Privacy Policy

Last updated May 31, 2026

CardStonks ("we", "us") is a service operated by CMO Associates LLC, a limited liability company based in the United States. This policy explains, in plain English, what we collect and what we do with it.

What we collect

  • Your email address and authentication identifiers (so you can sign in).
  • Photos of cards you upload to identify or value.
  • The cards, decks, and collection data you save.
  • Scan history and quota usage.
  • A Stripe customer ID if you subscribe. We never see or store your card number — Stripe handles all payment details.

How we use it

  • Run the app and identify the cards you scan.
  • Sync and display your collection across devices.
  • Process subscription payments and apply your quota.
  • Diagnose bugs and improve the service.

Third parties we share data with

  • Lovable Cloud — hosting and database.
  • Stripe — payments and subscriptions.
  • Google — if you use Google Sign-In.
  • Google Analytics — anonymous usage analytics (pageviews and product events) so we can improve the app.
  • AI providers — uploaded card photos are sent to AI vision models to identify the card.
  • Card data sources — Scryfall, pokemontcg.io, YGOPRODeck, and optcgapi.com supply card metadata and prices.

We do not sell your personal data to anyone.
