Cookie Policy
Last updated: August 5, 2026
PreviewAPI sets two cookies, both of them strictly necessary to sign you in, and both set by BetterAuth rather than by us. There are no advertising, analytics, or cross-site tracking cookies — nothing below profiles you or is shared with anyone — so we do not show a cookie banner.
better-auth.session_token7 daysKeeps you signed in. Set when you sign in, and readable only by our server (httpOnly).better-auth.state5 minutesSet only while you are being redirected to Google or GitHub, so the reply can be matched to the sign-in that started it. It is discarded as soon as sign-in finishes or the 5 minutes lapse.Over HTTPS both names carry the browser's __Secure- prefix, so in your browser's inspector they read __Secure-better-auth.session_token and __Secure-better-auth.state.
What is not a cookie
Your light/dark theme preference is kept in your browser's local storage, under pa-theme, not in a cookie. It never leaves your device and is never sent to us, which is why it is not in the table above and why it does not follow you to another browser.
Managing cookies
You can clear or block cookies in your browser settings. Blocking them will sign you out and prevent you signing back in, since both cookies exist to carry the sign-in — and because captures are made from the dashboard during beta, that leaves nothing usable.
