Privacy Policy

What we collect

When you use Lumina, we collect:

• Your email address and name if you sign in via Google or email
• The PDF files you upload, temporarily stored to generate study materials
• AI-generated content (summaries, quizzes, flashcards) associated with your documents
• Basic usage data (document count, rate limit records) to operate the service

If you use Lumina without signing in, we create an anonymous session. Anonymous sessions and their documents are automatically deleted after 30 days.

How we use your data

• To generate summaries, quizzes, flashcards, and answers from your PDFs
• To store your documents so you can access them across sessions
• To enforce usage limits and prevent abuse

We do not sell your data to third parties.

Third-party services

Lumina uses the following services to operate:

• OpenAI — generates vector embeddings from your document text to power search
• Google Gemini — generates summaries, quizzes, flashcards, and answers
• AWS S3 — stores your uploaded PDF files
• Supabase — stores document metadata, user accounts, and authentication
• Sentry — captures application errors to help us fix bugs

Your document content is sent to OpenAI and Google Gemini solely to provide the service features. It is not used to train their models under our agreements.

Data retention

Your documents and account data are retained until you delete your account. You can delete your account and all associated data at any time from the dashboard. Anonymous sessions are deleted after 30 days of inactivity.
