Quorum does not use traditional HTTP cookies. Instead, we use browser local storage — a similar technology that stores small pieces of data in your browser. This page lists every key we store, what it contains, and how to manage it.

quorum_cookie_consentStrictly Necessary
Records your cookie consent choices (necessary, functional, analytics). Required to respect your preferences.
Duration: Until manually cleared

Remembers your light / dark mode preference so the interface loads in your chosen theme without a flash.
Duration: Until manually cleared
quorum_user_emailAuthentication
Persists your email address after signing in so the interface can recognise you across page loads without requiring a fresh session check.
Duration: Until you sign out or clear storage
quorum_device_idFunctional — consent required
An anonymous identifier generated on your device. Used to group decision sessions created on this device before you sign in, so history is preserved at sign-up.
Duration: Until manually cleared
quorum_session_idsFunctional — consent required
A local list of decision session IDs created on this device. Allows the home screen to show your recent decisions without a server request.
Duration: Until manually cleared
sb-*-auth-tokenAuthentication
Supabase authentication session token. Maintains your signed-in state across browser sessions.
Duration: Session, or until Supabase token expiry
Analytics
Quorum does not currently use any third-party analytics, advertising trackers, or cross-site tracking technologies. The analytics toggle in your consent preferences is reserved for potential future use and is off by default.
Managing your preferences
You can update your consent choices at any time via the Privacy Center in app Settings. Changing your functional cookie preference will not delete existing local data — you can clear browser local storage manually via your browser's developer tools if you wish to remove all stored data immediately.
Revoking functional consent means new session IDs and device identifiers will no longer be written to your device. Previously created sessions remain accessible via their direct URL.
