Analytics and server logs
Like most websites, our hosting provider may record standard technical information in server logs — such as your IP address, browser type and the pages you request — for security and to keep the site running. We do not use these logs to identify you, and we do not sell data.
Your choices
You can block or delete cookies through your browser settings; the calculators keep working, because they do not depend on cookies. You can also use the Google Ads Settings link above to control personalised advertising.
