App #Stocard Alternative --> Catima

Stocard is a mobile app that allows users to store their loyalty cards digitally, helping to reduce wallet clutter. It enables users to collect rewards points and access discounts by scanning their loyalty card barcodes directly from their phones.

Unfortunately this app is no longer available and alternative app proposed did not convince me. (Klarna)

So I found an interesting open Source app (Catima) that work properly and with less privacy concerns (only problem is that card image is not automatically included but you can take loyalty card photo and override problem)

About backups are done locally and, from my perispective, I decisevely prefer this approach.
