Your learning.
Your data.

Privacy information for this early version of Linux Exercises.

What is stored

Guest progress, lab command transcripts and preferences stay in your browser. You can export or reset guest progress from the dashboard. If you create an account, the application database stores your name, email, a salted password hash, a hashed recovery key, session identifiers and completed lesson records. Email ownership is not yet verified.

Practice commands

Commands run inside a limited simulation. When checking an exercise, its command transcript is sent to the server and replayed for validation. The application does not store raw transcripts in its database. Browser progress may contain practice commands; avoid entering sensitive information.

Payments

PayFast handles payment details on its hosted checkout. This application stores order references, subscription tokens, payment amounts and access dates. Card details are not collected by this application. Billing records are retained separately from account data for reconciliation.

Cookies and tracking

A first-party HttpOnly session cookie keeps signed-in learners authenticated for up to 30 days. Guest progress uses local storage. No advertising trackers or third-party analytics are installed.

Your controls

Account settings allow data export, password changes and account deletion. Cancel recurring billing before deleting an account. Account data is kept until you delete the account. Payment records are retained separately for reconciliation. Browser data is separate and can be cleared on the dashboard or in browser settings.

Operator and questions
