Terms of service

Last updated 13 November 2026

These terms cover your use of KnullVoid at knullvoid.tech. By creating an account or using the demo account, you agree to them. If you are under 18, a parent or guardian should read them with you.

What KnullVoid is

KnullVoid is a study aid for CBSE Class 9 and 10 and an introduction to AI for Class 5 and up. It helps you practise and revise. It does not replace your school, your teachers or the NCERT textbooks, and it does not promise any exam result.

Public beta

KnullVoid is in public beta. Features may change, and some chapters are not available yet. We check every solution, but if you find a mistake, please tell us and we will fix it.

Your account

• Give a real email address and keep your password to yourself.
• One account is for one student.
• You can stop using KnullVoid and ask us to delete your account at any time.

Fair use

• Do not copy the question banks, scripts or labs to sell or republish them.
• Do not try to break, overload or get around the limits of the app or the AI teacher.
• Do not use the AI teacher to write work you will hand in as your own.

The AI teacher

The AI teacher is in beta. It can be wrong. Check its hints against your textbook, and ask your teacher when something does not add up.

Paid plans

Student Plus costs ₹299 a month in India or $5 a month elsewhere, billed monthly. You can cancel at any time, and you keep access until the end of the month you paid for. School licences are agreed in writing with each school.

Liability

KnullVoid is provided as it is during the beta. To the extent the law allows, we are not liable for indirect losses from using it. Nothing in these terms limits rights you have under Indian consumer law.
