Card Forge

Data & Storage

Everything you make lives only in this browser. This page is where you back it up, check how much space it’s using, and — if you ever need to — start over.

Storage

Storage usage isn’t available in this browser.

Backup & restore

You haven't backed up your vault yet. A backup is a single JSON file with every card, set, collection, and trade — the only way to move your vault to another device or recover it if something goes wrong.

Danger zone

Permanently deletes every card, set, collection, and trade on this device. Back up your vault first — there is no undo.
