Financial Tracker

A private ledger that stitches every account into one honest view — net worth, cash flow, and spending, with no spreadsheet ritual on the first of the month.

The Analogy

The personal CFO that actually shows up.

Most people know their paycheck and their rent. The rest is fog — scattered cards, a 401k you log into twice a year, a checking balance that lies by two days. Budgeting apps try to help and then nag you into uninstalling them.

This is the opposite of a nagging app. It reads every account you own, reconciles the mess, and gives you one picture: what came in, what left, what's actually growing. No gamification. No guilt. Just the number.

You can't improve a finish line you can't see. The first job is measurement.
How It Works

Pull. Reconcile. Report.

Input
It pulls everything.
Syncs checking, credit, brokerage, retirement, and crypto accounts through secure aggregators so nothing is left out.
→
Transform
It reconciles the mess.
Categorizes transactions, nets out transfers, rolls up recurring bills, and marks the outliers worth a second look.
→
Output
You get one honest view.
Net worth over time, cash flow by month, category trends, and a short list of what actually moved the number.
Under the Hood

What's actually running.

Ingest Account Aggregator Secure read-only connections to banks, brokerages, and card issuers. Credentials never touch the app directly.
Ledger Transaction Store A local-first database of every transaction, labeled and deduplicated. Built so you own the data, not a vendor.
Categorizer Rules & ML Hybrid Starts with rules you set, learns the edge cases over time. Fewer miscategorized Chipotle runs, more accurate trend lines.
Scoreboard Reporting Layer Net worth, cash flow, savings rate, and category deltas — rendered as the report a private CFO would hand you each Sunday.
Why it's built this way

Personal finance data is the most sensitive data you have. The architecture prioritizes local-first storage, read-only integrations, and zero third-party data sale. Separate layers mean you can swap any aggregator without losing your history — your ledger is yours, independent of whoever last made a decent data feed.

Why It Matters

Net worth is the only honest score.

Income is a vanity number. Spending is a confession. Net worth is the truth — it moves whether you feel productive or not. Measure it cleanly and the right decisions get easier: which expense to cut, which account to fund, which risk to actually take.

This one stays private by design. The goal is clarity for the one person it's for.
