The browser asks once for permission to use the camera and remembers the answer. In Chrome on Android, tap the icon to the left of the address bar, then Permissions → Camera → Allow, and reload the page. If the camera is not listed there, check Android Settings → Apps → Chrome → Permissions → Camera.

The camera also needs a secure connection, so the address has to start with https. Another app or another tab holding the camera open will block it too — close them and try again.

Lay the card flat on a plain surface in even light and keep the whole card inside the outline; a card held in the hand bends just enough to change the picture. Glare on a holo is the usual culprit — tilt the phone rather than the card.

The number in the bottom corner settles most of the rest, so a photo where that corner is sharp is worth more than a bright one. When the app still cannot tell, it asks for AI help by itself: up to ten times a day on Free, without a limit on Family Plus. If it picked the wrong print, tap the right one and the correction is remembered for next time.

Prices come from a public database: the Cardmarket trend price in euros and the TCGplayer market price in dollars, both through TCGdex, refreshed every night. Which of the two the app shows is a setting.

They are estimates of what a card has been selling for, not an offer and not a valuation. Condition, a different print or a local market can put the real price far from them.

Purchases made in the Play Store reach the app through RevenueCat, which can take a minute. Signing out and back in usually makes the plan appear.

If it still does not, write to us from the address on the account and say when you bought it and which plan; we put it right by hand. A refund, if you would rather have that, is handled by Google.

Settings → Your data. “Backup” writes one file with everything of this household — profiles, cards, wants, themed sets, binders, decks, badges and the history — and “Restore” reads it back into another account.

For a spreadsheet or another app, the CSV export of the collection and of the wish list sits next to it, and CSV can be imported again. None of this costs anything.

Settings → Account → Delete account, then type the account’s email address and the password. Everything goes at once, the scan photos included. The delete-account page explains it step by step, and says what to do if you cannot sign in any more.
