2. References and links
In the case of a direct or indirect reference to an external website (“hyperlinks”) which is out of the author’s control, legal liability would only come into effect if the author has knowledge of the content and if it is technically possible and reasonable for him to prevent the use in case of illegal content.
The author expresses explicitly herewith that at the time of the link setting no illegal content was seen on the website to which the link was set. The author has no influence over the actual and future creation, the contents or the authorship of the linked website, which is why the author explicitly dissociates himself from all content of linked websites which have been changed after the link was set. This statement is valid for all links within IBC Heiztechnik’s internet offer as well as for outside comments in visitor’s books, discussion forums and mailing lists established by the author. Only the provider of the page on which the link referred to guarantees against illegal, incorrect or incomplete content and particularly for damages, which were caused by the use or non-use of this information, not the author of the page which links to the respective publication.

3. Copyright and trademark law
The author is endeavouring to respect the copyright laws of the images, audio files, video sequences and texts used in all publications and to use images, audio files, video sequences and texts he made himself or to use images, audio files, video sequences and texts, which are free.
All protected brands and registered trademarks within the online offer and should it arise mentioned through any 3^rd party laws are subject to the regulations of the relevant trademark law and to the registered owner’s ownership laws. Just because of this notice it can’t be concluded that brands are not protected by 3^rd party laws.
The copyright for public objects made by the owner remains with the author of the pages. Duplication or use of such images, audio files, video sequences and texts in other electronic or printed publications is not allowed unless with the author’s explicit agreement.

4. Data protection
If the option to input personal or business data (e-mail-addresses, names, addresses) occurs within the offer this input occurs on a voluntary basis of the user. Payment for all services provided is, if technically possible and reasonable, also allowed without this information, by using anonymous data or a pseudonym. The use of contact data like addresses, phone numbers and fax numbers as well as e-mail-addresses by 3^rd parties to send non-requested information is not permitted. Legal measures will be taken against the dispatch of so called “spam-mails” in the case of offence against this ban.
