Terms of use and sale

Last updated 10 November 2026

1. Who we are

codewithvinay.com is run by Vinay Singh, an individual based in India (“we”, “us”). Contact details are on the contact page. By using this site or buying from it you agree to these terms.

2. What we sell

Practice books for ICSE Computer Applications and ISC Computer Science: for each mock-paper book, a free sampler PDF and a complete edition sold as a PDF on this site and as a printed paperback through Pothi.com; and the free PDF of Pragmatic Solutions to ISC Computer Science Practical Problems, whose printed paperback is sold by Notion Press, Amazon and Flipkart. Printed copies are sold, printed and shipped by those stores under their own terms.

3. Prices and payment

Prices are in Indian rupees and are shown before you pay. Payments are processed by Razorpay; we never see or store your card, UPI or bank details. An order is confirmed only when Razorpay confirms the payment to us.

4. Your licence for a purchased PDF

• When you buy a PDF you get a personal, non-transferable licence to read it on your own devices and print it for your own study.
• You may not share, upload, email, sell, rent or otherwise distribute the file or printouts of it, or remove the name and order details printed on its pages.
• Each PDF is prepared for its buyer and shows your name, a partly hidden email address and your order number on every page. If a copy is found being shared, we may disable your download links and take other lawful action.

5. The free PDFs

You may share the free PDFs (the samplers and Pragmatic Solutions) with others, unchanged and free of charge. You may not sell it, edit it, or remove the author's name or website from it.

6. Copyright

All questions, solutions, programs and analysis in the books are original work and © Vinay Singh. All rights not expressly granted are reserved.

7. Independence from CISCE

These are independent practice papers. They are not affiliated with, endorsed by, or produced by the Council for the Indian School Certificate Examinations (CISCE). The board-paper analysis lists only facts such as year, question number, marks and topic; it does not reproduce board questions.

8. Accuracy and no guarantee of results

Answers are checked carefully, and many are checked by computer, but mistakes are possible. Corrections will be published on this site. The books are for practice: we don't promise that any question will appear in an examination, or any particular marks or result.

9. Delivery, refunds and cancellations

See the delivery policy and the refund and cancellation policy.

10. Liability

To the extent the law allows, our total liability for any claim about a purchase is limited to the amount you paid for it.

11. Changes

We may update these terms. The version shown when you place an order applies to that order.

12. Law and disputes

These terms are governed by the laws of India. Courts at Prayagraj, Uttar Pradesh, have jurisdiction, without affecting any right you have under consumer protection law to bring a complaint where you live.
