Privacy Policy

Last updated: 2026

Your privacy is important to us. This Privacy Policy explains what information we collect, how we use it, and what rights you have.

Information We Collect

We may collect basic account information such as your email address, name, and profile details when you create an account.

We also collect usage data, such as how you interact with lessons, videos, and features, to improve the learning experience.

Quiz App Data

The Kaja Korean quiz app does not require an account. It may use a random device identifier and quiz activity to serve questions, remember difficulty preferences, and improve learning progress. Favorites and history may also be stored locally on your device.

If you enable study reminders, we may store a push notification token solely to deliver those reminders. You can disable notifications in your device settings.

How We Use Your Information

We use your information to:

• Provide and operate the service
• Improve lessons and user experience
• Communicate important updates
• Ensure the security of your account

Data Sharing

We do not sell your personal information.

We may use trusted third-party services (such as hosting, authentication, and analytics providers) to operate the service. These providers only access data necessary to perform their function.

Your Rights

You can request access, correction, or deletion of your data at any time.
