Privacy

GPA Peek for Course Explorer (unofficial browser extension) and its lookup website.

Short version: nothing about you is collected, stored or sent anywhere.

The extension

• It runs only on https://courses.illinois.edu/.
• On those pages it reads course codes and instructor names that are already shown, and adds GPA badges next to them. That processing happens entirely inside your browser.
• It does not read or store your identity, NetID, schedule, browsing history, cookies or anything you type.
• It makes no requests to the university's servers and performs no actions on your behalf (no clicking, no registering).
• About once a day it may download an updated copy of the public grade dataset from this project's GitHub Pages site. That request contains no information about you or about the pages you visit. As with any web request, GitHub can see your IP address; see GitHub's privacy statement.
• The only thing it saves on your device is that dataset and the time it was last checked (browser extension storage). Removing the extension removes it.
• It contains no analytics, advertising or tracking code, and uses no remote code: everything it runs ships inside the extension package.

Permissions requested: storage (to keep the downloaded dataset) and access to courses.illinois.edu (to add the badges).

The website

The lookup site is a static page hosted on GitHub Pages. Searches run in your browser against a data file; what you search for is never sent to a server. The site sets no cookies and has no analytics. GitHub, as the host, may log requests for the page itself.

The data

Grade distributions come from University of Illinois public records as compiled in wadefagen/datasets. They are aggregate counts per course section and contain no student information. Sections with 20 or fewer students are not included.
