Scandio

All your loyalty cards on your iPhone. Scan a barcode, show it at the till. Nothing leaves your device — no account, no sync, no tracking.

Scandio keeps all your loyalty cards in one place on your iPhone. Add a card by scanning its barcode, give it a name and a colour, and the next time you're at the checkout you open it in two taps and let the cashier scan it off the screen.

Everything stays on your device. No account, no sign-in, no cloud, no tracking. The app has no analytics, no advertising identifiers, no crash reporters, and no third-party SDKs.

WHAT YOU CAN DO

• Add cards by scanning a barcode with the camera or typing the number manually • Render seven barcode types: EAN-13, EAN-8, ITF, QR, Code 128, PDF417, and Aztec • Show any card full-screen with an automatic brightness boost so it scans cleanly even on supermarket scanners • Pin favourites to the Quick Access carousel at the top of the home screen • Sort alphabetically, by date added, or by last used • Search by card name • Pick a tile colour from the brand palette or with a custom hex picker • Attach a store logo from your photo library • Choose a category icon from twelve emoji, or let the on-device language model suggest one

BUILT-IN STORE RECOGNITION

Scandio recognises common store names and fills in the brand colour and a built-in icon automatically — Biedronka, Lidl, Rossmann, IKEA, Auchan, Carrefour, Decathlon, MediaMarkt, and many more.

APPLE INTELLIGENCE

On supported iPhones running iOS 26 or later, Scandio uses Apple's on-device Foundation Models framework to suggest a category icon from the store name you typed. The suggestion runs entirely on your iPhone — no prompt or response is logged or transmitted.

BACKUP AND RESTORE

Built-in export creates a .scandiobackup file with all your cards, colours, logos, and preferences embedded. AirDrop it to a new iPhone or save it anywhere iOS lets you save documents. On import, Scandio asks how to handle duplicates — skip, merge, or add as new — and you can set a default for the dialog if you'd rather not be asked.

PRIVACY BY DESIGN

Scandio collects nothing and transmits nothing. Loyalty cards, photos, and preferences live only on your device, in the app's private container. The full privacy policy is at siemion.pro/scandio/privacy.
