Frequently asked questions

Yes. The dictionary, HSK lists, pinyin tools, tone practice, shadowing, typing, graded reading, grammar course, component memory, sentence splitter and community pages are free. The local study list and spaced repetition are free too. Pro is optional and adds long-term insights, custom decks, study plans and Smart Review.

No. You can use the free learning tools and save words in this browser without signing in. An account is needed for cross-device sync, the community leaderboard and a Pro subscription. Sign-in uses a one-time code sent to your email; there is no password.

Yes. The site works in current versions of Chrome, Safari, Edge and Firefox on phones, tablets and desktop computers, and there is nothing to install. The tone trainer and shadowing tools ask for microphone permission. Headphones make those exercises easier in a noisy room.

Saved words, review schedules and most progress are stored in this browser on this device. They are not uploaded. Clearing site data, changing browsers or moving to another device can make them appear lost. Sign in to sync across devices, or export your study list before clearing browser data.

When you are signed in, your study list, review schedule, practice history, typing and shadowing results, daily activity and study plan are linked to your account. Opening the same account on another device restores the data that has already synced.

For an account, we store your email address, study progress, subscription status and any weekly-report preference you enable. A session cookie keeps you signed in. We do not store full card details: payments are processed by Creem. The privacy page lists the complete data inventory.

Yes. From Account you can download the data associated with your account as a JSON file or permanently delete the account. Your study list can also be exported as CSV for a spreadsheet or Anki. Account deletion removes the server copy; data already stored locally in your browser remains until you clear it.

The current account is identified by its sign-in email, so changing the address is not available as a self-service action. Contact support with the old and new addresses and do not delete the old account first; we can confirm the safest migration path.

Pro includes four tools: 12-month long-term insights with an in-site weekly report and print-to-PDF, multiple custom decks with CSV/Anki import, a rolling 14-day study plan, and Smart Review with up to three recommended next actions. All existing free tools remain available.

Pro is US$6.99 per month or US$49 per year. The annual plan costs less than twelve monthly payments. The pricing page shows the current plan, and Creem checkout shows the final amount and any applicable tax before you pay.

There is no 7-day Pro trial at launch. You can use the free tools for as long as you like before subscribing, and there is no need to enter payment details to use them.

No. Pro applies only to the site where you purchased it. It does not automatically unlock another language site or a separate future site. Each site has its own subscription and billing record.

Yes. Sign in, open Account, choose Manage billing, then choose Open Creem billing in the secure-billing dialog. In the Creem portal, open Subscriptions, select the active Nihao Pro subscription, choose Manage order or Manage subscription, and use the plan-change option to select the other billing period. The change takes effect immediately and Creem uses prorated billing: the price difference is calculated from the unused time in the current period. Creem shows the exact charge and effective dates before confirmation. A subscription is changed rather than duplicated, so you cannot hold monthly and annual Pro at the same time. If the subscription is already canceling, the portal shows Resubscribe instead; if it has expired, use Start Pro on the pricing page. Always check the amount and renewal date shown by Creem before confirming.

Sign in, open Account and choose Manage billing. The Creem customer portal lets you cancel and view invoices. Cancelling stops the next renewal; access normally continues until the end of the period you have already paid for. Cancelling does not delete your learning data.

1) Sign in and open Account. 2) Under Subscription, choose Manage billing. 3) In the confirmation dialog, choose Open Creem billing; Creem opens in a new tab while this NihaoLearn page stays open. 4) In Creem, open Subscriptions. 5) Select the active Nihao Pro plan. 6) Choose Manage order or Manage subscription. 7) Choose Cancel subscription and confirm. A subscription purchase may show no separate order in the Orders section; that is normal because it is listed under Subscriptions and its payment history is inside the subscription details. After cancellation, the status becomes canceling and Pro remains available through the end of the paid period. If you do not see Cancel subscription, contact support with the subscription email and the Creem order or invoice ID.

Canceling stops future renewals and does not automatically refund the current paid period. Refunds for billing errors, duplicate or unauthorized charges are handled separately, and nothing in this policy limits your rights under applicable consumer law.

There is no free undo after cancellation. Creem shows Resubscribe for a subscription that is still active until the end of its paid period, but choosing it opens a paid checkout for the current price; free trials do not apply. No new charge occurs unless you complete that checkout. The checkout shows the exact amount and effective date before you confirm.

For a duplicate charge, billing error or unauthorized charge, contact support with the email used for the subscription and the Creem order or invoice ID. Creem is the merchant of record and processes eligible refunds to the original payment method. The cancellation and refunds page explains the policy and your consumer-law rights.

The available payment methods are shown by Creem at checkout and can vary by country and currency. NihaoLearn does not receive or store your full card details. Creem handles payment processing, applicable tax and the invoice.

Your data is not deleted and the free tools continue to work. Existing custom decks remain available for viewing, filtering and reviewing, but creating, editing and importing decks is locked. A study plan becomes read-only. Long-term insights and Smart Review need an active Pro subscription again. If you renew, the paid tools become available again.
