Language and AI practice

Select your interface language in Settings. Choose your HSK level and learning goal to personalize practice. Online AI chat and word explanations require internet access and explicit consent. AI responses can be inaccurate; use them as learning assistance. The app is intended for adults aged 18 and over.

Microphone and speech recognition

Allow microphone and speech recognition when using voice input. You can manage permissions in iOS Settings. Keyboard input remains available if you decline these permissions.

Premium and restoring purchases

Weekly and monthly Premium plans provide the same Premium access. The price and billing period are shown before purchase. If an existing purchase is not recognized, open the Premium screen and choose Restore Purchases using the same Apple Account used to buy the subscription.

Manage or cancel a subscription

Open iOS Settings, tap your Apple Account, then Subscriptions, and select Speak Chinese AI. Subscriptions renew automatically unless canceled. Deleting the app or your app account does not cancel an Apple subscription.

Delete your app account

Use Delete Account in the app's Settings. This removes the app profile and saved corrections from Firebase and clears local app history. Purchase records and data retained by service providers may remain under their policies. Contact support for help with a privacy request.
