Your progress

Your progress is stored only in this browser, on this computer. Nothing is sent anywhere. That keeps the course free of accounts and passwords, and it means you decide where the data lives.

How progress works

• Every lesson ends with a Mark as done button. The sidebar shows a tick next to done lessons and a count per section; the bar in the top bar shows the total.
• Reference pages (glossary, cheat sheets, this page) do not count towards the total.
• Checklists such as the learning outcomes are stored separately, also in this browser.
