1. What we use
Plotwise uses only the cookies and local-storage items strictly required to operate the Service. We do not set advertising or third-party tracking cookies.
- Authentication session(Supabase) — keeps you signed in across pages. HttpOnly. Required.
- Theme preference— remembers light / dark mode. Local storage. Functional.
- Impersonation cookie(admin only) — present only while a support agent is viewing your account. Audit-logged. HttpOnly.
2. Analytics
Plotwise uses PostHog for product analytics (pageviews and a small set of behavioural events). PostHog is configured incookieless mode: no analytics cookies are set, and user identifiers are kept in browser memory only (not in localStorage or cookies). Person profiles are created only for signed-in users via their account id; anonymous landing-page visitors are not associated with a profile.
3. Browser controls
You can clear or block cookies from your browser settings. Blocking the authentication session cookie will sign you out and prevent future sign-ins until you re-enable it.
