Cookies
This site uses Google Analytics 4, which sets cookies to count visits. We set no advertising cookies ourselves.
What is used
Google Analytics 4 sets first-party cookies (their names start with _ga) to tell one visit from another and to count page views. Calculator use is recorded as a tool name only, never what you type.
What is not used
We do not use advertising or social media tracking cookies on this site. Your calculator entries are not stored in cookies.
How to turn it off
The counter does not run at all if your browser sends Do Not Track or Global Privacy Control. You can also block or delete cookies in your browser settings, or install Google's opt-out browser add-on. The site and calculators still work without cookies.
