# Vaultex

> Personal finance tracker for income and expenses, with interactive Safety Labs demonstrating idempotency, concurrency locking, and balance protection on a live API.

Vaultex is a React 19 progressive web app (PWA) backed by a live finance API. Public pages describe the project; authenticated areas manage transactions, analytics, and hands-on backend safety demos. The app supports offline read-only access to cached data; write operations require a network connection.
