  • Log data: IP address, access timestamps, and referring URLs.

3. How We Use Your Information

We use your information to:

  • Provide, maintain, and improve the Platform and its features.
  • Generate personalised study plans, recommendations, and diagnostic reports.
  • Power AI-driven features such as the doubt solver and adaptive practice engine.

  • Detect and prevent fraud, abuse, or security incidents.

4. Third-Party Services

We use the following third-party services to operate the Platform:

  • Supabase: Cloud database and authentication provider. Your account data, study progress, and test records are stored on Supabase infrastructure. Supabase processes data in compliance with their privacy policy and applicable data protection laws.
  • Anthropic (Claude AI): Powers our AI-driven features including study plan generation, doubt solving, and question explanations. When you interact with AI features, relevant context (such as your question or topic) is sent to Anthropic's API for processing. Anthropic does not use this data to train their models.
  • Google Analytics: We use Google Analytics to understand aggregate usage patterns and improve the Platform. This may collect anonymised browsing data.
  • Vercel: Our hosting provider. Vercel processes web requests and may log IP addresses and request metadata for security and performance purposes.

5. Cookies & Local Storage

We use the following types of cookies and browser storage:

  • Essential cookies: Required for authentication, session management, and security. These cannot be disabled.
  • Functional storage: Stores your preferences such as theme settings and last-visited pages.
  • Analytics cookies: Google Analytics cookies that help us understand usage patterns. You can opt out via your browser settings or Google's opt-out tool.

We do not use advertising cookies or sell your data to advertisers.

6. Data Security

We implement industry-standard security measures to protect your data, including encryption in transit (TLS/HTTPS), secure authentication via Supabase Auth with Row-Level Security (RLS) policies, and regular security reviews. However, no method of transmission or storage is 100% secure. We cannot guarantee absolute security of your information.

7. Data Retention

We retain your account data and study progress for as long as your account is active. If you delete your account, we will remove your personal data within 30 days, except where retention is required by law or for legitimate business purposes (e.g., anonymised aggregate analytics). Anonymised data that cannot identify you may be retained indefinitely.
