There are no advertising cookies and no analytics trackers on this site.

Your lesson progress is stored only in your own browser via localStorage. It is not sent to a server. Clearing the site data in your browser removes it.

YouTube videos load only after you press play, and they load from youtube-nocookie.com. From that moment YouTube's own privacy policy applies to the playback.

If you email us or send us a message, we use what you send only to reply to you.
