Privacy Policy

We process account information such as your email address, authentication identity, and profile details you choose to add. We also keep learning information needed to provide the service, including progress and practice results.

When you use a learning feature, we may store the text and results needed to show feedback, let you continue practice, and remember completed work.

We use this information to authenticate you, provide and improve learning features, remember your progress, protect the service from abuse, and administer accounts and feature access.

We may also record limited technical and security information, such as request metadata, device/browser information, and IP address, to operate, diagnose, and protect the service.

Current learning feedback uses the application's reviewed content and deterministic rules. The application does not send learner answers to an AI provider for feedback.

We use Supabase to provide authentication and database services. Google may process authentication information when you choose Google sign-in.

You can update information available in your profile. For account, privacy, or deletion requests, contact nguyenluthao252@gmail.com. We may need to verify that a request relates to your account before acting on it.

We retain account and learning information while it is needed to operate your account and the features you use, subject to legitimate security and operational needs. We may update this policy as the service changes; the date above shows the latest revision.

Cô Bình Tiếng Anh is an educational service and is not presented as a child-directed account service. Parents or guardians with questions about an account can contact nguyenluthao252@gmail.com.
