About the atlas
Privacy
A plain description of what this site collects, which is very little.
This is a reading site. You do not need an account to use it, and it does not ask for personal details unless you choose to write to the editors.
What we collect
The site sets no cookies of its own, runs no advertising and loads no analytics or tracking scripts. It does not collect names, email addresses or health details through its pages. The contact form does not send anything to us by itself: it opens your email program with a message addressed to the editors, and nothing is sent until you send it.
What third parties see
Like any website, this one is delivered by a hosting provider, and ordinary technical request data such as your IP address and browser type passes through it. The page fonts are loaded from Google Fonts, so the font provider also receives a standard request when a page opens. We do not control how those providers handle that technical data, and you can read their own policies. Links to sources take you to other websites, which have their own policies.
If you write to us
If you email the editors, we use your address only to reply and to correct a card where you found a mistake. We do not sell or share messages. Please keep medical details out of any message. See how we check facts for what happens to a correction, and the about page for who runs the site.
Changes
If this policy changes, the date at the top of the page changes with it. You can start again from the glossary or the home page whenever you like.
