Terms of Use

Last updated: November 2026

These terms govern your use of ChangYeng (changyeng.in), operated by ChangYeng (changyeng.in) ("we", "us"). By creating an account or using the site you agree to them.

1. Accounts

Give accurate information, keep your password private and tell us if you think your account was misused. You are responsible for activity on your account. If you are under 18, use the site with the consent of a parent or guardian.

2. Tests and payments

Some tests are free, in full or in part. Other tests are unlocked for your account after payment. Prices are shown before you pay, and payments are processed securely by Razorpay. An unlocked test is for your personal use only; do not share your account or copy test content.

3. Classes and teachers

A teacher can invite students to a class with a class code. Exams a teacher schedules for the class are available to its members at no charge, for as long as the teacher's subscription is active. Teachers can see the names and results of students in their classes.

4. Teacher subscriptions

Teachers buy access for 1, 3, 6 or 12 months. Plans are one-time purchases and do not renew automatically. Teachers are responsible for the questions, pictures, links and other material they add, and confirm they have the right to use it. We may remove material or suspend accounts that break these terms or the law.

5. Acceptable use

Do not try to bypass payments or limits, access other people's data, disrupt the service, upload harmful or unlawful content, or collect content from the site by automated means.

6. Practice material only

Our tests are for practice. We try to keep them accurate and up to date, but we do not guarantee that they match any syllabus or predict any exam result.

7. Intellectual property

The site, its design and the tests we provide belong to us or our licensors. Teachers keep the rights in the material they create and allow us to show it to their students.

8. Changes and availability

We may improve, change or pause parts of the service, and we may update these terms. Continued use after an update means you accept it.

9. Liability

The service is provided "as is". To the extent the law allows, we are not liable for indirect or consequential losses, and our total liability for any claim is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits rights you have under law that cannot be excluded.

10. Governing law and contact

These terms are governed by the laws of India. Questions: [email protected].
