are the operators (hereinafter “we” or “operators”) of the website (hereinafter referred to as the “Website”) and the services offered thereon and thus responsible for the collection, processing and use of personal data.

When collecting data, the principle of data economy is of great importance to us. We collect and process personal data only insofar as you have given us consent for this, or the legislator expressly permits us or prescribes us or you allow us to do so. Further, we will explain what information we collect, how we use it, and what rights you have over us in relation to the use of your information:



1.           Personal data

Personal data is specific information about personal or material circumstances of an identified or identifiable natural person. This includes, for example, your civil name, your address, email address, your telephone number or your date of birth. Furthermore, this also includes company-related data.

2.           Collection

a) when visiting our website

Unless otherwise stated in the following sections, no personal data is collected, processed or used when using our websites.When visiting our website, our servers temporarily store every access in a log file. The following data will be collected without your intervention and stored on a server in Germany in a data center commissioned by us with automated data removal after 30 days at the latest:

– the name and URL of the requested file,
– Referrer URL (the previously visited page),
– date and time of request,
– The browser version you are using.

If you contact us via the contact form or fill in our complaint form online, we will store your e-mail address, name, country and your IP address. We work with the software provider “Form Assembly” to create the online form structure that allows you to submit your request. The personal data that you enter via the format will be collected so that the relevant department can process your request to contact you with the subject matter of the request.

b ) when subscribing to a newsletter

For sending the newsletter, we use the so-called double opt-in procedure, i.e., we will only send you a newsletter by e-mail if you have previously explicitly confirmed to us that we should activate the newsletter service. We will then send you a notification e-mail asking you to confirm that you wish to receive our newsletter by clicking on a link in this e-mail.

By opening the first automatically generated confirmation e-mail for receiving the newsletter and opening each newsletter e-mail, additional data will be collected and sent to us for the administration of the newsletter. These include, for example:

– which subscriber has opened the newsletter or left-clicked on it (incl.
Number of clicks)
– Date of registration and, if applicable, subscribers to the newsletter
have unsubscribed
– Any returns that have occurred (for example, if the e-mail account is overcrowded or not

We only evaluate this data for purely statistical purposes in order to further optimize our offers. By subscribing to the newsletter you consent to the use of this data. Your data will not be used for any other purpose.

The personal data collected about you within the scope of the e-mail newsletter will only be used internally to optimize and deliver the newsletter you specifically request. A sale or a transfer of your personal data to third parties for the purpose of advertising, market or opinion research does not take place.

Should you later no longer want to receive newsletters from us, you can withdraw your consent to this at any time. An informal written notification to the contact details listed at the end of this document (e.g. e-mail, letter) is sufficient. Of course, you will also find a link to unsubscribe in every newsletter.

3.          Storage

We store and process your personal data on servers in Germany. We, as well as our designated data centers, protect your information through technical and organizational security measures to mitigate risks associated with loss, misuse, unauthorized access, and unauthorized disclosure and alteration of such data. For example, firewalls and data encryption are used, as well as physical access restrictions and authorization controls for data access. We take steps to ensure that the personal information we collect is accurate and up-to-date.You can revoke your consent to the use or use of your personal data informally at any time.

Your personal data will only be passed on to third parties or otherwise transmitted if this is necessary for the purpose of the contract or if you have given your prior consent.
We will not share your data with third parties without your consent. The contrary shall only apply if there is a legal obligation to do so (e.g. information to certain authorities in the context of statutory requirements) or if this is necessary for the enforcement of our rights, in particular for the enforcement of claims arising from the contractual relationship with you.

2.           Integration of services and contents of third parties

It is possible that third party content on our website, such as videos from YouTube, maps from Google Maps, RSS feeds or graphics from other websites are included. This always presupposes that the providers of this content (“third party providers”) receive the IP address of the users, since without the IP address they would not be able to send the contents to the browser of the respective user. The IP address is therefore required for the presentation of this content. We endeavor to use only that content for which respective providers use the IP address only for the delivery of the content. However, we have no influence on it if the third-party provider uses the IP address e.g. for statistical purposes. Insofar that we are or become aware, we will inform users about it.
