Privacy Policy

Last updated: 26 July 2026

This Privacy Policy explains how GreyBoxQuant ("we", "us") collects, uses, and protects your personal data when you use our website, courses, and the Trading Lab (the "Services").

1. Information we collect

• Account information you provide — such as your name and email address.
• Usage data — course progress, Trading Lab activity and scores, and interactions with the Services.
• Payment information — processed by our payment processor (Razorpay). We do not store your full card details on our servers.
• Technical data — such as device, browser, and log information, and cookies used to operate and improve the Services.

2. How we use your information

• To provide, personalise, and improve the Services and your learning experience.
• To process payments and manage your access to purchased content.
• To communicate with you about your account, updates, and (if you opt in) new essays and course releases.
• To maintain security, prevent abuse, and comply with legal obligations.

3. Sharing

We do not sell your personal data. We share it only with service providers who help us operate the Services (for example, payment processing and email delivery), and where required by law.

4. Cookies

We use cookies and similar technologies to keep you signed in, remember preferences, and understand usage. You can control cookies through your browser settings; some features may not work without them.

5. Data retention and security

We retain personal data for as long as needed to provide the Services and meet legal obligations, and we apply reasonable safeguards to protect it. No method of transmission or storage is completely secure.

6. Your rights

Subject to applicable law, you may request access to, correction of, or deletion of your personal data, and you may unsubscribe from marketing emails at any time. Contact us using the details below to make a request.
