The short version
The calculators run in your browser, and what you type into them isn’t sent to us. There are no accounts to sign up for and no ads.
The calculators
Calculations run in your browser. What you type into a calculator isn’t sent to us. If you use “Copy link to these numbers”, your inputs are in the link itself, so anyone you share it with can see them.
What your browser remembers
We use your browser’s local storage, not cookies, to remember four conveniences on this device: your light or dark choice, US or metric units, the state you picked for prices, and any prices you typed into a cost estimate. Clear your browser’s site data to remove them.
Hosting
The site is hosted by Cloudflare. Like any web host, Cloudflare handles basic technical information, such as your IP address, browser type and the pages you request, to deliver the site and protect it from abuse. See Cloudflare’s privacy policy.
Ads, affiliate links and email
There are no ads on this site yet. Before any are switched on, this page will name the ad company, the cookies it uses and how to opt out.
There are no affiliate links yet. If we add them, they’ll be marked on the page, and following one may let the store know you came from us.
There’s no email signup yet. If we add one, this page will name the email provider first.
Children
This site isn’t directed at children under 13, and we don’t knowingly collect personal information from them.
Changes
If what we collect changes, we’ll update this page and the date at the top.
