Disclaimer

Liability for Content
As a service provider, we are responsible for our own content on these pages in accordance with § 7 (1) TMG. However, we are not obliged to monitor transmitted or stored third-party information or investigate circumstances indicating illegal activity. Obligations to remove or block the use of information under general laws remain unaffected. Liability in this respect is only possible from the moment we become aware of a concrete infringement. Upon becoming aware of such legal violations, we will remove the content immediately.

Liability for Links
This website contains links to external websites of third parties, over whose content we have no influence. We therefore cannot assume liability for such external content. The respective provider or operator of the linked pages is always responsible for their content. The linked pages were checked for potential legal violations at the time of linking. Illegal content was not identifiable at that time. Permanent monitoring of linked pages without concrete indications of legal violations is unreasonable. If we become aware of any legal violations, we will remove such links immediately.

Copyright
All content and works created by the website operator on these pages are subject to German copyright law. Reproduction, editing, distribution, and any kind of use outside the limits of copyright law require prior written consent. Downloads and copies of this site are permitted for private, non-commercial use only.
