Privacy

Your data stays
on your device.

Your records live on your device, not on our server. There is no sign-up. Only when you ask the smart helper, a short summary of totals is sent to get the answer — never notes or account numbers. Export a backup in settings — the file stays with you.

FAQ

Questions,
answered.

Is it free?

Yes. Wallets, budgets, plans, the portfolio and stats are free. Pro comes later, and there is no price yet.

Where is my data?

On this device, in IndexedDB and browser storage. It is not sent to our server. A file copy goes only where you choose to save it; we never see that file. Exchange rates come from a public source; only currency codes are sent, never amounts or account names.

How do I move it to another phone?

Export a backup in settings and import it on the new phone.

Which currencies?

Currencies from around the world. Live exchange rates are not in yet — you enter the amounts.

Is it on the App Store or Google Play?

Not yet. It runs in the browser. The stores come later.

Does it work offline?

Yes, once the page has loaded.

Do you give investment advice?

No. The portfolio is only your own record.
