Privacy Policy

Last updated: April 13, 2026

1. Introduction

AI Sprout ("we," "us," or "our") operates the website aisprout.app (the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Service.

2. Information We Collect

Account Information

When you create an account, we collect your email address, name, and authentication credentials through our authentication provider (Supabase). If you sign in with Google or GitHub, we receive your name, email, and profile picture from those services.

Learning Data

We collect data about your learning progress, including:

  • Lessons viewed and completed
  • Quiz answers and scores
  • Concept mastery levels
  • Streak and XP data
  • Assignment submissions and AI evaluation results
  • AI copilot conversation history (within a session)

Onboarding Preferences

During onboarding, we collect your technical background, AI familiarity level, learning goals, preferred analogy domain, and available daily learning time. This data is used to personalize your experience.

Usage Data

We automatically collect certain information when you access the Service, including your browser type, device type, pages visited, and time spent on pages.

3. How We Use Your Information

We use the information we collect to:

  • Provide and maintain the Service
  • Personalize your learning experience (adaptive quizzes, spaced repetition)
  • Track your progress across devices
  • Evaluate assignment submissions using AI
  • Improve our curriculum and features
  • Communicate with you about your account or the Service

4. AI-Powered Features

AI Sprout uses AI language models (via LiteLLM proxy) for the following features:

  • AI Copilot: Your questions and the current lesson context are sent to an AI model to generate responses. Conversations are not stored permanently.
  • Assignment Evaluation: Your assignment submissions are sent to an AI model for grading and feedback.
  • Explain It Back: Your written explanations are sent to an AI model for evaluation against rubrics.

We do not use your personal data to train AI models. Your submissions are processed in real-time and not retained by the AI provider beyond the request.

5. Data Storage and Security

Your data is stored in two locations:

  • Browser localStorage: For instant access and offline capability. This data is stored on your device only.
  • Supabase (cloud): For cross-device sync and data persistence. Supabase provides encryption at rest and in transit.

We implement appropriate technical and organizational measures to protect your data. However, no method of transmission over the Internet is 100% secure.

6. Third-Party Services

We use the following third-party services:

  • Supabase: Authentication and database hosting
  • Vercel: Website hosting and deployment
  • Google / GitHub: OAuth authentication (optional)
  • LiteLLM / AI providers: AI-powered features (copilot, evaluation)

Each third-party service has its own privacy policy governing the use of your information.

7. Your Rights

You have the right to:

  • Access: Request a copy of the data we hold about you
  • Correction: Request correction of inaccurate data
  • Deletion: Request deletion of your account and associated data
  • Portability: Request your data in a machine-readable format
  • Opt-out: You can clear your localStorage at any time to remove local data

To exercise these rights, contact us at the email address provided below.

8. Cookies

We use essential cookies for authentication (Supabase session tokens). We do not use tracking cookies or third-party advertising cookies. LocalStorage is used for learning progress data, not tracking.

9. Children's Privacy

AI Sprout is designed to be accessible to learners aged 15 and above. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
