Last updated: July 12, 2026

1. Introduction

Welcome to BrainyBee, a service provided by MedCost Data LLC ("we," "our," or "us"). We provide an AI-powered educational platform for exam preparation and coursework analysis. This policy explains how we handle your personal data.

2. Information We Collect

• Account Data: Name, email, and profile picture via Google Sign-In.
• User Content: Coursework, notes, and documents you upload for AI analysis.
• Usage Data: Test scores and interaction logs to improve the AI models.

3. How We Share Data (AI Processors)

To provide our services, we send the content you upload (such as study notes) to third-party Large Language Model (LLM) providers, including Google Vertex AI, OpenAI, and models routed through OpenRouter, for processing.

• For services processed using Google Vertex AI and OpenAI under our configured business and API terms, your prompts and responses are not used to train their public models.
• The free Nemotron tutor is an exception: free-tier chats routed through OpenRouter and its upstream model provider may be logged, retained, or used for model training or improvement. Avoid sharing sensitive or confidential information in free-tier tutor chats.
• For paid OpenRouter fallback routes, we request zero-data-retention processing where the selected provider supports it.
• We do not sell your personal data to advertisers or data brokers.
