Cookie policy

Last updated: 2026-05-07

What we use

  • Essential cookies: Supabase auth session, CSRF protection, affiliate ref attribution. These cannot be disabled while using CPG.
  • Analytics: We use Plausible, which is cookieless by design. Optionally, with your consent, we may use PostHog (privacy-first, EU-hosted) for feature flag and product analytics.

Affiliate attribution

If you visit CPG via an affiliate link (e.g. ?ref=ABC123), we set a single cookie (cpg_ref) that lasts 90 days, used solely to credit affiliates on signup.

How to manage

You can clear cookies in your browser settings at any time. Doing so will sign you out of CPG.
