Right of information and cancellation
You have the right at any time to inquire about the personal data collected free of charge and without delay. You may also revoke your consent to the use of your personal information with effect for the future. For this please contact the service provider specified in the imprint.

Privacy policy (general)

When accessing our website, general information (so-called server log files) is automatically recorded. These include u.a. the web browser you are using as well as your operating system and your internet service provider. These data do not allow any conclusions about your person and are statistically evaluated by us to improve our website technically and in terms of content. The collection of this information is necessary in order to deliver the content of the website correctly.

The use of the website is basically possible without providing personal data. Insofar as personal data (such as name, address or e-mail addresses) are collected, this is always done as far as possible on a voluntary basis. These data will not be disclosed to third parties without your explicit consent.

Insofar as a contractual relationship is to be substantiated, designed or changed in content, or you submit a request to us, we will collect and use personal data from you to the extent necessary for this purpose (inventory data). We collect, process and use personal data as far as necessary to enable you to use the website (usage data). All personal data will only be stored as long as this is necessary for the stated purpose (processing of your request or execution of a contract). Tax and commercial retention periods are taken into account by us. On the instructions of the competent authorities, we must provide information about this data (inventory data) on a case-by-case basis, as far as this is necessary for law enforcement purposes, security, fulfillment of the statutory duties of the constitutional protection authorities or the Military Shielding Service or for the enforcement of intellectual property rights.

We expressly point out that data transmission on the Internet (eg in the case of communication by e-mail) can have security gaps. Before accessing data can not be fully protected.

The use of contact data published in the context of the imprint obligation by third parties for the purpose of sending unsolicited advertising and information materials is hereby expressly prohibited. Exempt from this are existing business relationships or you have a corresponding consent from us.

The providers and all third parties named on this website expressly reserve the right to take legal action in the event of the unsolicited sending of advertising information. The same applies to the commercial use and disclosure of the data.



1. Liability for content

As a service provider we are responsible according to § 7 Abs. 1 TMG for own contents on these sides according to the general laws. According to §§ 8 to 10 TMG, however, we as a service provider are not obliged to monitor transmitted or stored external information or to investigate circumstances that indicate illegal activity. Obligations to remove or block the use of information under general law remain unaffected. A liability in this regard, however, is only possible from the date of knowledge of a specific infringement. Upon notification of appropriate violations, we will remove this content immediately.

2. Liability for links

This website contains links to external websites of third parties on whose contents no influence can be taken. Therefore, no guarantee can be given for these external contents. The respective provider or operator of the pages is always responsible for the contents of the linked pages. The linked pages were checked for possible legal violations at the time of linking. Illegal content was not recognizable at the time of linking. However, a permanent content control of the linked pages is not reasonable without concrete evidence of an infringement. Upon notification of violations, such links will be removed immediately from this website to the infringing site.

3. Copyright

The content and works created by the service providers, their employees and authorized third parties on these pages are subject to German copyright law. The reproduction, processing, distribution and any kind of exploitation outside the limits of copyright require the prior written consent of the respective author or creator. Downloads and copies of this site are for private, non-commercial use only. As far as the contents on this side were not created by the operator, the copyrights of third parties are considered. In particular contents of third parties are marked as such. If you should still be aware of a copyright infringement, we ask for a note. Upon notification of violations, such content will be removed immediately.
