Cookies
Last updated October 11, 2026
PantaCal uses a handful of cookies and browser settings, all of them to make the site work or remember a choice you made. None are for advertising, analytics or tracking, and none are set by other companies' scripts.
Cookies
sb-…-auth-token
Keeps you signed in. Set by our sign-in provider, Supabase.
How long: Until you sign out, or about a year
pc_school
Remembers which school you picked, so the site shows its colors and copy before you sign in.
How long: 1 year
pc_invite
Only if you used the close-friend password: lets that browser reach sign-up while sign-up is invite-only. Stores a scrambled token, not the password.
How long: 90 days

Notifications
If you turn on notifications, your browser installs a small helper (a service worker) from PantaCal that shows them and opens the app when you tap one. It doesn't cache pages or watch what you do. Turning notifications off in Settings, or removing PantaCal from your home screen, removes it.
Why there's no cookie banner
Cookie banners exist to ask permission for cookies a site doesn't strictly need, like analytics and advertising. Everything above either keeps the site working (signing in) or remembers something you chose (your school, dark mode). Privacy rules treat both as exempt from consent, so there's nothing to ask. If we ever add anything that isn't in these two groups, we'll ask you first and list it here.
Clearing them
Signing out removes the sign-in cookie. You can clear the rest in your browser's settings at any time. PantaCal still works, it just forgets your school and display choices.
