The score serves the deck—not a marketplace.
DeckFoundry uses deterministic, explainable rules to evaluate legality, construction, playstyle, and card synergy. Marketplace or affiliate relationships never influence card scores or deck generation.
Signed-in collections and saved decks are kept separate by account. DeckFoundry does not store your Google profile name or email address in its user database. You can export your collection and delete your application data from within DeckFoundry.
