This is a personal income-and-expense tracker: users register or sign in, enter transactions, and view them in a protected dashboard with summaries, category charts, a calendar, filters, and budget information. The dashboard is the main workflow coordinator; transaction entry and deletion write to Firebase Realtime Database, while authentication state and account actions are provided through a shared context. Source excerpts confirm the principal routes, component rendering, and writes. The dashboard’s database read implementation is only partially shown, so that relationship is marked unverified.
