When a child communicates with or asks Professor X, we will collect the text the child submitted to answer the child’s questions.

When a child submits feedback for the AI-generated answers, we will collect the feedback the child submitted to conduct statistics on users’ satisfaction with AI-generated answers.

We will automatically collect certain information, including CFUUID (only collected in guest mode) and the date the child shoots or imports the photos of math problems, to save the history in chronological order and provide the child with the history record of math problems and answers.

We will automatically collect information, including the date and time of logging in, how many times the child has visited Math-X and the usage of the AI-powered functionalities (including importing/shooting photos of math problems and getting the AI-generated answers, and communicating with or asking Professor X), to calculate the consumption of “Xrystals” and offer “Xrystals” to the child’s account based on the usage.
