Privacy Policy

This page covers what happens to your information on Catalytic Converter Replacement Cost, from the calculator on the home page to the contact form and the ads that keep the site free. It was last revised on 2026-07-08. Using the site means you accept the practices below.

The calculator itself sends nothing to us

Selecting a converter type, vehicle class, converter count, or typing a ZIP code into the home page tool runs entirely in JavaScript on your own device. None of those choices are transmitted to our servers, logged, or tied to you in any way. Close the tab and the numbers are gone.

What we get if you reach out

Our contact form is handled by a third-party form delivery service, and submitting it sends us your name, email address, and whatever you write, so we can reply. We keep those messages only as long as it takes to answer you and to keep a short record of corrections we have made.

Cookies, ads, and analytics together

Like most sites carrying display advertising, we and our partners, including Google, place cookies to run the site, measure traffic through Google Analytics, and show ads matched to your browsing history across the web. You can turn off ad personalization at Google's Ads Settings page and see the full list of participating vendors at the Digital Advertising Alliance's aboutads.info.

If you are in the EEA, UK, or Switzerland

A consent banner appears on your first visit asking permission before any non-essential advertising or analytics cookie is set. Reject or accept at that point, and change your mind later by clearing cookies in your browser. Wherever you live, you can ask us to show you, correct, or delete the personal data we hold, or to stop selling or sharing it, by writing through the contact page.

Who else sees this data

We do not sell the details you type into our contact form. Outside vendors that help run analytics, advertising, and the form itself see only what their function requires, and only under their own privacy commitments.

Not built for children

This is a repair cost resource meant for adult vehicle owners. We do not knowingly gather information from anyone under 13, and the site is not marketed to that age group.

Updates to this policy

If this policy changes, the revision date at the top will move. Questions about anything here can go through our contact page, and the sourcing behind our cost figures is covered separately on the editorial standards page.
