Privacy
The short version: calculations happen in your browser, and this site does not set cookies or run analytics.
What you type
Every calculator on this site runs entirely in your browser. The numbers you enter are never sent to a server, never stored, and never logged. If you use a calculator with JavaScript disabled you are reading the default example, which is also computed locally at build time.
Server logs
Like any website, the server keeps an ordinary access log: the page requested, the time, the response code and the requesting IP address. That log exists to diagnose faults and detect abuse, is retained briefly, and is not used for profiling, advertising or analytics.
Cookies and third parties
This site currently sets no cookies and loads no third-party scripts, fonts or trackers.
If advertising is added in future, this page will be updated before that happens to name the advertising provider, describe the cookies it sets, and explain how to opt out of personalised advertising. Nothing will be added silently.
