Q. How is the Master Mode study history saved?

A. There are two ways to save the study history.

1. If you are using QuizGenerator only (uploading to a regular web server)
　The data is stored in the browser's local storage.
　If you explicitly erase the browser's local storage, or if you learn in private mode (no history), the history will be lost, though,
　It will not be reset by restarting the browser or restarting the phone.

2. If you use learningBOX
　The data is stored in the learningBOX grade data, and the learning history is carried over to different browsers and smartphones/PCs as long as the user has the same account.
