Where paid plans work
You can start a paid Plus or Pro plan in most countries. Payments run through PayPal, which screens every transaction against international sanctions rules in real time. In a small number of sanctioned countries PayPal cannot process payments, so paid plans are not offered there.
If paying is not available
If your country is one of the excluded ones, the checkout shows a clear message instead of a payment page, and nothing is charged. This affects only paid plans — it never limits free use of the platform.
Everything stays free
Every lesson, in every language, is free for everyone, everywhere. A paid plan only adds optional extras. See whether the platform is free or paid and how plan changes work.
