Liability for content
The contents of our pages were created with utmost care. However, we cannot guarantee the accuracy, completeness and topicality of the content. As a service provider, we are responsible for our own content on these pages in accordance with the general laws pursuant to § 7 para. 1 TMG. However, according to §§ 8 to 10 TMG, we are not obliged as a service provider to monitor transmitted or stored third-party information or to investigate circumstances that indicate illegal activity. Obligations to remove or block the use of information in accordance with general laws remain unaffected by this. However, liability in this regard is only possible from the point in time at which a concrete infringement of the law becomes known. If we become aware of any such infringements, we will remove the relevant content immediately.
Liability for links
Our website contains links to external websites of third parties over whose content we have no influence. Therefore, we cannot assume any liability for these external contents. The respective provider or operator of the pages is always responsible for the content of the linked pages. The linked pages were checked for possible legal violations at the time of linking. Illegal contents were not recognisable at the time of linking. However, permanent monitoring of the content of the linked pages is not reasonable without concrete indications of a legal violation. If we become aware of any infringements of the law, we will remove such links immediately.
The contents and works created by the site operators on these pages are subject to German copyright law. Duplication, processing, distribution, or any form of commercialization of such material beyond the scope of the copyright law shall require the prior written consent of its respective author or creator. Downloads and copies of this site are only permitted for private, non-commercial use. Insofar as the content on this site was not created by the operator, the copyrights of third parties are respected. In particular, third-party content is marked as such. Should you nevertheless become aware of a copyright infringement, please inform us accordingly. If we become aware of any infringements, we will remove such content immediately.
As a rule, it is possible to use our website without providing personal data. Insofar as personal data (e.g. name, address or e-mail addresses) is collected on our pages, this is always done on a voluntary basis. This data will not be passed on to third parties without your express consent.
We would like to point out that data transmission on the Internet (e.g. communication by e-mail) can have security gaps. Complete protection of data against access by third parties is not possible.
The use of contact data published within the framework of the imprint obligation by third parties for the purpose of sending advertising and information material not expressly requested is hereby expressly prohibited. The operators of the pages expressly reserve the right to take legal action in the event of the unsolicited sending of advertising information, for example through spam mails.
