Cookie Policy
The cookies we set, and why there are so few.
LAST UPDATED 2026-08-02
The short version
Red Cardinal sets a small number of cookies, all of them necessary. We do not run advertising or third-party analytics cookies.
What we set
Authentication. When you sign in, Supabase sets a session cookie so you stay signed in and so the server can tell whether you are a member. Removing it signs you out.
Preferences. If you change your theme or reading width, that choice is stored against your account rather than in a cookie.
What we do not set
No advertising cookies. No cross-site trackers. No third-party analytics at the time of writing. If that changes, this page changes first and we will say so.
Managing cookies
You can clear cookies in your browser. Clearing the authentication cookie signs you out; nothing else breaks.
