Privacy Policy

This site is built so there's very little to have a policy about. Here's the whole picture.

What the site collects

Nothing. Every calculation runs in your browser using the page's own code. The numbers, grades and course names you type are never sent to a server, and there are no accounts, sign-ups or forms that submit anywhere.

Local storage

One preference is saved in your browser's localStorage: your light-or-dark theme choice, if you use the toggle. It stays on your device, and clearing your browser data removes it. Nothing you type into the calculators is stored anywhere, not even locally.

Cookies and analytics

The site's own code sets no cookies. The one external service the pages talk to is Google Analytics, described below; beyond that there are no external requests: no fonts, no ad networks, no other embedded third-party code.

Analytics

The site uses Google Analytics to understand aggregate visitor traffic, such as which calculators are visited and how often. Google Analytics sets cookies and processes usage data according to Google's own privacy policy. What you type into the calculators is not part of that measurement, and the site itself does not collect names, emails or accounts.

Server logs

Like almost every website, the hosting provider that serves these pages may keep standard server logs (IP address, page requested, time). Those logs belong to the host's infrastructure and are not used by this site to identify anyone.

If ads ever appear

Should the site ever carry advertising, the ad provider would come with its own privacy policy, and this page would be updated to say so before that happens.
