2. Hosting and server logs

This website is hosted by Netlify (USA). Netlify also resolves the domain name, encrypts the connection and caches the pages.

When you visit this website, your browser automatically sends technical data to Netlify: IP address, timestamp, requested URL, HTTP status code, bytes transferred, referrer, browser and operating system. Netlify processes this data in its server logs. This data is technically necessary for operating the site securely.

A data processing agreement is in place with Netlify. Transfers to the USA are based on the EU-US Data Privacy Framework, with standard contractual clauses as a fallback.

Legal basis: Art. 6(1)(f) GDPR (legitimate interest in the secure and stable operation of the website).

3. Cookies

This website does not use cookies and stores nothing in your browser. It counts visits with Fathom Analytics, a service that uses no cookies and creates no personal profiles (see section 4). No data is processed for advertising purposes.

This website has no newsletter and no forms and asks you for no data.

8. Links to other websites

This website links to UX&I, X, LinkedIn, GitHub and the websites of my own projects. The share links at the end of an article open X or LinkedIn. These websites are only loaded when you follow a link. Their providers’ own privacy policies apply there.
