Privacy Policy

Overview

Material Calculators (“we”, “us”, or “the site”) is a free utility website. We collect as little information as possible. The calculators run entirely in your browser — the measurements you enter never leave your device and are not stored on our servers.

Information we do not collect

• We do not require an account and do not collect your name, email, or password.
• We do not store the measurements or calculation inputs you enter into any calculator.
• We do not sell or rent personal information to third parties.

Information collected automatically

Like most websites, our hosting provider and analytics tools (when enabled) may automatically record the following non-personal technical data:

• IP address (used for aggregate, anonymized traffic statistics and abuse prevention).
• Browser type, operating system, and screen size.
• The pages you visit and the referring URL.
• Approximate region derived from IP address (not precise location).

This data is used in aggregate to understand how the site is used and to improve it. It is not used to identify you personally.

Cookies

We use minimal cookies. Necessary cookies (if any) support basic site function. If we enable analytics (such as Google Analytics 4) or advertising (such as Google AdSense), those vendors may set their own cookies. You can control or block cookies through your browser settings; doing so will not prevent you from using the calculators.

Analytics

We may use Google Analytics 4 to understand aggregate traffic patterns. Google Analytics collects anonymized usage data using cookies. You can review Google’s privacy practices and opt out using the Google Analytics Opt-out Browser Add-on.

Advertising

If approved, we may display ads through Google AdSense. AdSense and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings. Third-party vendors and ad networks are governed by their own privacy policies.

Children’s privacy

The site is not directed to children under 13 and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it.

External links

Our pages may link to third-party websites. We are not responsible for the privacy practices or content of those sites. Review their privacy policies before submitting any information.

Changes to this policy

We may update this Privacy Policy from time to time. Changes take effect when posted on this page with an updated revision date.
