AI Review hasn't been generated yet

First check your network connection, then tap retry on the results page. Your course answers are already saved on this device, and a failed generation won't affect your course completion status.

How to export or clear data

Go to "Me → Data & Privacy" to export a local backup or clear data saved on the current device.

No practice reminders received

Check the in-app reminder switch and iOS system notification permissions. HappyOS uses local notifications and does not rely on accounts or cloud push.

About privacy and AI data

Daily entries are saved on your device by default. Only when you choose to generate a course AI recap will the course answers needed for it be sent to DeepSeek for processing.
