Church Finance

Church Finance is a Flutter application that helps small churches record income and expenses, share a single ledger across a small team of trusted members, and produce monthly reports — all without requiring an internet connection. The app is designed offline-first and crypto-first: data lives in a local encrypted SQLite database, backups are encrypted with an Argon2id-derived key, and sync between devices uses both Nearby Connections (Bluetooth/Wi-Fi Direct) for local sync and a WebSocket relay server for cross-network real-time sync.
