No ads on Plus and Pro plans
Every lesson stays free on the Free plan. Plus and Pro are ad-free for the account holder. A parent's or teacher's Pro plan, and a school's paid plan, also make the learners they cover ad-free. See plans and pricing.
No data selling
We do not make money by selling your information. We never share your email, progress, or account details with data brokers or advertisers.
