Frequently asked questions

Are these money tools really free?

Yes. Every tool here is free with no watermark, no limits and no sign-up.

Is my financial data uploaded anywhere?

No. The tools run inside your browser, so your figures stay on your device and are never sent to a server. Use each tool's backup option to keep a copy.

Can I move my data to another device?

Yes. The bookkeeping, money manager, net worth and debt tools let you export a JSON backup and import it on another device to restore everything.
