Privacy Policy

Welcome to Cognitive Horizon, an AI-powered educational platform built for Bangladeshi students (Class 1–10). We are committed to protecting your privacy and handling your information with care and transparency.

This Privacy Policy explains how we collect, use, and protect your personal information when you use our platform at ssitpl.helioho.st.

We collect the following types of information:

• Account Information: Your name, email address, and class level (Class 1–10) when you register.
• Learning Data: Questions you ask, subjects selected, and AI conversation history (for registered users only).
• Technical Data: IP address, browser type, device information collected automatically for security and performance.
• Guest Sessions: If you use Guest Login, we collect only your chosen name and no permanent data.

Your information is used exclusively to:

• Provide personalized AI tutoring tailored to your class level
• Save your conversation history so you can review past sessions
• Improve the quality of our AI responses and platform features
• Ensure security and prevent abuse of our systems
• Send important service-related notifications (if applicable)

We do not sell your personal information to any third parties.

Our AI tutoring engine uses the following third-party AI providers. Your questions may be processed by these services:

• Google Gemini (Google LLC) – Primary AI provider
• Groq (Groq Inc.) – Secondary fallback provider
• Mistral AI (Mistral AI SAS) – Tertiary fallback provider
• OpenRouter / HuggingFace – Emergency fallback providers

Please review their respective privacy policies. We only send the minimum necessary question text; your personal details are never shared with AI providers.

We implement industry-standard security measures including:

• Passwords stored as secure bcrypt hashes — never in plain text
• Session tokens using cryptographically secure random generation
• HTTPS encryption for all data transmission
• Rate limiting to prevent abuse
• Session expiry after 30 days of inactivity

Our platform is designed for students from Class 1 (approximately age 6) and above. We take extra care with younger users:

• Students under 13 should use the platform with parental awareness
• No targeted advertising is shown to any users
• We do not collect more information than necessary for education
• Parents may contact us to review or delete their child's data

You have the right to:

• Access your personal information at any time through your account
• Delete your account and all associated data by contacting us
• Export your conversation history upon request
• Correct any inaccurate information in your profile

We use browser localStorage (not cookies) to store your authentication token locally. This token expires after 30 days. No advertising or tracking cookies are used.

We may update this Privacy Policy from time to time. Significant changes will be announced on the platform. Continued use of the service after changes constitutes acceptance of the updated policy.
