Privacy Policy

Effective Date: May 29, 2025

Overview

This app does not collect or store any personally identifiable information (PII) such as name, email, or location. Your usage is completely anonymous and local to your device unless stated otherwise below.

Data Collection

We collect minimal and non-personal usage data for analytical and improvement purposes. Specifically:

• Topic Views: We gather topic view statistics as a list. This helps us understand which topics are most accessed.
• Mistaken Questions: We collect questions which users commonly get wrong. This helps identify difficult areas that might need clarification or improvement.
• UUID (Universally Unique Identifier): The application sends the UUID in the request headers. This is used only to differentiate devices, not users. We do not store or log this UUID in our systems. It is not used to track or profile users.

Use of Collected Data

Collected data is used solely to enhance app performance and content. Examples include:

• Determining popular topics for better suggestions
• Improving question accuracy based on frequent mistakes

This data is processed anonymously and in aggregate. It is never linked to any user identity.

Offline Storage

The application stores its content locally on your device for offline access. Your interaction history is also kept locally. We do not access, transmit, or upload this local data.

Feedback and Suggestions

You may optionally send feedback or suggestions. These are submitted without any personal data. They are reviewed collectively for content improvement and product development purposes.

Accounts

No account is required to use the app. There is no login or authentication system. Everything functions without identifying or registering the user.

Data Retention

All content is downloaded once and kept on your device. Usage data sent to the backend is retained only for statistical aggregation. There is no historical user-based log or individual profiling.

Third-Party Sharing

We do not share your data with any third-party services or advertisers. There are no analytics SDKs, tracking pixels, or external data processors embedded in the app.

Security

While your data stays local and minimal anonymous usage data is transmitted, all communication is encrypted using HTTPS to protect the integrity and confidentiality of transmitted data.

Changes to This Privacy Policy

This Privacy Policy may be updated from time to time. Any changes will be reflected within the app or on the designated privacy page. Continued use of the app after updates constitutes acceptance of the new policy.
