2. Hosting and delivery via Cloudflare
This website is delivered via Cloudflare (Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA). To deliver a page to you, Cloudflare processes technically necessary data on every request: your IP address, date and time, the requested URL, browser and system information (user agent) and, where applicable, the previously visited page (referrer). Cloudflare also uses this data to protect the site against attacks and abuse.
The legal basis is Art. 6(1)(f) GDPR. My legitimate interest is providing the website securely, quickly and reliably. A data processing agreement (Data Processing Addendum) is in place with Cloudflare. Data may be transferred to the USA. Cloudflare is certified under the EU-US Data Privacy Framework, which is covered by an adequacy decision of the European Commission. Standard contractual clauses are also in place. I do not analyse access data on a personal level.

3. Fonts
The fonts (Geist, Geist Mono and Newsreader) are hosted on this server. Loading the page does not connect to Google or any other font provider.
4. Topic suggestions via Tally
Via “Missing something?” you can suggest topics. The form is hosted by Tally (Tally BV, Belgium). No data is transferred until you open the link and fill in the form. Tally processes what you enter (your suggestion and, if you provide it, your email address) as well as technical data such as your IP address. According to Tally, the data is stored in the EU.
The legal basis is Art. 6(1)(a) GDPR (your consent by submitting) and, as far as handling your suggestion is concerned, Art. 6(1)(f) GDPR. I only use the information to review your suggestion and reply if needed, and delete it when it is no longer needed for that. More: Tally privacy policy
5. Contact by email
If you email me, I process your email address and the content of your message to reply (Art. 6(1)(f) GDPR). I do not share this data and delete it once the matter is settled, unless retention obligations apply.
6. Links to studies and other sites
The articles link to studies, e.g. on PubMed or publisher sites. Simply reading an article does not send any data to these sites. Only when you click a link does the privacy policy of that site apply.
7. Your rights
You have the right to
- access your stored data (Art. 15 GDPR),
- rectification (Art. 16), erasure (Art. 17) and restriction of processing (Art. 18),
- data portability (Art. 20),
- object to processing based on Art. 6(1)(f) GDPR (Art. 21),
- withdraw consent with effect for the future (Art. 7(3)).
Just send me an email. You can also lodge a complaint with a data protection supervisory authority, e.g. in your country of residence or at my place of residence.
