Privacy Policy

Last updated: 2026-05-26

This Privacy Policy explains how CalcMaterials ("we", "us") collects, uses, and protects information when you use our material calculators at calcmaterials.com. We aim to collect as little personal data as possible — the calculators run entirely in your browser and we do not require you to create an account.

Information we collect

We do not ask you to sign up or submit personal information to use the calculators. The measurements you enter are processed in your browser and are not sent to or stored on our servers. We may collect standard, non-identifying analytics data such as pages visited, approximate location (country/region), device type, and referring site, to understand how the site is used and improve it.

Cookies and advertising

We use cookies and similar technologies to run the site and to serve advertising. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and 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.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info/choices or youronlinechoices.eu (EU).

Affiliate links

Some links on this site (clearly marked as affiliate or "Shop" links) are affiliate links. If you click one and make a purchase, we may earn a commission at no additional cost to you. These links may set cookies from the retailer or affiliate network to attribute the referral. See our Disclaimer for details.

Your rights (GDPR / CCPA)

If you are in the European Economic Area, the UK, or California, you have rights over your personal data, including the right to access, correct, or delete it, and to object to or restrict certain processing. Because we do not collect identifying personal data through the calculators, most requests relate to advertising and analytics cookies, which you can control through the opt-out links above or your browser settings. To make a request, contact us using the details on our Contact page.

Consent

For visitors in regions that require it (such as the EEA and UK), we request consent for non-essential cookies, including advertising cookies, before they are set. You can withdraw consent at any time through your browser settings or the opt-out links above.

Children's privacy

This site is not directed at children under 13 (or the equivalent minimum age in your country) and we do not knowingly collect their personal data.

Changes to this policy

We may update this Privacy Policy from time to time. The "last updated" date above reflects the most recent revision.
