Questions & answers
Everything you need to know
What does my subscription include?
One subscription unlocks every level in your language category — A1 through C1 — including all units, lessons, quizzes and review lessons. You can choose a monthly or yearly plan.
Which devices can I learn on?
Kustau is designed mobile-first and works on phones, tablets and desktop. Your progress syncs across every device, so you can switch seamlessly.
How do lessons and units work?
Every lesson is built around the same four pillars: vocabulary, grammar & function, reading & listening, and sounds & pronunciation. A unit then groups a series of lessons (typically four) and always finishes with a Review Lesson — which includes a video-based quiz on the previous lessons in the unit.
Am I eligible for a certificate?
To receive the final certificate of completion, you'll need to pass every Review Lesson in your level. Review Lessons can be retaken as many times as you need.
How is my progress tracked?
Your dashboard shows clear progress bars for every level, unit and lesson, plus your recently completed lessons and upcoming reviews — so you always know your next step.
How do payments work?
Subscriptions are billed securely through WooCommerce Subscriptions, with Flutterwave supporting recurring payments — including Mobile Money options such as Orange Money and MTN MoMo.
