Privacy
What this site records about the people who read it, which is very little.
Reading this site needs no account and asks nobody who they are. The servers that deliver the pages keep the ordinary request logs every web server keeps, and those are held by the hosting providers for their own operation.
Page views are counted with Google Analytics. Whether anything is stored on your device while that happens is your decision: the strip at the foot of the page asks once, your answer is kept in your browser and sent nowhere, and it can be changed below whenever you like. Say no, or say nothing, and the count still happens — carrying nothing that could recognise you again. Either way what Google receives is the address of the page, the language it was read in, an approximate country worked out from an IP address it does not keep, and the kind of device — never your name, and never anything you typed. No advertising signals are sent, and none of it is used to build a profile of you.
Choosing a language in the header writes one cookie, NEXT_LOCALE. It holds the two-letter code of the language you chose and nothing else, it is kept for a year, and it exists so that a later visit opens in that language. Deleting it does no harm.
Signing in is optional and unlocks nothing. If you sign in — with a Google account, or with a link sent to your email — the address is stored by the authentication service the site uses, Supabase, and shown back to you in the header. It is not used to send mail and is not passed on to anyone.
Pages, images and audio are served by Vercel and Supabase, whose servers see the requests. The links under Sources lead to PubMed, doi.org, ClinicalTrials.gov and publishers’ own sites, each with its own privacy terms.
Under the General Data Protection Regulation you may ask what is held about you and have it corrected or deleted.
