Cookies and local storage
The site uses no advertising or analytics cookies. It stores a few small things in your browser so it works properly.
What we store in your browser
Your sign-in token, after you log in, so you stay signed in. Logging out removes it.
The site’s colours and fonts, so pages load without a flash of the wrong style.
Your Windows or Mac choice on lesson pages, so you don’t have to pick it again.
Third parties
Fonts load from Google Fonts. Tool links take you to other websites, which have their own cookie policies. Affiliate links may let the other site know you came from us.
Clearing it
You can clear this data at any time in your browser settings. The course still works; you will just need to sign in again.
