Privacy

Every calculator on this site runs in your browser. Your inputs are never sent to our servers and never leave your device — except when you press the "Share" button, which copies a link (with your inputs in the URL) to your clipboard.

We use Google Analytics 4 to understand which pages are visited and how calculators are used. All hits are sent with IP anonymization enabled — your IP address is never stored in full. Google Analytics sets a first-party cookie (_ga) that expires after two years. We do not run ads, we do not sell data, and we do not share data with any third party beyond Google's standard analytics processing. You can block analytics with any standard content blocker; the calculators work perfectly with it disabled.
