Scandio is a loyalty-card manager for 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 pull it up in two taps and let the cashier scan it off the screen.

The app is built around the idea that this kind of data has no business leaving your phone. There is no account, no sign-in, and no cloud. Everything you add stays in the app’s private container on your device.

What it does

Privacy

Scandio collects nothing, transmits nothing, and contains no analytics, advertising identifiers, or third-party SDKs. The full privacy policy covers what the app stores locally, how camera and photo-library access is used, and how the optional Apple Intelligence category suggestion works.

Source code

Scandio is open source. The full source — SwiftUI views, SwiftData model, barcode renderers, backup format — lives at github.com/andrzejsiemion/scandio-ios.
