Why we built this
We had simple apps.
They worked.
For years, loyalty card apps just… worked. You scanned a barcode. The app stored it. At the register, you pulled it up. Done.
Then the apps we relied on got acquired. The new owners "modernised" them. Suddenly we needed accounts. Then cloud sync we never asked for. Then ads. Then a paywall to use features that used to be free. Then our cards started disappearing because someone's server had a bad day. Then the app wanted our email address to display a barcode.
We got tired of watching simple tools get cannibalised by companies that treated our cards as a funnel instead of a feature.
So we built a new one, like the old ones. Properly. For ourselves, and for anyone else who misses when apps did one thing and respected your device enough to stay out of the cloud.
Open source, simple by design
Every line, auditable.
