Liability for contents

The contents of our pages were created with the greatest care. However, we cannot guarantee that the contents are correct, complete and up-to-date. As a service provider, we are responsible for our own content on these pages in accordance with § 7 (1) TMG (German Telemedia Act) and general laws. According to §§ 8 to 10 TMG we are not obliged to monitor transmitted or stored information from third parties or to investigate circumstances that indicate illegal activity. Obligations to remove or block the use of information according to general laws remain unaffected by this. However, liability in this respect is only possible from the time of knowledge of a concrete infringement. If we become aware of any such legal infringements, we will remove the content in question immediately.

Liability for links

Our online offer contains links to external websites of third parties, on whose contents we have no influence. Therefore, we cannot assume any liability for these external contents. The respective provider or operator of the sites is always responsible for the contents of the linked sites. The linked pages were checked for possible legal violations at the time of linking. Illegal contents were not identified at the time of linking. However, a permanent control of the contents of the linked pages is not reasonable without concrete evidence of a violation of the law. If we become or are made aware of any infringements, we will remove such links immediately.

Author’s right (Copyright)

The contents and works on these pages created by the site operators are subject to German copyright law (or rather, “author’s right law”). The reproduction, editing, distribution and any kind of use outside the limits of copyright law require the written consent of the respective author or creator. Downloads and copies of these pages 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 observed. In particular, third-party content is identified 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 contents immediately.


The use of our website is usually possible without providing personal data. As far as personal data (e.g. name, address or e-mail addresses) is collected on our website, this is always done on a voluntary basis, as far as possible. This data will not be passed on to third parties without your express consent. More information about data protection can be found on the page Privacy Policy.

We would also like to point out that data transmission over the Internet (e.g. communication by e-mail) can have security gaps. A complete protection of data against access by third parties is not possible.

If you wish to communicate with us confidentially, you can download our public keys for encrypted e-mails: Download the S/MIME key for info @ defrent . de >/a> or the PGP key for info @ defrent . de

The use by third parties of contact data published within the mandatory legal notice (imprint) and other contact data published on this website for the purpose of sending advertising and information material not expressly requested (UCE) is hereby expressly prohibited. The operators of the website expressly reserve the right to take legal action in the event of the unsolicited sending of advertising information, for example through spam mails.

Social Networks

On this website, you will also find buttons for social networks, such as Facebook, Twitter or Xing. These buttons implement the so-called “2-click solution” to comply with German data protection law. This means that they are initially simple graphic links. When you click on these logos for the first time, a connection to the respective social network is established and personal data can also be transferred to third parties without any further action on your part. Only after a second click, your message is sent to the social network. These data are mostly stored and processed outside of Germany or the EU. DeFrEnT has no influence on the use of this data. Therefore, if you activate a network button with your first click, you do so at your own risk.
