Why MoneyMetric?
Unlike portals that feel like article farms with a calculator attached, MoneyMetric explains every formula, shows amortization tables and local charts, and never sends your financial inputs anywhere.
FAQ
Is it free?
Yes — every tool is free with no signup and no credits.
Is my data uploaded?
No. Tools run locally in your browser; files never leave your device. Check DevTools → Network.
Does it work offline?
After the first visit the app shell is cached, so calculators and generators keep working offline.
Does it work on mobile?
Yes — touch-friendly, one-tap download, adaptive workers for weak devices.
How do you make money?
Clearly-labeled ads, spaced away from buttons. No paywall, no fake download buttons.
