MyFin Budget

MyFin is a self‑hosted personal finance platform that combines a web interface, a REST API and an Android app for budgeting, expense tracking, and financial forecasting. Users can record transactions manually or import them in bulk, split entries, and organize accounts, categories, and entities to reflect income and spending patterns. The system supports multilingual operation in English and Portuguese and offers rule‑based auto‑categorization to streamline data entry.

The budgeting component follows a month‑by‑month approach, while statistical views provide historical patrimony evolution and multi‑year forecasts. Investment tracking is available in beta, and the interface includes selectable light and dark themes. All features are delivered under a GPL‑3.0 license, with no subscription or proprietary tier, allowing users to retain full control over their data on their own infrastructure.
