Analytics
Since August 2026 this site uses Vercel Web Analytics to count visits. It is cookieless and does not track you across other websites.
What it records for each page view: the page URL, the referring site, your country, and your device type, operating system, and browser. To count returning visitors within a single day it derives a hash from your IP address and browser user agent; the raw IP address is not stored, and the hash is discarded every 24 hours, so visitors cannot be followed from one day to the next.
What it does not record: your name, email, IP address, precise location, or anything you enter into the calculators. We use this only to see which tools get used and which do not.
Ads
There are no ads on this site today. If that changes, this page will be updated to say so.
