Privacy Policy

Prophet is a graded trading-card collection tracker. This policy explains what we collect and how we use it. We do not sell your personal data.

What we collect

  • Account: your email address and a display name.
  • Collection: the cards you add (cert numbers, grades, cost basis, notes).
  • Activity: cards you scan and alerts you create.
  • Device: a push-notification token if you enable notifications.
  • Diagnostics: anonymous app analytics and crash reports.

How we use it

To run the app: authenticate you, store your collection and alerts, send notifications you opt into, and identify cards from photos or cert numbers you submit. Anonymous scan activity may be aggregated into community trends; it is not tied to your identity.

Service providers

We use Supabase (authentication + database hosting), Expo (push notifications), and third-party model and grading-data providers to identify cards and estimate grades from images or cert numbers you submit. These providers process data only to deliver the service.

Data retention + deletion

We keep your data while your account is active. You can delete your account at any time in Settings > Account > Delete account, which permanently removes your data and sign-in.
