Instant & freeEvery tool runs the moment you type — no accounts, no paywalls, no waiting.

Private by designYour numbers and text are handled in your browser, not sent to our servers.

Works everywhereFast and tidy on phone, tablet and desktop, whenever you need a quick answer.

Privacy, in brief

Convertly doesn't ask you to create an account, and it doesn't store what you convert. Nearly every tool here runs entirely in your browser, so the numbers and text you type never reach a server at all.

No analytics: no Google Analytics, no heatmaps, no session recording. That was a deliberate choice.
Advertising: the site is free because it shows ads through Google AdSense, which may use cookies to serve and measure them.
Your data stays yours: BMI figures, pasted text and generated passwords are processed on your own device and never transmitted.

The full privacy policy names every third-party service the site contacts and explains exactly what each one does. Questions? Email info@firirigs.com.
