“We never see, keep or share your transactions. Everything is stored only on your device. Refreshing, isn't it?”
Sounds very interesting! How does this work? Does the app use the API on the device itself or does it get the data via - as you call it - app-servers, thus having transaction data passing through your systems?
All the other solutions have a collecting server which makes me hesitant about using those, hence build one myself but yours looks really slick 👍🏻
