ChinaFlashTerms of Use
These terms govern the use of the ChinaFlash app and ChinaFlash Premium. By downloading or using the app, you accept them. If you downloaded it from the App Store, Apple's standard license agreement also applies.
1. What ChinaFlash is
ChinaFlash is an app for learning Chinese vocabulary with flashcards and spaced repetition. HSK 1 is free. ChinaFlash Premium unlocks HSK 2, radical study and the new levels we add.
2. Your license
We give you permission to use the app on your devices for your own learning, for non-commercial purposes. This permission is personal and non-transferable. You may not copy, sell, redistribute or extract the app's content (vocabulary, translations, recordings, illustrations), except as allowed by the third-party licenses listed below.
3. ChinaFlash Premium
- Plans: a monthly subscription, a yearly subscription (with a 7-day free trial the first time) or a lifetime purchase with a single payment. Each plan's price is shown in the app before you confirm.
- Payment: charged by your phone's store (Apple or Google Play) to your account when you confirm the purchase.
- Automatic renewal: subscriptions renew at the end of each period unless cancelled at least 24 hours before the current period ends.
- Free trial: if you don't cancel before the 7 days end, the yearly subscription starts and is charged. If you cancel during the trial, you won't be charged.
- Cancelling: from the subscription settings of your Apple or Google Play account, or from the app in Settings → ChinaFlash Premium → Manage subscription. You keep Premium until the end of the paid period. Deleting the app does not cancel the subscription. The steps are in Support.
- Lifetime purchase: a single payment with no renewals that gives you all of ChinaFlash Premium with that account, including the new levels we add.
- Restoring: on a new phone, or if you reinstall the app, use Settings → ChinaFlash Premium → Restore purchases with the same account.
- Refunds: handled by the store under its own policy; we cannot charge or refund payments directly.
4. Content and rights
The app, its design, texts and translations, illustrations, the Tutu mascot and the voice recordings (made for ChinaFlash with a native Mandarin speaker) belong to ChinaFlash. Some content comes from third parties, under their licenses:
- HSK vocabulary list: complete-hsk-vocabulary (MIT license).
- FSRS review algorithm: ts-fsrs, by Open Spaced Repetition (MIT license).
- Fonts: LXGW WenKai, Noto Serif SC, Ma Shan Zheng, Noto Serif, Fraunces and Nunito (SIL OFL).
HSK is a trademark of its owner. ChinaFlash is not affiliated with or endorsed by the official exam organizers.
5. Fair use
Don't try to bypass purchases, modify the app or use it for anything illegal.
6. What ChinaFlash can and can't promise
ChinaFlash is a study tool. We take care that the content is correct and follows the official HSK 3.0 syllabus, but we can't guarantee it is completely error-free or that you will pass an exam. If you find a mistake, write to us and we'll fix it.
We may improve, change or remove features of the app. Whatever you've paid for will keep working according to your plan.
7. Liability
The app is provided as is. To the extent permitted by law, we are not liable for indirect damages arising from its use. Nothing in these terms limits your statutory rights as a consumer.
8. Changes to these terms
If they change, we will publish the new version on this page with its date. If an important change affects your subscription, we will let you know in the app.
9. Governing law
These terms are governed by Spanish law, without prejudice to the rights granted to you by the law of your country of residence.
