Privacy Policy

The calculators run entirely in your browser. The numbers you type are never sent to us or stored on a server.

We collect standard aggregate analytics: pages viewed, referring site, approximate region, device type and browser. This is used to decide which calculators and guides to build next.

We use cookies for analytics and for affiliate attribution. Amazon sets its own cookies when you follow a product link, governed by Amazon's privacy notice rather than ours.

We do not sell personal information, and we do not run an email list unless you explicitly join one.

You can block or clear cookies in your browser at any time; the calculators keep working. To ask what data we hold about you, or to request deletion, email hello@smartinsulationcalculator.com.

This site is intended for adults and is not directed at children under 13.
