What we collect
Purchases and free downloads. Checkout and delivery are handled by Payhip. When you buy or request a free download, Payhip collects your name, email and payment details and shares your name and email with us so we can deliver the product and support you. We never see or store your card number. See Payhip's privacy policy for how they handle your data.
Calculator. The roofing calculator runs entirely in your browser. Nothing you type into it is sent to us or stored.
Analytics. We may use Google Analytics to understand which pages are useful, which collects standard usage data such as pages visited, device type and approximate location, using cookies. You can block this with your browser settings or an ad blocker.
How we use it
To deliver your purchase, answer support requests, and, if you requested the free cheat sheet or bought the pack, send occasional emails about pricing tips and our products. Every email has an unsubscribe link. We do not sell your information.
