Refund and Cancellation Policy

Last updated: November 2026

This policy covers purchases on ChangYeng (changyeng.in): test unlocks paid by students and subscription plans paid by teachers. All purchases are one-time payments; nothing renews automatically, so there is nothing to cancel.

What you get

Access is delivered digitally and immediately after payment. A test unlock stays on your account; a teacher plan runs for the period you chose (1, 3, 6 or 12 months) from the date of purchase, or from the end of your current plan if you renew early.

When we refund

• You were charged twice for the same item.
• Payment was taken but access was not granted and we cannot fix it.
• A technical fault on our side stopped you using what you bought.

Because access is delivered instantly, purchases are otherwise not refundable once the test has been opened or the plan has started, and unused time on a plan is not refunded.

How to ask

Email [email protected] within 7 days with your account email and payment reference. We reply within 3 working days. Approved refunds go back to the original payment method and normally reach you in 5 to 7 working days, depending on your bank.
