Privacy Policy

The short version

This website collects nothing. There are no analytics scripts, no advertising networks, no cookies and no third-party requests of any kind.

Every calculator runs entirely in your browser. The numbers you type are never transmitted anywhere — there is no server to send them to.

What is stored on your device

Nothing is written to local storage or cookies. If you use a calculator, the numbers may appear in the page URL so the result can be bookmarked or shared, but that URL stays in your browser unless you copy it somewhere yourself.

Server logs

The web host that serves these pages keeps standard access logs, which typically include IP address, browser user agent and the page requested. These are used only to keep the site running and are not combined with anything else or used to build a profile.

The mobile apps

The iOS and Android apps are separate products with their own privacy disclosures, shown on their App Store and Google Play listings. Purchases and subscriptions are handled entirely by Apple and Google; this site never sees payment information.
