IndoLingua — Frequently Asked Questions

Is IndoLingua free?

Yes, the Discovery plan is free forever: 10 lessons and 100 flashcards, no credit card required. The full A1-C2 curriculum is in Pro (€12.99/mo or €99/yr), and the unlimited AI teacher plus all digital books are in Premium (€24.99/mo or €179/yr).

How long does it take to learn Indonesian with IndoLingua?

Indonesian is FSI Category II (about 900 hours to professional fluency for English speakers). With 20-30 minutes of daily practice, most learners reach A2 (basic conversation) in 3-4 months and B1 in 6-9 months.

What do the Pro and Premium plans include?

Pro unlocks all 180 CEFR lessons (A1-C2), every exercise, unlimited flashcards, progress analytics and cross-device sync. Premium adds the unlimited AI conversation teacher, all digital course books, the OCR scanner, the dictionary and voice translation.

Does IndoLingua deliver an official certificate?

IndoLingua issues a personal certificate of progression that tracks the CEFR level you have completed inside the app. It is a motivational record of your own progress, not an officially accredited or government-recognised diploma.

Is there an AI teacher?

Yes. Premium includes an unlimited AI conversation teacher you can chat with to practise speaking and writing Indonesian, with instant corrections. It complements the lessons; it is not a replacement for a human tutor for formal exam coaching.

Can I get a refund?

Pro starts with a 3-day free trial so you can test it before being charged. You can cancel anytime from your account and keep access until the end of the paid period. Refunds are handled by our payment provider Paddle in line with applicable consumer law.
