Your numbers stay on your device.

True Burn has no accounts and no database. Income, savings, and expenses you type are not sent to our server. They live in this browser tab. If you copy a scenario link, those figures are in the URL you choose to share.

The mid-market exchange rate is fetched from a public third-party API so you do not have to look it up. We do not attach your expense numbers to that request — only the currency pair.

This page will be updated if we later add email, analytics, or affiliate tracking.
