Privacy Policy

What we collect

EngCalcu does not require an account and does not ask for your name or contact details to use any calculator. Values you enter into a calculator are processed in your own browser and are not sent to us.

Data stored in your browser

The BOQ Builder saves your bill of quantities in your browser's local storage so it is still there when you return. This data stays on your device. You can delete it at any time with the "Clear BOQ" button or by clearing your browser data.

Analytics

We use privacy-friendly website analytics to count visits and see which pages are popular. This data is aggregated and is not used to identify you.

Advertising

We may show advertising to keep the calculators free. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this site and other sites on the internet.

You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of some third-party vendors' use of cookies for personalised advertising at aboutads.info.

Affiliate links

Some pages may contain links to products, courses or software. If you buy through these links we may earn a commission, at no extra cost to you.
