What we collect

If you join the waitlist or ask for the sample report, we store the email address you give us, what you said you measure (optional), and the time and page of the request.

The free calculators run in your browser. The numbers you paste are not sent to us.

How we use it

We use your email to send the report you asked for and, once, to tell you when early access opens. We do not sell it and we do not use it for advertising.

Addresses we check

When you submit an address we check that it is well formed and can receive mail. Addresses from throwaway services are refused.

Cookies and storage

The site sets no cookies. Your light or dark choice is kept in your browser's local storage on your own device.

Service providers

The site is served through a content delivery network that logs requests for security and aggregate statistics, and email is sent through a mail delivery provider.

Your choices

Ask us to delete your address at any time by replying to any email we send you, and we will remove it.
