Privacy policy

Material Maths is a free calculator website. You do not need an account, and we do not ask for personal details to use any tool on the site.

What we collect

• Calculator inputs. The measurements and prices you type stay in your browser. They are not sent to us or stored on a server.
• Analytics. We may use privacy-respecting analytics to count page views and understand which calculators are useful. This data is aggregated.
• Email. If you email us at hello@materialmaths.co.uk, we keep your message so we can reply.

Advertising

This site is funded by advertising, which may include Google AdSense. Advertising partners may set cookies or use similar technologies to serve and measure ads, including personalised ads where you have consented. Consent is collected through Google's own consent message, and you can change your choices at any time through that message.

Your rights

Under UK GDPR you can ask what personal data we hold about you, ask us to correct or delete it, and object to processing. Email hello@materialmaths.co.uk and we will respond within one month. You can also complain to the Information Commissioner's Office (ico.org.uk).

Changes

We may update this policy as the site develops. The current version always appears on this page.
