Privacy Policy

Overview

BuildCalc ("we," "our," or "the site") is a free collection of construction material calculators. This Privacy Policy explains what information is and is not collected when you use the site, how cookies are used, and the choices you have. By using BuildCalc, you agree to the practices described here.

This policy was last updated in January 2026. If we make material changes, we will update this page.

Information We Do Not Collect

BuildCalc runs entirely in your browser. Every calculation you perform — dimensions, quantities, costs, and any other numbers you enter — is processed locally on your device. Your calculator inputs are never transmitted to, stored on, or logged by our servers.

We do not require an account, and we do not ask for your name, email address, phone number, or any other personal information in order to use the calculators. If you choose to email us, we will have the contact details you include in that message and will use them only to respond to you.

Cookies

Cookies are small text files placed on your device by websites. BuildCalc itself does not set first-party cookies for tracking or identification purposes. However, third-party services used on the site — described below — may set or read cookies on your device subject to their own privacy policies.

You can control or delete cookies at any time through your browser settings. Disabling cookies will not affect the core functionality of the calculators.

Third-Party Advertising (Google AdSense)

We use Google AdSense to display advertisements on BuildCalc. Google and its advertising partners use cookies — including the DoubleClick cookie — to serve ads based on your prior visits to this site and other sites on the internet. This is known as personalized or interest-based advertising.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet. BuildCalc does not control and is not responsible for the data practices of these third-party vendors; their use of information is governed by their own privacy policies.

Your Choices: Opting Out of Personalized Ads

You may opt out of personalized advertising by visiting Google's Ads Settings at adssettings.google.com. You can also opt out of many third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info/choices.

Opting out will not stop ads from appearing; it means the ads you see will be generic rather than tailored to your browsing history.

Analytics

We use Cloudflare Web Analytics to understand aggregate traffic patterns — such as which pages are visited and how the site performs. Cloudflare Web Analytics is privacy-focused: it does not use cookies, does not track individual users across sites, and does not collect personal identifiers. The data we see is aggregated and anonymous.
