What the calculators do with your inputs

Every calculator on this site runs in your browser. When you type a number into a field, that number is used to compute a result on your own device. Nothing you enter into a calculator is sent to our servers or stored by us.

What we do collect

Like most websites, we use standard analytics to understand which pages get used and which don't. We use Google Analytics 4, which collects page views, approximate location at the country or region level, device type, and referral source. This data is aggregated and isn't tied to your name or contact details. You can opt out of Google Analytics with Google's opt-out add-on or by blocking analytics cookies in your browser.

We use cookies for two things: remembering your dark mode preference, and basic analytics. Neither is used to build an advertising profile tied to your identity.

The contact form

If you use the contact form, we collect the name, email, and message you provide. That information is used only to respond to you. It isn't added to a marketing list. Form submissions are delivered to us through Web3Forms, a form delivery service, which processes the message on our behalf.

Advertising

This site currently carries no advertising, and no ad providers collect data here. If advertising is added later, this policy will be updated first to name the providers and explain your choices.

Third-party links

Pages on this site link to external sources, including DSIRE, the National Laboratory of the Rockies (NLR), and NRCan, for the data behind our figures. Those sites have their own privacy practices, which we don't control.

Your choices

You can clear cookies at any time through your browser settings. Doing so will reset your dark mode preference back to your system default and won't affect any calculator's function, since the calculators don't depend on stored data to work.

Changes to this policy

If this policy changes in a meaningful way, we'll update the date at the top of this page.
