Privacy

This page describes how MaterialMath handles your information. It is written in plain language because a privacy policy nobody can read is not a privacy policy.

What we collect

Nothing you type into a calculator is sent to us. The calculations run entirely in your browser, and the figures you enter never leave your device. When you share a calculation link, the values travel inside the URL you copied — we do not receive or store it.

We do not ask you to create an account, and we do not collect names or email addresses except when you choose to email us.

Analytics

We intend to use privacy-respecting analytics to understand which calculators are used and where pages fail people. This measures pages, not individuals. No analytics script is running on the site at the time of writing; this section is here so the policy is complete before one is added.

Cookies and advertising

The site currently sets no cookies. MaterialMath is free and will be supported by display advertising. When advertising is introduced, the ad provider may set cookies or similar identifiers to serve and measure ads, and where the law requires consent you will be asked before any such cookie is set. This page will be updated with the provider and its own policy at that point.

Your choices

You can block cookies and scripts in your browser and every calculator on this site will continue to work, because the calculations do not depend on them.
