What is this?
Monthly Finance Tracker is a personal monthly budgeting tool built to give you a clear picture of your income, expenses, standing orders, and credit card activity — all in one place, with no accounts, no servers, and no subscriptions.
How does it work?
Everything runs entirely in your browser. Your data is never sent anywhere — it lives only on your device. When you save, you download a .json file to keep yourself. When you want to continue, you import that file back in. You can also export a formatted .xlsx spreadsheet at any time.
✓ No account needed
✓ No data leaves your device
⚿ Optional encryption
Privacy first
Muirmorrow does not collect, store, or process any of your financial data. There are no analytics, no cookies, no tracking scripts. Your numbers are yours alone. Optional file encryption (AES-256-GCM) is available so that even your saved .json file is unreadable without your password — a password Muirmorrow never sees and cannot recover.
