Cookies

Short version: the service sets four cookies it cannot work without, and it sets marketing cookies only if you say yes.

Cookies we need

These keep you signed in and make sign-in and account-connection safe. They are set on this site only, are never shared with anyone, and the law does not require your consent for them.

Cookie What it does How long
__Host-session Keeps you signed in. Until you sign out, or 7 days at most; also expires after 2 hours without use.
__Host-login Ties a sign-in you started to the browser you started it in. A few minutes, deleted when sign-in completes.
__Host-authz Remembers which assistant asked you to sign in, so you land back in it. A few minutes, deleted when you pick a sign-in method.
__Host-connect Ties an account connection you started to the browser you started it in. A few minutes, deleted when the connection completes.

None of them holds personal data. Each is a random identifier that only this service can read.
