Privacy
This site sets no cookies of its own, has no accounts, and collects nothing you type into the calculator.
The calculator runs entirely in your browser.
Analytics
We use Cloudflare Web Analytics, which is cookieless and does not fingerprint or track individuals across sites.
The contact form
The contact form is hosted by a third party, Formspree. What you type is transmitted to and stored by Formspree and forwarded to the editor by email. Do not put anything confidential into it.
Links out
Following a link to a vendor takes you to their site under their terms. Some links are affiliate links, which tells the vendor the visit came from here — not who you are. See the disclosure page.
What we never do
We do not sell, rent or share contact details and we do not pass your details to vendors as a sales lead. There is no mailing list and no quote form. The calculator sends nothing anywhere, and the method page describes what we collect about vendors, which is only what they publish.
