1. Information we collect

1. Account information: Depending on how you register, we collect your phone number or, with your authorization, your account identifier, display name, and profile picture through WeChat or Google.

Platform administrators can view them only as needed to provide technical support or handle feedback, and if a project is an assignment you submitted to your teacher, your teacher can view it too. If we ever add project sharing, we will tell you in advance and ask for your consent separately.

3. Interaction information: We save your conversations with the AI tutor (including typed text, text transcribed from voice input, and any screenshots or images you add) and the related code, to provide personalized guidance and improve our services. Voice input is recognized by Alibaba Cloud's speech service. Your browser sends the audio directly to Alibaba Cloud; we receive only the transcribed text and do not store the audio.

4. Device information: Device model, operating system, browser type, IP address, and device identifiers, used to improve your experience and protect account security.

5. Student account information: For student accounts created by a teacher or school, we collect the student's name or nickname, class, and sign-in account provided by the teacher, along with the student's assignment submissions and grading results.
