Privacy

Short version: we don't collect personal information, there are no accounts, and your ZIP code never leaves your browser.

What you type into calculators

Calculations run in your browser. If you choose a state, enter a ZIP code or type your own prices, those are saved in your browser's local storage on your device so they are there next time. They are not sent to us or anyone else. The ZIP-to-state match uses a table that is part of the page itself. You can clear them any time by clearing this site's data in your browser settings.

Cookies, analytics and ads

We don't set cookies and don't currently run analytics, advertising or affiliate tracking. If that changes, we will update this page and our disclosure page before it goes live.

Hosting

The site is hosted on Cloudflare Pages. Like any web host, Cloudflare processes standard request information (such as IP address and browser type) to deliver and protect the site, under Cloudflare's privacy policy.

Children

The site is not directed at children under 13 and does not knowingly collect their information.
