Privacy Policy

• The email and display name you provide when signing up.
• Passwords in hashed form; the platform never stores or logs raw passwords.
• Login sessions, as hashed tokens with session expiry.
• Resources you favorite and your resource-opening history.
• Feedback content you voluntarily send.
• Minimal usage events to improve resources, such as opening a resource or sending feedback.

When a resource hits a technical error, the platform only records a truncated error message and does not keep stack traces.

• IP addresses and browser information.
• Phone numbers.
• Your school, class or organization information.
• Grades, assessment results or personal learning data.

Data is only used to maintain your login, show your favorites and history, process feedback and improve resource quality. We do not sell user data and do not use it for advertising.

Passwords are hashed with random salt; your browser only receives a session token as an HttpOnly cookie. When you change or reset your password, all sessions for the account are revoked.

You can request access to or deletion of your account data by contacting hello@digitallearning.vn.
