  • Copy & Share: Copy text for notes or send directly to the AI Tutor.

Information We Collect

1. Personal Information

We do not directly collect personally identifiable information such as your name, address, phone number, or email address.

2. AI Feature Data

When you use the AI Tutor Chat, your typed question is sent to a third-party AI API (via a Firebase Cloud Function) to generate a response. We do not store or share the content of your questions beyond what is needed to generate the reply. Summaries and quizzes are pre-generated and served from our database — no user content is sent to the AI for these features.

3. Log Data

In the case of an error, we collect diagnostic data through third-party services (such as Firebase Crashlytics). This may include your device’s IP address, device name, operating system version, app configuration, time and date of use, and other statistics. This data is used solely for debugging and improving the app.

4. Usage Analytics

We use Google Analytics (Firebase Analytics) to collect anonymous usage data such as screen views and session duration. This helps us understand how the app is used and improve future updates. No personally identifiable information is included.

Permissions

READ PHONE STATE: Used to pause reading when a phone call is received and to resume when the call ends.

INTERNET: Required for downloading textbook content, displaying ads, AI Tutor Chat, and first-time generation of AI summaries and quizzes. All downloaded content is accessible offline after the initial download.

Our apps use the following third-party services, each governed by their own privacy policies:

  • AdMob (Google) — Used to display advertisements. Privacy Policy
  • Firebase (Google) — Used for crash reporting, analytics, remote configuration, cloud functions, and Firestore database. Privacy Policy
