What it does.

1. Accounts

   Make an account, log in, and your balance and history are waiting for you each time you come back.
2. Transactions

   Add income and expenses with a category and description. They show up in a table you can scroll through and delete from.
3. Budgets

   Set a budget per category, then check a report that shows what you budgeted, what you've spent, and what's left.
4. Charts

   Matplotlib draws a bar chart of spending by category, so you can see where the money actually goes.
5. Storage

   Everything saves to a JSON file and loads back when the program starts, so nothing's lost between sessions.
6. Error handling

   A missing or corrupted data file doesn't crash it — the program just starts you off with empty data instead.

What's under the hood.

Built with tkinter·Matplotlib·JSON·Datetime·OS. The rest is just plain Python.

Run it on your own computer.

It's a tkinter desktop app, so it opens in its own window — it won't run in the browser. Grab the file and run it locally.

1. Make sure you've got Python 3, plus matplotlib installed.
2. Open finance.py in anything that runs Python. IDLE, VS Code, etc.
3. Run it — a window pops up. Make an account and start adding transactions.
