What we collect
Nothing directly. There are no forms, no accounts, no newsletter and no comments. The calculators run in your browser, and the numbers you type never leave your device.
Hosting and statistics
The site is hosted on Cloudflare. Like any host, Cloudflare processes basic request data such as IP address and browser type to deliver pages and block abuse. We may use Cloudflare Web Analytics, which counts visits without cookies and without tracking you across sites.
Fonts
Fonts are served from this site, so your browser doesn't contact any font service.
Changes
If this changes, we'll update this page and its date.
