Learn Fast sells Energy (credits), a digital good used inside the Service to unlock drills and ask AskThili questions. Because Energy is delivered to your account instantly on payment, all purchases are final and non-refundable, except where a refund is required by applicable law.
Energy is valid for 12 months. Each purchase renews your balance’s validity to 12 months from the purchase date; free Energy is valid for 12 months from signup. Energy left unused past its validity expires. Energy has no cash value, is non-transferable, and cannot be exchanged for money.
There are no subscriptions to cancel — Energy is a one-time top-up, not a recurring charge. Unlocking a drill spends Energy immediately; a spent unlock is not reversible and re-unlocking later costs again.
If you were charged but the Energy did not appear in your balance, or you were charged more than once for the same top-up, email us at support@thili.ai with your payment reference. We will verify with Razorpay and reverse any genuine duplicate or failed-delivery charge to the original payment method, typically within 5–7 business days.
Questions about a payment? Email support@thili.ai. This policy is part of, and read together with, our Terms of Service.
