Secure session cookie

After sign-in, the site sets ctp_sess, an HTTP-only, Secure, SameSite cookie used to keep your account signed in. Browser JavaScript cannot read it.

Local browser preferences

The dashboard may use local storage to remember whether onboarding was completed and to retain non-sensitive interface preferences. This information stays in that browser unless you clear it.
