With the activation of the confirmation link you give us your consent for the use of your personal data according to Art. 6 para. 1 lit. a GDPR. When you register for the newsletter, we store your IP address entered by the Internet Service Provider (ISP) as well as the date and time of registration in order to be able to track any possible misuse of your email address at a later point in time.

Newsletter dispatch via MailChimp

Our email newsletters are sent via the technical service provider The Rocket Science Group, LLC d/b/a MailChimp, 675 Ponce de Leon Ave NE, Suite 5000, Atlanta, GA 30308, USA (, to whom we forward the data you provided when registering for the newsletter. This transfer takes place in accordance with Art. 6 para. 1 lit. f GDPR and serves our legitimate interest in the use of an effective, secure and user-friendly newsletter system. Please note that your data is usually transferred to a MailChimp server in the USA and stored there.
MailChimp uses this information for the dispatch and statistical evaluation of the newsletter on our behalf. For evaluation purposes, the emails sent contain so-called web beacons or tracking pixels, which represent one-pixel image files stored on our website. In this way it can be determined whether a newsletter message has been opened and which links have been clicked. Mailchimp uses web beacons to automatically generate general, non-personal statistics about the response behavior to newsletter campaigns. On the basis of our justified interest in the statistical evaluation of the newsletter campaigns for the optimization of advertising communication and the better orientation towards recipient interests, the web beacons are used in accordance with Art. 6 para. 1 lit. f. GDPR, but also data of the respective newsletter recipient (email address, time of retrieval, IP address, browser type and operating system) and used. This data allows individual conclusions to be drawn about the newsletter recipient and is processed by Mailchimp to automatically generate statistics that show whether a particular recipient has opened a newsletter message.
If you wish to deactivate data analysis for statistical evaluation purposes, you must unsubscribe from the newsletter.
According to Art. 6 para. 1 lit. f GDPR, MailChimp may also use this data itself for its own legitimate interest in designing and optimizing the service to meet its needs and for market research purposes in order to determine, for example, from which countries the recipients come. However, MailChimp does not use the data of our newsletter recipients to write to them or pass them on to third parties.
In order to protect your data in the USA, we have concluded a data processing agreement with MailChimp based on the standard contractual clauses of the European Commission to enable the transfer of your personal data to MailChimp.
