We share data with the following subprocessors solely to operate the service:
Stripe — payment processing and subscription management. Stripe receives your email address and billing information. Stripe's privacy policy is available at stripe.com/privacy.
Resend — transactional email delivery. Resend receives your email address and the content of system-generated emails sent to you.
Railway — cloud infrastructure provider. Your account data and collection data are stored on Railway's infrastructure. Railway's data processing addendum is available at railway.app.
Better Stack — error monitoring. Better Stack receives scrubbed error diagnostics, including stack traces, request paths without query strings, and internal user IDs. We configure error reports to exclude email addresses, cookies, request headers and bodies, and collection data.
Scryfall and MTGJSON — card metadata (names, set codes, oracle text, imagery) is sourced from these publicly available databases. No personal data is transmitted to them.
Card-market data providers — catalog datasets may include prices attributed to TCGplayer and Card Kingdom. No personal data or collection records are sent to those marketplaces.
We do not authorize subprocessors to use your data for any purpose beyond providing their services to us.
