Do I need an internet connection?

The first lesson download needs a connection. After that the app works offline. If lessons are updated, the app fetches the new version the next time it opens.

Do I need an account?

No. There is no login, and learning progress stays on your device.

How do I change the language?

Open Settings → Language and choose Follow phone, Traditional Chinese, Simplified Chinese, or English.

Why are some chapters not available yet?

Lessons are released in batches. Open chapters are complete; later chapters appear in the learning path when they are ready.

Is my learning progress uploaded?

No. Progress, answers, and settings stay on the device. The server records only the usage statistics needed to deliver content; see the Privacy Policy.

Can I request deletion of my data?

Yes. Email us with the installation identifier shown on the app's Settings page and we will help.
