Privacy Policy
Last updated: June 20, 2026
Mauldron is a hobby project for Magic: The Gathering Commander players. This policy explains what we collect and why. We keep it minimal on purpose.
What we collect
- Account info — your email address, an optional display name, and a securely hashed password (we never store your password in plain text).
- Your content — the decks, collections, and playgroup/game data you create in the app.
- Operational logs — standard server logs (e.g. IP address, request times) used to run the service, debug issues, and prevent abuse.
How we use it
- To provide the deck-building, analysis, and collection features you ask for.
- To authenticate you, send password-reset and email-verification messages.
- To protect the service against abuse (rate limiting, spam prevention).
We do not sell your personal data, and we don't show third-party advertising.
Third-party services
- Email — transactional emails (password reset, verification) are delivered via Resend.
- Card data — card information and prices come from Scryfall; combo and synergy data from Commander Spellbook and EDHREC. Browsing these does not share your identity with them.
- Card scanner (optional) — if you use the camera scanner, an image may be sent to Google Cloud Vision for text recognition only. Images are not retained for this purpose beyond the recognition request.
