Schools and universities get institutional pricing — contact us via the Schools page for a quote. Individual student discounts are not available — Pro works out to about $5/month on the annual plan — less than ten minutes of private tutoring.
We use Stripe. Major credit and debit cards, Apple Pay, Google Pay, Alipay, and WeChat Pay — the exact options depend on your country. Alipay and WeChat Pay can’t auto-renew, so they appear only under “One year”. We never store card numbers.
Yes. You can upgrade from Free to Standard or Pro at any time, and the price is prorated against your remaining period. Downgrades take effect at the next renewal.
Your study history, vocabulary progress, and account remain intact. You lose access to features that aren't in the new plan (e.g., Pro voice conversation if you downgrade to Standard) but your data stays on your account.
