Privacy Policy

Last updated: July 12, 2026

1. What we collect

  • Account info: your email and name, and either a password hash or your Google account identity if you sign in with Google.
  • Uploaded PDFs and the text extracted from them.
  • Chat messages and quiz attempts/answers.
  • Basic usage data (timestamps, feature usage) to keep the service reliable and to improve it.

2. Why we collect it

To run the core service: extracting and embedding PDF content for retrieval, generating AI answers, chapters, and quizzes, maintaining your chat history across sessions, and diagnosing issues.

3. Third parties

Your data is processed by these providers as part of running the service:

  • Google — OAuth sign-in only, if you choose to sign in with Google.
  • Microsoft Azure — hosting, Azure OpenAI (for embeddings and AI answers), Azure SQL (data storage), and Azure Blob Storage (uploaded PDFs).

We do not sell your data to advertisers or unrelated third parties.

4. Data retention

Deleted PDFs and course sessions are soft-deleted and kept for 30 days before being permanently removed. Deleting your account removes your associated data under the same policy.

5. Cookies

We use a session cookie to keep you signed in. We don't use third-party ad-tracking cookies.

6. Your rights

You can delete uploaded PDFs, courses, and sessions at any time from within the app. For full account deletion or any data request not covered by in-app tools, reach us at our contact page.
