The calculator

The calculator runs entirely in your browser. The details you enter about your household are not sent to us or stored on our servers. Your answers and the items you tick are saved in your browser’s local storage so your list is still there when you come back. You can remove them at any time by clearing this site’s data in your browser.

Analytics

We use Google Analytics 4 to understand how many people use the site and which pages are helpful. It sets cookies and collects information such as the pages you visit, your approximate location and your device type. We do not send the details you enter into the calculator to Google Analytics – only coarse information such as the number of days chosen.

You can opt out of Google Analytics with Google’s opt-out browser add-on.

Affiliate links

When you click an affiliate link, the retailer (for example Amazon) may set its own cookies to record that you came from this site. Their privacy policy applies once you are on their site.
