Cookies and audience measurement

We measure traffic to learn where the site helps and where we lose you along the way. Nothing non-essential is switched on without your agreement, and refusing is as easy as accepting.

What we measure, and what we do not

Page views and steps completed: goal entered, path preview shown, account created, lesson opened or finished.
Device type (desktop, mobile, tablet) and the site you came from.
Never your IP address, never the text you type (goal, code, questions to the tutor), never your name or e-mail.
Measurement data is kept for 13 months at most, then deleted.
