One explanation a week
What it is, how it works, and why it matters — with the version it was tested against printed on every piece.

Strictly necessary
Always on
Remembers this choice and keeps the site working. Cannot be turned off, because without it the site would ask you this on every page.
Analytics
Counts which explanations get read, in aggregate. We use it to decide what to write next, not to identify you.
Functional
Embedded things from other sites, such as a video in an article. Off means you get a placeholder and a link instead.
Advertising
This site carries no ads and no sponsored explanations, so nothing currently uses this. It stays here so the choice is yours if that ever changes.
