No bank logins · ever

A record of what you're worth. Kept by you.

WorthOS is a net-worth notebook. Once a month you write down what you have and what you owe — by hand, on your device, and nowhere else. It charts the rest.

Why it's offline
No sync, no servers

Your numbers live in one local file. There is no account to create, no cloud to trust, no breach to read about later.

Written by hand, on purpose

Typing the numbers once a month is the feature. Ten minutes of attention beats a feed you never look at.

Observations, never advice

WorthOS charts what happened and what it implies. It never scolds a down month and never sells you a product.

One notebook · four covers

Click a cover — the whole page follows. In the app it's one tap in Settings.

How a month goes
01
Jot the numbers

Accounts, debts, roughly what came in and went out. Rough is fine — you can correct anything later.

02
Read the entry

One number, one line, and what changed. Milestones get stamped; down months get recorded, not judged.

03
Glance ahead

A two-year sketch with honest uncertainty. Explore a range of outcomes, stress-test a surprise expense — always a projection, never a promise.

What it is not
Not a budgeting app

No transaction feeds, no category police. WorthOS looks at the whole once a month, not every coffee.

Not a robo-advisor

It will never suggest a fund, a card, or a refinance. There is nothing to sell you, so the numbers stay honest.

Not a data business

Your net worth is worth a lot to advertisers. It is worth more to you. That's why there is no server.

In your pocket too
The companion, not the desk

The phone app is for glancing and jotting: this month's number, a quick entry while the statements are open, a goal checked in a queue. The long sits — forecast levers, the year in review — stay on the big screen.

Same file, same skins, moved between devices by you — a local sync over your own network, never a cloud.

Fair questions
What happens if I stop paying?

Nothing. You paid once. The app, your entries, and the export are yours for good — updates included while we're around.

What if WorthOS shuts down?

The app keeps working — it never phoned home to begin with. Your file is documented, and CSV export means nothing is trapped.

Manual entry sounds like work.

It's about ten minutes a month, and that's the point — the one sitting where you actually look. Most people start remembering their numbers by entry three.

Is my data encrypted?

While your notebook is locked, yes — encrypted with a key derived from a passphrase only you know. Once you unlock it for the session, the data is as accessible as any other page's, exactly like any local app. Choose a passphrase you'll remember: at least 12 characters, and there's no way to recover a forgotten one — not even us.

One notebook, no fine print.
