About

Curo Calculator is built on the open-source Curo library, a feature-rich Dart library for instalment credit calculations, released under the MIT License. While the Curo Calculator app itself is proprietary, the core calculation engine is open-source, reflecting our commitment to the open-source community.

The source code for the Curo Calculator app is proprietary and not available in this repository. This repo provides the binaries, Flatpak manifest, and assets for Flathub integration.

• Metadata files (app.curocalc.calculator.yml, app.curocalc.calculator.desktop, app.curocalc.calculator.metainfo.xml) are provided under MIT; the icon (app.curocalc.calculator.svg) is proprietary.
