Cookie policy
Short version
This marketing site doesn't currently use tracking or advertising cookies. We load fonts from Google Fonts, which involves a request to Google's servers but doesn't set a tracking cookie on this site.
The course app
The course itself uses your browser's local storage (not a cookie, technically) to save your progress on your own device, and — only if you choose to set a PIN — a small amount of encrypted data to let you continue on another device. See our security page for detail.
If this changes
If we ever add analytics (e.g. to see which pages are useful) or advertising, this page will be updated first, and we'll ask for consent where the law requires it.
