Cookies this site sets
| Name | Purpose | Lifetime | Who it affects |
|---|---|---|---|
survey_state |
Signed, HTTP-only. Holds a random identifier and nothing else. Which session you joined, which step you are on and your in-progress estimates are held on our server against it, so a reload does not lose them and you can reopen your results page. | 8 hours | participants |
withdraw_once |
Signed, HTTP-only. Carries your personal deletion link from the moment you finish to the results page that shows it, once. It is deleted as that page is drawn, and it is the only cookie that ever holds anything more than a random identifier. | 5 minutes | participants |
backoffice |
Keeps educators and administrators signed in (signed, HTTP-only). | 6 hours (educators) / 3 hours (administrators) | backoffice |
wee_pending_totp / pending2fa |
Carries the intermediate step of two-factor sign-in: the pending-login marker (5 minutes) and, while you are enrolling, the not-yet-confirmed TOTP secret (15 minutes). | 5-15 minutes | backoffice |
