Support & FAQ

Quick answers for learners around the world—install steps, where progress is stored, Chinese read-aloud (TTS), and how to reach us. Switch to 中文 above if you prefer the family-focused site.

Which platforms are supported?

We ship iOS and Android apps and may provide a web demo depending on deployment. Store links may fail briefly before publication or due to regional availability.

Where is learning progress stored?

Core progress, review/challenge data, nicknames, and simple rewards are stored locally on your device to resume sessions. We do not routinely force-upload this data to our servers in the primary builds unless law requires or you clearly consent.

Why is read-aloud silent?

Speech uses the OS text-to-speech engine and downloaded voices. Enable Chinese TTS voices in system settings, raise media volume, then retry. Restarting the app or updating the OS often fixes edge cases.

How do I report a bug?

Use the store review/developer contact channel or the feedback email/form we publish. Include device model, OS version, app version, steps to reproduce, and screenshots if possible.

Tips for families or younger learners?

Use OS parental controls to manage screen time when children study together with adults. Anyone sharing a device should avoid posting personal details in public reviews.
