Privacy Policy
Last updated: 2026
This privacy policy explains what information stonegravelcalculator.com (“we”, “us”) collects when you use this website and how it is used.
Calculator inputs
Everything you type into a calculator – dimensions, weights, prices – is processed in your own browser. We do not send, store or see your calculator inputs. Nothing is saved when you close the page.
Information we collect automatically
Like most websites, our server and analytics tools record standard technical information when you visit: your IP address (shortened/anonymised where the tool allows), browser type, device type, the pages you view, the time of your visit and the site that referred you. We use this to understand which calculators are useful, fix errors and keep the site secure.
Cookies
We use cookies for:
- Analytics – to measure visits and page views in aggregate.
- Advertising – this site is supported by advertising. Our advertising partners (such as Google AdSense) may use cookies to show ads based on your previous visits to this and other websites. You can opt out of personalised advertising at Google Ads Settings and learn more at Google’s advertising policies.
You can block or delete cookies in your browser settings. The calculators work without cookies.
If you email us, we keep your message and address for as long as needed to answer you and keep a record of the correspondence. We do not add you to any mailing list.
Third-party links
Pages may link to other websites. We are not responsible for their content or privacy practices.

Depending on where you live (including under the GDPR and UK GDPR for visitors in the EU and UK, and the CCPA for California residents), you may have the right to access, correct or delete personal data we hold about you, or to object to its processing.
