Privacy & Data Practices

We keep your data off the table.

This portal is built to run locally in your browser. We do not collect, sell, or share personal information. Below is a clear, plain-language overview of what happens (and doesn't) when you use this site.

What we do store

Theme preference (light/dark) saved in localStorage.
Dismissal of the privacy notice saved in localStorage so you don't see it again right away.
Course navigation state stored in sessionStorage for your current session only.
Local lesson progress and lab challenge completion saved in localStorage so you can continue where you left off.

What we don't do

No analytics, ads, tracking pixels, or cookies for profiling.
No backend collection of form entries, uploads, or browsing history.
No sale or sharing of data with third parties—there is no third-party data to share.

Where your data lives

Everything listed above is stored in your browser. Clearing your browser storage (cookies/site data) will remove it. If you're on a shared or lab machine, consider clearing storage after your session.

Have questions?

If you need a deeper rundown of data handling for a class, ask your instructor. This site is intentionally simple so you can focus on learning without being tracked.
