Features & Capabilities

1Deck keeps every loyalty card you own in one place and gets the right barcode in front of the cashier's scanner in about three seconds.

Open the app, tap the card, hold up the screen. That is the whole flow, and it works with the phone in airplane mode. There is no account to create, nothing to sign in to, and no server involved.

WHAT IT DOES

- Add a card by picking the shop from a built-in catalogue, then scan its barcode with the camera, import it from a photo you already have, or type the number in by hand.
- Shows a large, high-contrast barcode on a white background and pushes the screen to full brightness automatically, so it scans on the first try even under bad checkout lighting.
- Favourite the cards you use every week. They pin to the front of the deck and get a one-tap shortcut row.
- Search your deck, or sort it by name or by when you last used a card.
- Recognised shops get their logo on the card automatically, straight from the catalogue built into the app. No lookup, no network.
- Use one of your own photos as a card's logo for anything the catalogue does not know.
- Back up every card, custom logos included, to a single file you can carry to a new phone and import there.
- Available in English and Czech.

WHAT IT DOES NOT DO

No account. No ads. No analytics. No tracking. No crash reporting. No cloud database of your cards. Your card numbers live in a file on your phone and stay there. The only way one leaves the device is if you export a backup yourself and choose where to send it, because the app has no server to send anything to.

FREE, AND FREE MEANS FREE

Every feature is available to everyone. There is an optional one-time "support the developer" purchase in the menu. It unlocks nothing at all. It is only there if you want to say thanks.

1Deck is not affiliated with, endorsed by, or sponsored by any of the retailers whose loyalty programmes it can store. Brand names and logos are the property of their respective owners and appear only to help you identify your own cards.
