Privacy policy

This page explains what data roofingmaterialcalc.com collects and how it is used. The calculators themselves run entirely in your browser — the measurements you enter are not sent to or stored on our servers. The areas below cover the third-party services the site uses.

Analytics

We use Google Analytics (GA4) to understand how visitors use the site in aggregate — which pages are visited, broad location and device type, and similar usage patterns. Google sets cookies and may process this data on our behalf; it helps us improve the tools and content. You can opt out with the Google Analytics opt-out browser add-on, or by blocking cookies in your browser.

Advertising

This site is supported by advertising. We use Google AdSense and Adsterra to display ads. These networks and their partners may use cookies or similar technologies to show ads, and in some cases to personalise them based on your prior visits to this and other websites. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this or other sites. You can learn about and manage Google's ad personalisation at Google Ads Settings, and opt out of personalised advertising from participating vendors at aboutads.info.

Affiliate links

Some outbound links on this site are affiliate links. If you click one and make a purchase, we may earn a commission at no extra cost to you. This never changes the numbers our calculators produce, and we do not let affiliate relationships influence the methodology or the recommendations in our guides. We don't publish product prices, and our estimates are based on sourced material constants, not on what any retailer pays.

Cookies & consent

The services above set cookies. Where required (for example under GDPR in the EU/UK), a consent prompt governs whether non-essential cookies for analytics and personalised advertising are set. You can change or withdraw consent at any time through your browser's cookie controls.

Your choices

You can block or delete cookies in your browser settings, use the Google Analytics opt-out add-on, and manage ad personalisation through the links above. Blocking cookies will not stop the calculators from working, since they run locally in your browser.
