One cookie
The site sets a single cookie, tb_session. It holds a signed identifier that says
which account is signed in, nothing else, and it is marked HttpOnly so a script on the page
cannot read it.
How long it lasts
Thirty days, or until you sign out, whichever comes first.
What there is not
No analytics cookie, no advertising cookie, no third-party script that could set one. Pages that do not need a sign-in set nothing at all.
