Terms of service

Last updated
October 14, 2026

1. Acceptance

These terms govern your use of karnstack.com and the karnstack platform (“karnstack”, “we”, “us”). By creating an account or using the service, you agree to these terms. If you do not agree, do not use the service.

2. The service

karnstack provides online technical video courses, written companions, quizzes, and verified certificates. The content is for your own educational use.

3. Accounts

You can sign in with Google, with a code or link sent to your email, or with a password. We run sign-in ourselves; we never see your Google password, and a password you set is stored only as a salted hash. You are responsible for activity under your account and for keeping your credentials secure. Accounts are for a single person and may not be shared.

4. Plans, billing, and refunds

Access to paid content requires a plan: a monthly or annual all-access subscription, or a one-time all-access lifetime purchase. Subscriptions renew automatically until you cancel; you keep access through the end of the period you paid for. One-time purchases do not renew. Payments are processed by our third-party payment provider, and we do not store your full card details.

If you are not happy, email us within 7 days of a purchase and we will refund it, no questions asked.

5. License and acceptable use

While your access is active (permanently, for lifetime purchases) we grant you a personal, non-exclusive, non-transferable license to access the course content. You may not share, resell, redistribute, scrape, record, or publicly repost course videos, written content, or quizzes, and you may not share account access.

6. Intellectual property

All course content, text, video, graphics, and the karnstack name and marks are owned by karnstack or its licensors. Nothing in these terms transfers any of our intellectual property to you.

7. Acceptable conduct

You agree not to misuse the service, attempt to breach its security or access controls, interfere with its operation, or use it for any unlawful purpose.

8. Termination

We may suspend or terminate access if you breach these terms. You can cancel at any time; cancellation stops future renewals and you keep access until the end of your current period.

9. Disclaimers

The service is provided “as is” and “as available” without warranties of any kind. We do not guarantee that the content is error-free or that it will meet your specific goals.

10. Limitation of liability

To the maximum extent permitted by law, karnstack is not liable for any indirect, incidental, or consequential damages, and our total liability is limited to the amount you paid us in the twelve months before the claim.

11. Changes to these terms

We may update these terms. Material changes will be posted on this page with a new “last updated” date. Continued use of the service after a change means you accept the updated terms.

12. Governing law

These terms are governed by the laws of India, without regard to conflict-of-law rules.
