Privacy

Short version: we don't collect personal information, there are no accounts, and the prices, fees and costs you type never leave your browser.

What you type into calculators

Calculations run entirely in your browser. So you don't have to retype them, the numbers you change on each calculator are saved in your browser's local storage on this device only. They are never sent to us or anyone else, and we can't see them. To remove them, use "Reset all to defaults" (and set your sale fields back), or clear this site's data in your browser settings. Private or incognito windows discard them when closed.

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.
