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.
Third-Party Services
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
- Google Analytics — Used to understand app usage patterns anonymously. Privacy Policy
- OpenRouter / AI API — Used to power the AI Tutor Chat feature. Only the text of your question is sent. No personal data is transmitted. Privacy Policy

Location Data

Data Sharing
We do not sell or share your personally identifiable information with third parties for marketing purposes. Anonymous usage and diagnostic data may be shared with the third-party services listed above strictly for operational and improvement purposes.
Data Security
We take reasonable steps to protect your information using commercially acceptable security measures. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.
Children’s Privacy
Our apps are designed for students and are suitable for all ages. We do not knowingly collect personally identifiable information from children under 13. If you believe your child has provided us with personal information, please contact us and we will promptly delete it.
