Privacy Policy

Last updated: June 2, 2026

This Privacy Policy explains how BuildCalc (“we”, “us”, or “our”) handles information when you use buildcalc.xyz (the “Service”) — a free collection of building-material calculators.

We have written this policy to be plain and honest. BuildCalc is a static, front-end website: our calculators run entirely in your browser, and we do not ask you to create an account or submit the numbers you enter.

Information we collect

Information you enter into calculators. Measurements, prices, and other values you type into a calculator are processed locally in your browser to produce an estimate. These values are not transmitted to or stored by us.

Usage data collected automatically. Like most websites, our hosting provider and analytics/advertising partners may automatically collect standard technical information when you visit, such as your IP address, browser type, device type, pages viewed, referring page, and approximate (country/region-level) location. This is used to operate, secure, and improve the Service.

Cookies and local storage. We and our third-party partners use cookies, local storage, and similar technologies for purposes such as remembering your unit preference (imperial/metric) and theme, measuring traffic, and serving advertising. You can control or delete cookies through your browser settings; doing so may affect some conveniences (e.g. remembered preferences).

Advertising and third-party services

We may display advertising and use analytics provided by third parties, including Google AdSense and Google Analytics. These partners may use cookies and device identifiers to measure performance and to show ads that are more relevant to you.

  • Google may use advertising cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising via Google Ads Settings and learn more at how Google uses information from sites that use its services.
  • Where required by law (for example, for visitors in the UK and EEA), we use a Google-certified consent management platform with Consent Mode v2 to request your consent before non-essential cookies (including advertising and analytics cookies) are set. You can change your choice at any time through the consent banner.

We do not sell your personal information.

How we use information

We use the limited information described above to: operate and maintain the Service; understand how the calculators are used so we can improve them; keep the site secure; and fund the free service through advertising.

Your rights

Depending on where you live (for example, under the GDPR in the EEA/UK or the CCPA in California), you may have the right to access, correct, or delete personal data, to object to or restrict certain processing, and to withdraw consent. Because we do not maintain user accounts, most requests will relate to cookies and data held by our advertising/analytics partners, which you can also manage directly through the links above. To make a request to us, contact us using the details below.

Children’s privacy

The Service is not directed to children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from them.

Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above. Significant changes will be reflected on this page.
