Cashflow Monitor

Local, offline personal cashflow, bills, and account balance projection tracker.

Cashflow Monitor answers one question: will I have enough, and when will I not? Enter your accounts, your bills, your income and the transfers between them. The extension projects every balance forward day by day and shows you where it dips — before it happens, not after. WHAT IT DOES • Balance projection — every account, day by day, with a net-worth total line. Pick any past or future date and see where you stood, or will stand. • Ledger — every projected and real entry in one list, filterable by date, account, category and amount. Edit a single occurrence without disturbing the recurring rule behind it. • Forecast — eight checks over the months ahead: accounts going negative, balances under their threshold, bills that will not clear, unfunded card payments, possible duplicates, income that has not arrived, unusually large expenses, and spare cash sitting somewhere it could help. Each one tells you what it would take to fix, and can create the covering transfer for you. • Questions — 21 questions about your own money, completed from dropdowns. "How much did I spend on Groceries last month?" "What is the lowest my checking account will get?" Every answer opens onto the exact entries behind it. • Credit cards, loans and mortgages — APR, minimum payments, statement dates and payoff projection, with transfers whose amount follows the account instead of a number you maintain by hand. • Multi-currency — each account in its own currency, with a real exchange rate on transfers that cross between them. • Export anything to Excel. WORKS OFFLINE, BY DEFAULT Your data is stored on your device using the browser's own extension storage. Nothing is sent anywhere unless you switch on one of the optional features yourself: • Google Drive or OneDrive backup — your choice, off by default. • SimpleFIN bank linking — read-only, and only if you provide your own token. • Exchange rates — only with your own API key. There is no account to create, no server of ours to trust, and no advertising or analytics of any kind. This build contains no AI and makes no calls to any AI service. Open it from the toolbar icon or in Chrome's side panel, alongside whatever else you are doing.
