Privacy Policy

1. Introduction

Bachu ("we", "our") is an AI-powered educational tutor designed for children. We value the trust you place in us to help your child learn. This Privacy Policy explains what data we collect, how we use it, and your rights as a parent.

We operate under a strict "Parent-First" philosophy: You own your data, and we do not sell it to advertisers.

We comply with the Children's Online Privacy Protection Act (COPPA) and relevant data protection regulations. This service is intended for children under parental supervision.

2. Information We Collect

A. Information You Provide

• Parent Account: We collect your name and email address to create your account and send important service updates.
• Student Profile: We collect your child's first name (or nickname) and grade level to personalize the tutoring experience.
• Chat Data: We store the text conversation history between your child and the AI tutor to maintain context (e.g., remembering a math problem from yesterday) and to show you the history in the Parent Dashboard. Chat data is retained until you delete your account.

B. Voice & Worksheets

• Voice Input: When your child uses the microphone, audio is sent to our AI partner for transcription and immediately discarded. We do not store audio recordings.
• Worksheet Uploads: Images or PDFs uploaded for homework help are stored securely in encrypted storage for the duration of the tutoring session. These files are accessible only to you and your child via the Parent Dashboard, and can be deleted upon request.

C. Technical Data (For App Performance)

• Usage Stats: We use Vercel Analytics to track anonymous performance data (e.g., "Page load speed") to improve the app experience. This data is aggregated and does not identify individuals.
• Crash Reports: We use Sentry to automatically detect software bugs. If the app crashes, a technical report is sent to us so we can fix it. We strip personal identifiers from these reports wherever possible.

3. How We Use Artificial Intelligence

Bachu uses enterprise-grade Artificial Intelligence to function. We have strict data agreements with our providers:

• Google Gemini (Chat & Vision): Used for the main tutoring conversation and reading worksheets. We use a paid commercial license, which ensures your data is NOT used to train their public models.
• OpenAI (Voice): Used for text-to-speech (reading responses aloud) and speech-to-text (voice input). We use a commercial license, which ensures your data is NOT used to train their public models.

4. How We Share Data

We do not sell, rent, or trade user data. We only share data with the following "Service Providers" necessary to run the app:

• Supabase: Secure database hosting (Encrypted)
• OpenAI / Google: AI processing (Data is transient and private)
• Vercel: Website hosting and analytics
• Sentry: Error tracking

5. Parental Rights & Control

As a parent, you have full control:

• View Data: You can read every message your child sends and receives via the Parent Dashboard.
• Delete Data: You may request the complete deletion of your account and all associated child data at any time. Please contact us, and we will wipe it from our servers immediately.

6. Data Security

We use industry-standard encryption (SSL/TLS) for data in transit and secure database encryption for data at rest. While no service is 100% immune to attacks, we prioritize security at every layer of our infrastructure.
