents of all linked sites which were altered after the link was established. This stipulation applies to all links and references given on the company's own website as well as to third-party entries in guest books, discussion forums and mailing lists set up by the author. In the event of illegal, erroneous or incomplete contents and particularly in the event of damage caused by the use or non-use of information of this kind offered in this way, only the provider of the site to which reference is made can be held liable and not the person who merely made reference to each publication by means of the links.
3. Copyright and trademarks: In all publications, the author endeavours to observe the copyright of the graphics and texts that are utilised, to use graphics and texts of his own authorship, or to take recourse to licence-free graphics and texts. All trade and brand names that are named within the Internet information supply offer, and that are protected by a third party where applicable, are subject without exception to the stipulations of the relevant legal trademark registration, and to the ownership rights of the relevant registered owner. It should not be concluded that a trademark is not protected by the rights of the third party, even when one is doing no more than simply mentioning it! The copyright for all published objects that have been provided by the author himself belongs exclusively to the author of the site. The duplication or reworking of such graphics, sound documents, video sequences and texts in other electronic or print publications is not permitted without the explicit permission of the author.
4. Data protection: Insofar as there is the opportunity for entering personal or business data (e-mail addresses, names and addresses), the disclosure of this information by the user takes place explicitly on a voluntary basis. The use and payment of all services offered is – as far as technically possible and acceptable – possible without visitors having to disclose such data or enter anonymous data or a pseudonym. The third-party use of contact data publicised as part of this imprint or comparable information, such as postal addresses, telephone and fax numbers and e-mail addresses, for the purpose of sending information that was not explicitly requested is prohibited. The operators of this website expressly reserve the right to take legal action in the event of unsolicited spam mails being sent.
5. Validity of this disclaimer: This disclaimer is to be considered a part of this Internet offer, which is referred to on this page. If parts or individual formulations of this text should not, no longer or not completely correspond to the valid legal position, the remaining parts of the document remain unaffected in their contents and validity.
