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.

We use Cloudflare Web Analytics to see how many people visit, which pages they open, and roughly where traffic comes from. It does not use cookies, and it does not attach the numbers you type in the calculator. We use it to know whether the site is being used, not to identify you.

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