Who We Are

CalcTools.uk is a free construction calculator website at www.calctools.uk.

What Data We Collect

Calculator inputs: All calculations run entirely in your browser. We do not collect, store or transmit any of your calculator inputs or results.

Analytics: We use Google Analytics (GA4) to understand how visitors use our site (pages visited, time on site, device type, and which calculator features people use). This only runs if you accept analytics cookies, see Cookies below.

Advertising: We use Google AdSense to display ads. If you accept advertising cookies, Google may personalise ads based on your prior visits to this or other websites. If you reject them, you'll still see ads, but they won't be personalised to you.

Cookies and Consent

Your cookie choices for this site are managed by Google's Funding Choices, a certified consent management platform. It shows a consent message to visitors in the UK and EEA and records your choice. Until you make a choice, and if you decline non-essential cookies, Google Analytics and Google AdSense run in a restricted mode with no analytics or advertising cookies set, only aggregated, non-cookie-based measurement Google provides for this purpose.

The categories are:

  • Essential: Theme preference (light/dark mode), stored in your browser's localStorage, not a cookie
  • Analytics: Google Analytics cookies to measure site usage, set only after you consent
  • Advertising: Google AdSense cookies for personalised ads, set only after you consent

You can change your choice at any time using the "Cookie settings" link in the footer of every page, which reopens Google's consent message. You can also control cookies through your browser settings. If Google's consent message fails to load (for example, if it's blocked by an ad blocker), a simpler fallback banner appears instead so you can still accept or decline non-essential cookies.

Third-Party Services

Your Rights

Under UK GDPR, you have the right to access, correct, or delete any personal data we hold about you. Since we don't collect personal data through our calculators, this primarily relates to analytics data.
