Processing of personal data when visiting this website

When you visit this website, certain information is automatically sent by the browser on your device to our server. This may include your IP address, date and time of access, the name and URL of the requested file, the referrer URL, as well as the browser and operating system used.

This data is processed for the following purposes: ensuring a smooth connection to the website, evaluating system security and stability, and for administrative purposes. The legal basis is Art. 6 para. 1 lit. f GDPR (legitimate interest in the secure and stable operation of the website).

Use of Cloudflare

We use services of Cloudflare Germany GmbH, c/o Design Offices München Atlas, Rosenheimer Straße 143C – 8th floor, 81671 Munich, Germany, and Cloudflare Inc., 101 Townsend St, San Francisco, CA 94107, USA ("Cloudflare"), to secure and optimize our website (e.g. content delivery network, DDoS protection, and performance optimization).

In this context, personal data such as IP address, requested URLs, date and time of access, amount of data transferred and browser information may be processed and transferred to Cloudflare servers in the European Union and in third countries (in particular the USA). Cloudflare is certified under the EU‑US Data Privacy Framework; in addition, EU Standard Contractual Clauses are used.

The legal basis is Art. 6 para. 1 lit. f GDPR (legitimate interest in a secure, high‑performance and abuse‑resistant operation of our website).

Cookies and similar technologies

This website uses only technically necessary cookies. These are small files set by Cloudflare (our CDN and security provider) solely for the purposes of network routing, DDoS protection, and load balancing. No tracking, analytics, profiling, or marketing cookies are used on this website. Because we do not use any non‑essential cookies, no cookie consent banner is displayed.

The legal basis for technically necessary cookies is § 25 para. 2 no. 2 TTDSG in conjunction with Art. 6 para. 1 lit. f GDPR (legitimate interest in the secure and stable operation of the website).

Contact

If you contact us by email or using a contact form, we will process the personal data you provide (e.g. name, email address, content of the inquiry) in order to handle your request and for potential follow‑up questions. The legal basis is Art. 6 para. 1 lit. b GDPR (performance of a contract or pre‑contractual measures) or Art. 6 para. 1 lit. f GDPR (legitimate interest in answering inquiries).

Our website is hosted on Cloudflare Pages, a service of Cloudflare Inc., 101 Townsend St, San Francisco, CA 94107, USA (EU contact: Cloudflare Germany GmbH, c/o Design Offices München Atlas, Rosenheimer Straße 143C – 8th floor, 81671 Munich, Germany). Cloudflare acts as a data processor on our behalf; data processing is governed by Cloudflare’s Data Processing Addendum, which meets the requirements of Art. 28 GDPR.

Storage period

Unless a more specific storage period is stated in this Privacy Policy, we process and store personal data only for as long as necessary to achieve the purposes described or as required by statutory retention obligations.

Obligation to provide data

You are not legally or contractually obliged to provide personal data. However, to technically display the website, it is necessary that your browser transmits certain data (such as your IP address); otherwise, our website cannot be accessed properly.
