Privacy

Heart of the Cards is a free place to learn and play. This page says what is stored and why.

Without an account

Your decks, settings and duel history live in your browser only. The site records anonymous page views and finished duels (format, deck names, result) with a random id that is not linked to you. In duels against the computer your game choices (which cards you used, held back or targeted, and how the duel ended) are saved anonymously to make the computer opponent play better.

With an account

Signing in with Google gives the site your name, email address and profile picture. They are used to show who you are, to let friends find you, and to keep your saved decks and duel history across devices. Nothing is posted anywhere and nothing is sold or shared with advertisers.

Where it is kept

Accounts and saved data are stored with Supabase in the European Union. You can delete your account and everything with it by writing to r.laith27@gmail.com.
