What stays free
Every lesson, language, badge and certificate, and all your progress, stay free on the Free plan, which never expires.
What paid plans add
Plus and Pro remove ads for you and add extras, and a parent's or teacher's Pro plan also removes ads for the children or students it covers. You decide if and when to upgrade, and you can cancel any time: when a paid plan ends you move back to Free and keep all your progress. See plans and pricing.
Schools
Schools can stay on a Free plan or choose a paid plan, paid by card through PayPal, or by invoice. See plans and pricing.
