Refund and cancellation policy

Last updated 23 October 2026

Please read this before buying Pro. It's short.

What you buy

Pro is access to the whole course for a fixed period: ₹299 for 30 days or ₹1,999 for 365 days, prices including all charges. Access starts as soon as the payment is confirmed. Most of the course is free to try first (the first chapters, two interview problems, the question bank and Daily Design), so you can decide whether Pro is right for you before paying.

No automatic renewal, nothing to cancel

Each payment is a one-time purchase. We never charge you again automatically and we don't keep your card. When your period ends, your account simply returns to the free plan, with all your progress kept. There is no subscription to cancel.

Refunds

All payments are final and non-refundable. Because Pro gives instant access to all of the digital content, we don't offer refunds for change of mind, unused time, or partial periods. This is shown, and you confirm it, before you pay.

The only exceptions:

Approved refunds are sent back to the original payment method through Razorpay and usually arrive within 5 to 7 working days, depending on your bank.

How to reach us

Write to us from the email address on your account, with the payment ID (it starts with pay_ and is shown on your Pro page and in Razorpay's receipt). We reply within 2 working days.
