Privacy Policy

1. Information We Collect

We collect information in the following categories:

a. Information You Provide

• Uploaded Files: When you upload a presentation (PDF, PPT, etc.), we store the file in Firebase Storage and keep basic metadata (e.g., filename, upload time, file type) in Firestore.
• Account Information: If you sign in with Google OAuth, we collect your name, email address, and profile picture (if available).
• Communications: Any messages, voice recordings, or text queries you send to the AI tutor during a session.

b. Information Collected Automatically

• Usage Data: Device type, browser, IP address, operating system, and interaction data (e.g., slide navigation, timestamps, and progress tracking).
• Voice & Interaction Data: For interactive tutoring sessions, temporary audio data is processed in real-time to provide responses but is not permanently stored unless explicitly needed for analytics or feature improvement.
• Cookies & Analytics: We may use cookies or similar technologies to improve performance and remember your preferences.

2. How We Use Your Information

We use your data to:

• Provide, maintain, and improve our platform features.
• Enable interactive AI tutoring and real-time voice conversations.
• Generate personalized lessons, quizzes, and progress tracking.
• Securely manage uploaded files and user sessions.
• Improve AI accuracy and overall user experience (aggregated and anonymized).
• Communicate updates, new features, or support-related notifications.

We do not sell or rent user data to third parties.

3. Data Storage and Retention

• Files: Uploaded presentations are stored securely in Firebase Storage. Anonymous uploads are deleted after 90 days of inactivity.
• Accounts: Data linked to registered users (via Google OAuth) remains until the user deletes their account.
• Session Data: Temporary voice data is processed in real-time and discarded immediately after interaction, unless anonymized for analytics.
• Backups: We maintain encrypted backups for security and recovery purposes.

4. How We Protect Your Data

We implement strong technical and organizational safeguards including:

• Encryption (in transit and at rest via Firebase Security).
• Access controls and authentication for staff and APIs.
• Regular audits and vulnerability monitoring.
• Anonymization and minimization of sensitive data.

5. Sharing and Disclosure

We only share your information when necessary:

• Service Providers: Firebase (Google Cloud), OpenAI Realtime API, and other processors help deliver core app functionality.
• Legal Compliance: We may disclose data if required by law, subpoena, or government request.
• Aggregated Insights: Non-personal, anonymized usage data may be shared for research or analytics.

We never sell your personal information.

6. Your Rights

Depending on your location (e.g., under GDPR, CCPA), you have rights to:

• Access, update, or delete your personal information.
• Withdraw consent for data processing.
• Export your data.
• Request erasure of uploaded content.

7. Children's Privacy

Teach Me My Slide is not intended for children under 13 years old (or under 16 in the EU) without parental consent. We do not knowingly collect data from minors. If we learn that we have inadvertently collected such data, we will promptly delete it.

8. International Data Transfers

Your data may be stored or processed on servers located in different countries. We ensure such transfers comply with applicable data protection laws (e.g., GDPR Standard Contractual Clauses).
