First Principles is a fan-built editorial encyclopedia. We use Supabase for sign-in (Google OAuth, optional). We use Stripe for one-time First Principles AI lifetime payments. We use PostHog for anonymous analytics. No personal data is sold.

If you sign in, the only profile data we store is the email and display info returned by Google OAuth, plus your in-app activity (ratings, favorites, Short Takes). You can delete your account at any time from settings.

Stripe handles payment information end-to-end. First Principles never sees or stores card numbers.
