Privacy Policy
2. Provision of the Website and Server Log Files
When you access this website, the web server processes technically necessary access data. This may include, in particular, the IP address, date and time of access, the page or file accessed, amount of data transferred, browser type, operating system, referrer URL and the requesting provider.
Processing is carried out to provide the website securely and reliably and to detect attacks and technical faults. The legal basis is Article 6(1)(f) GDPR. Our legitimate interest lies in the secure and functional operation of this website. Log data is retained only for as long as necessary for operation and security and is then deleted, unless further retention is required to investigate a security incident. Our hosting service provider processes this data on our behalf.
3. Contacting Us
If you write to us using the contact form or by email, we process your details—in particular your name, email address, selected topic, message and time of contact—solely to handle your enquiry and any follow-up questions.
If the enquiry concerns initiating or performing a contract, the legal basis is Article 6(1)(b) GDPR. In all other cases, processing is based on our legitimate interest in responding to enquiries under Article 6(1)(f) GDPR. The data is deleted once the enquiry has been fully handled and no statutory retention obligations or legitimate grounds for further storage remain.
4. Newsletter with Mailchimp
We use Mailchimp to send our newsletter. Mailchimp is a service of The Rocket Science Group LLC d/b/a Mailchimp, 675 Ponce De Leon Avenue NE, Suite 5000, Atlanta, GA 30308, USA, an Intuit group company.
When you subscribe, your email address, selected language, subscription time and confirmation status are transmitted to Mailchimp and processed there to send and manage the newsletter. Processing is based exclusively on your consent under Article 6(1)(a) GDPR. We use the double opt-in procedure for confirmation. You may withdraw your consent at any time with effect for the future by using the unsubscribe link in any newsletter or by contacting us.
Mailchimp also processes data in the United States. According to Mailchimp, transfers of European data are based on the EU–US Data Privacy Framework and, where required, the European Commission’s Standard Contractual Clauses. Further information is available in the Intuit/Mailchimp Privacy Statement and the Mailchimp Data Processing Addendum.
As a rule, we retain newsletter data until you unsubscribe. After withdrawal, necessary evidence may be retained under Article 6(1)(f) GDPR for the duration of statutory limitation periods in order to demonstrate that consent was previously given.
5. External Content and Links
This website contains links to external services, including YouTube, YouTube Music, Instagram, WhatsApp, PayPal, Dialog+ and other information sites. Merely displaying such a link does not transmit data to the respective provider. Once you click it, the external provider’s privacy policy applies.
6. Cookies and Similar Technologies
In its current form, this website does not use analytics, marketing or social-media cookies and does not contain embedded social-media videos or feeds. A consent banner is therefore not currently required. If services requiring consent are added later, they will be loaded only after your express consent and this policy will be updated accordingly.
Strictly necessary storage technologies may be used where required for the operation or security of the website. The legal basis is section 25(2) TDDDG in conjunction with Article 6(1)(f) GDPR.
7. Your Rights
Subject to the statutory requirements, you have the right of access, rectification, erasure, restriction of processing, data portability and objection to processing based on Article 6(1)(e) or (f) GDPR. You may withdraw consent at any time with effect for the future.
You also have the right to lodge a complaint with a data protection supervisory authority. In particular, you may contact the Berlin Commissioner for Data Protection and Freedom of Information, Alt-Moabit 59–61, 10555 Berlin, email: mailbox@datenschutz-berlin.de.
8. Currency of This Policy
Last updated: 8 October 2026. We will update this Privacy Policy if the website, the services used or the legal requirements change.
