You do not need to sign up. Your lesson progress, streak, theme and caught memes are stored only in your own browser (local storage). Clearing your browser data removes them. We cannot see them.

Analytics

• Cloudflare Web Analytics counts visits, pages, countries and page speed without cookies or personal identifiers.
• Google Analytics 4 shows us which lessons and links are used, so we can improve them. It sets cookies. In the UK, EU and Switzerland it only runs after you press Allow in the banner. Elsewhere it runs by default. Advertising features and Google signals are switched off, and data is kept for 14 months.
• We never send what you type in a lab terminal, your quiz answers, or any personal details to analytics.

Opt out

Block analytics with your browser's tracking protection or an extension, or use the Google Analytics opt-out add-on. In regions with the banner, your Decline choice is remembered in local storage. To change it, clear this site's data and choose again.

Third parties

Videos are YouTube embeds, which may set cookies when you play them. Live follower counts come from public pages of our social profiles. The site is delivered by Cloudflare, which processes standard request data (such as IP address) to serve and protect the site.
