Each round includes all earlier words. Use the marked-word list for a shorter review. The current development packs contain repeated sample data, not a reviewed exam corpus.
Your learning, on your device
Progress is stored on the device. Resetting a grade clears its learning progress and marks. momo has no account-based recovery or cross-device sync; reinstalling or changing devices can lose local records.
Before the first release
Purchases are not enabled in this development build. When products are offered, the store purchase screen will show their price and scope. Restore uses the same store account and the same app; JLPT and HSK purchases are separate.
Privacy policy
Usage sharing is optional. Turn it off in Settings to stop future analytics and reset the local analytics identifier. This does not immediately erase reports already sent to Google. Usage sharing is offered only to people aged 14 or older.
