Kasirin Aja

A volunteer project, deliberately not built to make money. It is aimed at people running food stalls, corner shops, and home businesses who need to record what comes in and goes out without subscribing to anything.

Data is kept locally on the device in SQLite, so the app works fully without an internet connection and no business data is sent anywhere. No ads, no paid tier, no locked features.

One design decision was made specifically for these users: the number pad is custom-built with large keys and arithmetic operators inside it, so adding up several items can happen directly in the amount field. The letter keyboard stays the device's own.

Maintenance is not scheduled. Fixes happen when a real user reports something broken, not because a calendar says so.
