Privacy Policy
Last updated: March 2026
What we collect
We collect your email address and the collection data you import. Collection data includes card names, quantities, conditions, and purchase prices you provide. We do not collect payment card numbers — payments are processed by Stripe.
How we use it
Your collection data is used to compute price alerts, risk signals, and sell recommendations. Your email address is used to send alert notifications (Player and Investor tiers only) and transactional messages. We do not sell your data or share it with third parties for marketing.
Third-party services
CardMind uses Supabase (database and authentication), Stripe (payments), Resend (transactional email), and Scryfall (card and price data). Each service operates under its own privacy policy.
Data retention and deletion
You can export or delete your data at any time from the Settings page. Deleted accounts are purged within 30 days.
