This page explains which cookies Useful Tools HQ uses and how you can control them. The short version: analytics cookies are only set if you click Accept, and you can change your mind at any time.

What our calculators do with your numbers
Nothing. The calculators run entirely in your browser. The numbers you type are never stored in cookies or sent to us or Google.
Changing your choice
You can accept or reject analytics cookies at any time. If you withdraw consent, we stop Google Analytics and delete its cookies from this site.
You can also block or delete cookies in your browser settings. Google offers a browser add-on to opt out of Google Analytics on all sites.
