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.
