About This Project

FamilyKhata is a personal project: an offline-first family ledger for expenses, loans and savings, built with React Native and Supabase.

How it works:

  • SQLite queue and sync engine with conflict detection
  • A PostgreSQL schema of 28 tables protected by 100 row-level-security policies
  • Every amount encrypted on the device (XChaCha20-Poly1305), so the server never stores plain figures
