Each account is for a single individual. You agree not to:

• Share your Pro account credentials with others, or use one account for multiple people
• Scrape, copy, or systematically download content from the platform

• Reverse engineer the Service or attempt to extract, harvest, or bulk-export its underlying data
• Use any content (problems, solutions, tests, or course material) to train, build, seed, or improve a competing or derivative product, model, or dataset
• Use the Service for any unlawful purpose
• Redistribute, resell, or publish problem content or solutions on other platforms

We actively monitor for abuse. Violations may result in immediate suspension or termination of your account without refund, blocking of offending IP addresses or devices, and pursuit of all available legal remedies, including under applicable computer-fraud, contract, and copyright law.

7. Disclaimer of Warranties

The Service is provided "as is" without warranties of any kind. QuantVault does not guarantee that use of the Service will result in interview success or employment offers.

8. Limitation of Liability

To the maximum extent permitted by law, QuantVault shall not be liable for any indirect, incidental, or consequential damages arising from your use of the Service.
