This website collects and processes visitors' personal data only to the extent technically necessary, or where visitors actively get in touch. Collected data is only shared with third parties where required to provide the website or required by law.

This data is not merged with other data sources and is used solely to ensure secure and stable operation of the website. Legal basis: Art. 6 (1)(f) GDPR (legitimate interest in a functioning website).
The fonts (Google Fonts) and the JavaScript library (Supabase client) used on this website are hosted and served locally on our own server. No connection is made to servers operated by Google, jsDelivr, or any other third party, and no data is transmitted to these providers.
This website offers a contact form. Data entered there (name, email address, message) is sent to a database hosted by Supabase Inc. (with servers in the EU, Frankfurt region) upon submission and stored there in order to process the request. This database automatically notifies the site operator by email of new requests; that email is sent via the Resend service (Resend, Inc., USA), which transmits the data entered in the form (name, email address, message) to that service. Alternatively, you can also get in touch by email or phone; data shared that way is likewise used exclusively to process your request. Legal basis: Art. 6 (1)(b) GDPR (processing a request prior to or as part of a possible contractual relationship) or Art. 6 (1)(f) GDPR (legitimate interest in responding to inquiries).
Posts and images in the blog section of this website are likewise delivered via Supabase Inc. (database and file storage, servers in the EU, Frankfurt region). No personal data of visitors is processed in doing so.

This website only uses technically necessary cookies or local storage (e.g. to keep the login session active in the test pages area). These are not used for analytics or tracking of usage behaviour.
For security reasons, this website uses SSL/TLS encryption. You can recognise an encrypted connection by the "https://" prefix in your browser's address bar.
