Your loan data

All calculations run locally in your browser. The amounts, rates, and terms you enter are never transmitted to our servers or any third party. Shareable links encode inputs in the URL only when you explicitly click Share.

Analytics & advertising

We use Google Analytics 4 to understand aggregate site usage, and display advertising to keep the tools free. Ad partners may use cookies subject to your consent choices, which you can change at any time via the consent banner. We do not run lender advertising or lead generation of any kind.

Local storage

Your theme preference (light/dark) is stored in your browser's localStorage and nowhere else.
