Privacy Policy
Last updated: July 18, 2026. The short version: this site has no accounts, collects no personal information through the calculator, and uses analytics to understand aggregate site use.
Calculator inputs
Everything you type into the calculator is processed in your browser. Your inputs appear in the page address so you can bookmark or share a result, but they are not stored by us or tied to your identity.
Analytics
We use Google Analytics 4 to measure site traffic and engagement, such as page views, referral sources, device type, and interactions with site content. Google Analytics may use cookies or similar technologies as described in Google's privacy documentation. We also use Cloudflare Web Analytics for aggregate, cookieless traffic measurement.
Hosting
The site is served by Cloudflare. Like any web host, Cloudflare processes technical request data (such as IP addresses) to deliver pages and protect against abuse. See Cloudflare's own privacy documentation for details.
Advertising
The site currently shows no ads. If we introduce advertising (for example Google AdSense), third-party vendors including Google may use cookies or similar technologies to serve ads based on your visits to this and other websites. You can opt out of personalized advertising in Google Ads Settings, and visitors in regions that require consent will be shown a consent prompt before any advertising cookies are set. This policy will be updated when advertising goes live.
If you email us, we use your address only to reply. We do not run newsletters, share addresses, or send marketing.
