Pricing
Updated September 17, 2026
HSK 1 and 2 are free, with every feature, for good. Studying HSK 3 and 4 is a single payment of US$29. It is not a subscription, and nothing renews.
| Free | HSK 3–4 Unlock, US$29 once | |
|---|---|---|
| Words you can study | HSK 1 and 2: 1,244 words | All 3,000, adding HSK 3 and 4's 1,756 |
| Scheduling, checks, audio, stroke practice | Yes, for every word you can study | Yes, for every word |
| Browsing and reading every word | Yes, in the app and on a page each on this site | Yes |
| Works offline, no account needed to study | Yes | Yes. Buying needs an account, so the unlock follows you to your other devices |
| Adverts | May appear on the word pages of this site, never inside a study session | None |
How to buy it
- Open Learn Mandarin and go to Progress.
- Sign in, or create an account, in the Account section.
- Tap Unlock HSK 3–4 · $29. Payment is taken by Stripe on its own page, and we never see your card.
- Back in the app, HSK 3 and 4 open once Stripe has confirmed the payment. If they have not opened yet, tap Sync now in Progress. They stay open on every device you sign in on.
What it does not change
Cards you have already studied are never deleted, whether or not you buy. Your progress stays on your device, as it always has. The vocabulary data itself stays under the licence the credits page describes: what the unlock buys is the app's scheduling, checks and progress for HSK 3 and 4, not the words.
Refunds
If the unlock does not work for you, write to [email protected] within 14 days of buying it for a full refund. The Terms of Use set out the rest.
