Liability for content

The articles available on the website are for general information purposes only and are not intended to provide advice in specific cases. We endeavor to ensure that all information and data contained on the website is correct and up-to-date in accordance with Section 7 (1) of the German Telemedia Act (TMG). However, no liability is assumed for the correctness, completeness, topicality or quality of the information and data provided in accordance with § 8 to 10 TMG. Liability for the content of the retrievable information is excluded, except in the case of deliberate or grossly negligent misinformation. Obligations to remove or block the use of information in accordance with general legislation remain unaffected by this. However, liability in this respect is only possible from the time of knowledge of a specific infringement. As soon as we become aware of such infringements, we will remove this content immediately.


Liability for links

We are not responsible for the content of websites that can be reached via a hyperlink. The operators of the linked pages are solely responsible for their content. We expressly do not adopt the content of these websites as our own and therefore cannot guarantee the correctness, completeness and availability of the content. We have checked the third-party content when the link was first created to determine whether it could give rise to civil or criminal liability. However, we are not obliged to constantly check the content to which we refer on our website for changes that could give rise to new liability. Only if we determine or are informed by others that a specific offer to which we have provided a link triggers civil or criminal liability will we remove the reference to this offer, insofar as this is technically possible and reasonable for us.



The content and works on this website created by the operator of this site are subject to German copyright law. All contributions by third parties are identified as such. Duplication, processing, distribution and 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. Copies of these pages are only permitted for private use, but not for commercial purposes.


Data protection

The use of our website is generally possible without providing personal data. Insofar 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.

In connection with your access, data that may allow identification (e.g. IP address, date, time and name of the requested file) is temporarily stored on our server for data security purposes. An evaluation, except for statistical purposes in anonymized form, does not take place.
