Privacy Policy
Last updated: 22 August 2026
This Privacy Policy explains what happens when you use BuildGrid. We've tried to keep it short, because we collect very little.
1. Calculator data stays on your device
The numbers you enter into our calculators (measurements, prices, quantities, etc.) are processed entirely in your browser using JavaScript. Nothing you type into a calculator field is sent to, or stored on, our servers.
2. Information we may collect automatically
Like most websites, our hosting and analytics providers may automatically log standard technical information when you visit, such as:
- Your approximate location (derived from IP address, not GPS)
- Browser type and device type
- Pages visited and time spent on the site
- Referring website, where applicable
We use this information in aggregate to understand how the site is used and to fix problems - never to identify you personally.
3. Cookies
We may use essential cookies to make the site function correctly, and analytics cookies to understand traffic patterns. You can disable cookies in your browser settings at any time; the calculators will still work without them.
4. Advertising
If BuildGrid displays advertising in future, ad partners may use cookies or similar technologies to serve relevant ads. Any such partner will operate under its own privacy policy, and we'll update this page to name them if that changes.
5. Contact form
If you use our contact form or email us directly, we'll only use the details you provide (name, email address, message) to reply to your enquiry. We don't add you to a mailing list without your consent.
6. Third-party links
Our site may link to other websites, including suppliers or reference material. We aren't responsible for the privacy practices of those third-party sites - please check their own policies.
7. Your rights
You can ask us what information (if any) we hold about you, and request that it be corrected or deleted, by contacting us via the Contact page.
8. Changes to this policy
We may update this policy from time to time. Any changes will be posted on this page with an updated "last updated" date.
9. Contact us
Questions about this policy can be sent to [email protected] or via our Contact page.
