ChinaFlashPrivacy policy
ChinaFlash is an app for learning Chinese. It is designed to work without collecting personal data: you don't need an account and we don't send your information to any server.
What data is stored
Your study progress (which words you have reviewed, when they are due again, your streak, your test results) and your preferences (theme, font style, sound, language) are stored only on your device. We never receive them and cannot access them. If you delete the app, this data is deleted with it.
What data we don't collect
ChinaFlash does not collect your name, email address, location, contacts, advertising identifiers or usage data. It contains no ads, no analytics and no tracking across apps or websites.
Purchases
ChinaFlash Premium is bought through your phone's store (the App Store on iPhone, Google Play on Android), as a monthly subscription, a yearly subscription with a 7-day free trial or a lifetime purchase. The store handles the payment, automatic renewal and cancellation with your account, under its own privacy policy; we never receive your payment details or your identity.
To know whether you have Premium, the app asks the store which purchases your account owns when it opens and when you come back to it. That answer is only used on your phone to unlock the content. You can cancel a subscription at any time from your Apple or Google Play account settings; we explain it step by step in Support.
Audio and content
Pronunciation recordings, fonts and vocabulary are included inside the app: nothing is downloaded or sent when you listen to a word. The recordings are ChinaFlash's own, made with a native Mandarin speaker.
App updates
When it opens, the app asks Expo's servers (the service we use to publish fixes) whether there is an update. That request only carries technical data: the app version, the phone's operating system and a random installation identifier that is not linked to you. It does not include your progress or any personal data.
