Technology Stack

This website was built with Astro.js, a modern framework for static websites. Astro.js itself does not collect or process any user data.

Data Sharing and Recipients

Your personal data is not transmitted to third parties except:

  • when we have explicitly indicated this in the description of the respective data processing (e.g., Telegram bot for contact forms),
  • when you have given express consent in accordance with Art. 6 para. 1 sentence 1 lit. a GDPR,
  • the disclosure is necessary in accordance with Art. 6 para. 1 sentence 1 lit. f GDPR for the assertion, exercise, or defense of legal claims and there is no reason to assume that you have an overriding legitimate interest in not disclosing your data,
  • in the event that there is a legal obligation for disclosure in accordance with Art. 6 para. 1 sentence 1 lit. c GDPR, and
  • insofar as this is necessary in accordance with Art. 6 para. 1 sentence 1 lit. b GDPR for the processing of contractual relationships with you.

We also use carefully selected external service providers to process our services. They are bound by our instructions and are regularly monitored by us. These are service providers for web hosting (DigitalOcean), web analytics (Umami), contact form processing (Telegram), and the provision of fonts (Bunny Fonts). The service providers will not pass this data on to third parties.

Data Security

We take appropriate technical and organizational measures in accordance with Art. 32 GDPR, taking into account the state of the art, implementation costs, and the nature, scope, circumstances, and purposes of processing, as well as the varying likelihood and severity of risk to the rights and freedoms of natural persons, to ensure a level of protection appropriate to the risk.

For security reasons and to protect the transmission of confidential content, this website uses SSL/TLS encryption. You can recognize an encrypted connection by the fact that the address bar of the browser changes from “http://” to “https://” and by the lock symbol in your browser bar.

Duration of Storage of Personal Data

The duration of storage of personal data is based on the relevant statutory retention periods (e.g., from commercial and tax law). After the respective period expires, the corresponding data is routinely deleted.

If data is required for contract fulfillment or contract initiation, or if we have a legitimate interest in continued storage, the data will be deleted when it is no longer required for these purposes or when you have exercised your right of revocation or objection.

Data from contact inquiries will be deleted as soon as the inquiry has been finally processed and there are no legal retention obligations.
