Software that does one job, and does it well.

CardKeeper

Every loyalty card you own, in one place — without an account, a cloud, or a company reading your shopping habits.

Albert Heijn, Zalando, Gamma, the works — CardKeeper keeps their barcodes on your phone instead of in a drawer full of plastic. Add a card by scanning it, and everything else — name, code, logo, color — gets filled in for you. Everything stays on your device.

What it does

01

One guided scan adds the whole card

Line the card up in the on-screen frame, photograph the front (and the back too, if you like), and CardKeeper reads the barcode and store name off the photos for you — just confirm or fix anything it couldn't work out.
02

Automatic branding

Recognized retailers get their logo automatically; anything else falls back to a color you choose, or your own picture.
03

Nothing leaves your phone

No account, no server, no sync. Cards live in a local database — CardKeeper has no way to see them, and neither do we.
04

Encrypted backup, on your terms

Export every card to a single password-protected file and store it wherever you like — Drive, a USB stick, doesn't matter — then restore it on a new phone whenever you need to.
05

Home screen widgets

Pin your most-used card straight to your home screen, or add a swipeable widget that shows a barcode the moment you tap it — no need to open the app at the register.
