Security

What happens, from a security standpoint, to the numbers you type into a calculator.

Last reviewed: November 2, 2026Reviewed by Michael Steve

Calculations run in your browser

Every calculator on this site runs entirely in your own browser's JavaScript. The price, trade-in, ZIP code and every other value you enter never leaves your device, isn't sent to our servers, and isn't stored anywhere. Close the tab and it's gone.

No accounts, no passwords

There is no sign-up, no login and no account on this site. With nothing to register for, there is no password database or user profile that could be exposed.

HTTPS

The site is served over HTTPS, so the connection between your browser and our host is encrypted.

The contact form

The one place this site does collect anything is the contact form, where a name, email and message you choose to send us are submitted to our form handler. See the privacy policy for what that involves.

Analytics and advertising

We use Google Analytics to see, in aggregate, how the site is used, and the site may show ads through Google AdSense or similar networks. Both can set their own cookies. Full detail, including how to opt out, is in the privacy policy.
