Terms of Use

Last updated: 15 October 2026

These terms are an agreement between you and 4BitStack ("we", "us") for using ChalkPilot, on the website chalkpilot.ai or in the ChalkPilot desktop app. By creating your account you agree to them, and to our Privacy Policy, which explains how we handle your data.

1. Who can use ChalkPilot

• ChalkPilot is for students and learners. If you are under 18, a parent or guardian must read and agree to these terms for you, and is responsible for how you use ChalkPilot.
• You must give true details when you set up your profile.

2. Your account

• Your account is for you alone. Do not share it, or the key that signs you in, with anyone.
• You are responsible for what is done with your account. Tell us through Support straight away if you think someone else has used it.
• We may disable an account that breaks these terms, or that is used in a way that harms ChalkPilot or other people.

3. An AI teacher

• Your lectures, answers, notes and quizzes are written and spoken by artificial intelligence. They can contain mistakes, leave things out or be out of date.
• ChalkPilot helps you learn. It does not replace your school, your teachers, your textbooks or your exam board's official material. Check anything important, especially before an exam.
• Do not rely on ChalkPilot for medical, legal, financial or safety advice.

4. Credits and payments

• Classes, notes and quizzes use credits as they are written and spoken. The app shows how many credits you have and have used.
• New accounts may receive free credits. Free credits have no cash value and cannot be transferred.
• You can buy more credits in the app. Payments are handled by Razorpay. Prices are shown before you pay, and may change for future purchases.
• Credits are not refundable once used. If a payment went wrong, or you were charged but did not receive your credits, write to Support and we will put it right. Other refunds are at our discretion, except where the law gives you a right to one.
• Credits cannot be exchanged for money.

5. Using ChalkPilot fairly

You agree not to:

• use ChalkPilot for anything unlawful, or to create content that is hateful, sexual, violent, harassing or harmful to others;
• try to make the teacher produce such content, or get around the limits built into ChalkPilot;
• copy, sell or resell ChalkPilot or its lectures as a service of your own;
• access ChalkPilot with automated tools, overload it, or try to break into it or to find out how it is built;
• pretend to be someone else, or use another person's account.

6. Content

• What you type or say stays yours. You allow us to use it to run ChalkPilot for you, as described in the Privacy Policy.
• The lectures, notes and quizzes written for you are for your own learning. You may keep them, print them and share them for non-commercial study.
• ChalkPilot itself, its name, look, software and teaching material belong to 4BitStack.

7. The service

• We work to keep ChalkPilot available and correct, but it is provided "as is". It may sometimes be unavailable, slow or wrong, and we may change, add or remove features.
• You can stop using ChalkPilot at any time, and ask us through Support to delete your account.
• If we stop offering ChalkPilot, we will tell you in advance where we can.

8. Limits of our responsibility

As far as the law allows, we are not responsible for indirect losses, such as lost marks, lost opportunities or lost data, that come from using ChalkPilot or from mistakes in what it teaches. Our total responsibility to you for any claim is limited to what you paid us in the three months before it. Nothing in these terms takes away a right you have under consumer law that cannot be taken away.

9. Changes to these terms

We may update these terms. We will change the date at the top of this page, and tell you in the app about important changes before they apply to you. If you go on using ChalkPilot after that, you accept the new terms.

10. Law

These terms are governed by the laws of India, and the courts of India decide any dispute about them.
