Privacy Policy
Plain language. No legalese.
Last updated: March 2026
The short version
LearnSpack.com does not track you, does not sell your data, and does not show personalised ads. We store a small amount of data in your own browser so the terminal remembers your session. That's it.
What we store — and where
| What | Where | How long |
|---|---|---|
| Terminal state (installed packages, CWD, history) | sessionStorage — your browser only |
Until you close the tab |
| Lesson progress | localStorage — your browser only |
Until you clear browser data |
| Login session (if you create an account) | Cookie — your browser + our server |
30 days or until you log out |
| OAuth tokens (GitHub / Google login flow) | Cookie — temporary |
10 minutes, then deleted |
We do not use analytics, advertising cookies, or third-party tracking of any kind. No Google Analytics, no Facebook Pixel, no fingerprinting.
Account data (optional)
If you create an account we store your email address and, if you use OAuth, your provider username. We use this only to identify your session and save your lesson progress server-side.
We do not share this with anyone. You can ask us to delete your account and all associated data at any time by emailing contact@learnspack.com.
Server logs
Our hosting provider (Loopia) keeps standard web server access logs — IP address, timestamp, requested URL. These are used for security and diagnosing errors. We do not analyse them for marketing purposes, and they are retained according to Loopia's standard retention policy (typically 90 days).
External requests
The terminal fetches live package counts from spack.io when you load the trainer. This is a single anonymous request — no personal data is sent. If it fails the terminal works offline.
Your rights (GDPR)
If you are in the EU or EEA you have the right to access, correct, or delete any personal data we hold about you. Since almost everything is stored in your own browser, you can delete it yourself at any time by clearing your browser's site data for learnspack.com.
For anything account-related, email contact@learnspack.com.
This policy may be updated occasionally. Changes will be reflected in the "last updated" date above. LearnSpack.com is an unofficial community resource and is not affiliated with LLNL or the Spack project.
