The arrangement you never agreed to

Your entire financial life is sitting on someone else’s servers.

Every transaction. Every balance. Every habit it reveals about you — held by a company you’ll never meet, secured by a promise you can’t verify.

It’s read to sell you things. It’s one breach away from strangers. And you agreed to all of it the day you clicked “connect your bank.”

Aurum was built for people done making that trade.

How the privacy actually works

Not a policy. Cryptography.

A privacy policy is a promise someone can break. This is architecture that can’t. Here is exactly what happens to a document the moment you drop it in — and exactly what never happens.

Four layers of encryption — every one of them on your Mac.

The AI — local, by design

The analysis runs on AI models on your Mac, through Ollama, accelerated by Apple’s Metal GPU. The model reads your data on your hardware and answers right in the app. Aurum only ever talks to localhost — confirmed in code. There is no API call. There is no “us” in the loop.

No Plaid. No telemetry. No account. The only thing that ever leaves your Mac is a single license check on first launch — your key, never your data, exactly once.

Why trust an app you’ve never heard of

Don’t trust us. Verify us.

Trust is the wrong thing to ask for. A privacy promise from a stranger is worth nothing — it’s exactly what a data grab would say too. So we don’t ask you to believe us. We built Aurum so you can confirm, with your own tools, that your financial data never leaves your Mac.

  1. Watch the network yourself.

    Install a network monitor — Little Snitch, or the free, open-source LuLu. Drop in a statement. Run a full analysis. Watch every outbound connection your Mac makes. You will see Aurum send nothing — because there is nothing to send. The analysis happens entirely on your machine. A data grab can’t survive being watched; that’s why we invite it.

  2. Apple verifies the app, not just us.

    Aurum is signed and notarized through the Apple Developer Program under a real, identifiable developer. macOS itself checks that the app you downloaded is exactly what we shipped — unmodified, untampered. That’s a third party vouching for the binary, independent of anything we claim.

  3. Activate once, then go dark.

    Aurum checks your license a single time, on first launch — your key, never your data. After that it never needs the network again. Run it on a plane, in airplane mode, forever. The one connection it ever makes is the one we’re telling you about right here.

We can’t misuse data we never receive. That isn’t a policy. It’s the architecture.

How it works

From statement to answer, in three steps.

No bank login, no setup wizard, no account. Just your statements and your Mac.

  1. Drag in your statements.

    Drop your bank and card statements — PDFs or CSVs — straight into Aurum. No linking accounts, no handing over credentials. The moment they land, they’re encrypted on your machine.

  2. Local AI reads and organizes.

    AI models running on your Mac, through Ollama, read every transaction — categorizing, finding subscriptions, building the picture. The work happens on your hardware, accelerated by Apple Silicon. Nothing is sent anywhere.

  3. Ask anything about your money.

    Ask in plain language: what you’re spending, what you can afford, where the money’s going, which subscriptions to cut. You get an answer in seconds — and the whole conversation stays on your Mac.

Setup is a drag-and-drop. The privacy is the architecture.

Founding price for the first release. The price rises to $249 after the founding period.

A cloud finance app at $100 a year costs more than Aurum before its second year is out — and keeps charging every year after. Aurum costs you nothing again.
