Terms of Use — Hanzi Practice

Effective: 2026-09-15

Applies to: the Hanzi Practice web app at hanzipractice.app and the Hanzi Practice apps for Android and iOS (the "App"), provided by Space Cats Studios ("we", "us").

1. Acceptance

By installing or using the App you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the App.

2. The service

Hanzi Practice is a Chinese vocabulary and handwriting practice tool. It works offline and stores your progress on your device. We do not provide accounts, and we cannot recover progress that is deleted from your device. Use the in-app export to keep a backup.

3. Free and Premium

The free version includes HSK 1 vocabulary, stroke animation and tracing, a limited daily writing quiz, a limited free-write history, daily goal and basic stats. Premium unlocks the remaining HSK levels, unlimited writing quiz, unlimited free-write history and full stats. The exact features are listed on the Premium screen in the App at the time of purchase.

4. Purchases, subscriptions and refunds

Premium Yearly is an auto-renewing subscription billed once per year. It includes a 7-day free trial for new subscribers. Payment is charged to your Apple ID or Google account at confirmation of purchase, or at the end of the free trial unless you cancel at least 24 hours before the trial ends. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period.
Premium Lifetime is a one-time purchase with no renewal.
Prices are shown in the App in your local currency before you buy and may change; changes never apply to a period you have already paid for.
Manage or cancel subscriptions in your device's App Store or Google Play subscription settings. Uninstalling the App does not cancel a subscription.
Purchases are processed by Apple or Google. Refunds are handled under their policies; we cannot issue refunds directly for store purchases.
Use "Restore purchases" in the App to re-activate Premium on a device that shares the same Apple ID or Google account.

5. Acceptable use

You may use the App for personal, non-commercial study. You may not copy, resell, reverse engineer or redistribute the App or its bundled data except as permitted by the open licenses below.

6. Third-party content and licenses

Dictionary data: CC-CEDICT, licensed under CC BY-SA 4.0.
Stroke order rendering: Hanzi Writer, MIT License.

Those licenses govern that data. Everything else in the App is ours.

7. Disclaimer and limitation of liability

The App is provided "as is" without warranties of any kind. We do not guarantee that it is error-free or that any learning outcome will result. To the fullest extent permitted by law, our total liability to you for any claim relating to the App is limited to the amount you paid us in the 12 months before the claim. Nothing in these Terms limits rights that cannot be limited under the consumer law of your country.

8. Changes and termination

We may update the App or these Terms. Material changes will be posted at hanzipractice.app/terms.html with a new effective date; continued use after that date means you accept the change. We may discontinue the App with reasonable notice; paid Lifetime users will keep access for as long as the App is distributed.

9. Governing law

These Terms are governed by the laws of the Commonwealth of Kentucky, USA, without regard to conflict-of-law rules, except where your local consumer law requires otherwise.
