Refund & Cancellation Policy
This Refund Policy explains when you can obtain a refund from AeroFluid Dynamics, how to request one, and how long it takes. It forms part of our Terms and Conditions.
AeroFluid sells digital products that are delivered immediately on payment. That makes refunds genuinely different from physical goods, and we would rather state the limits plainly before you buy than surprise you afterwards.
01The short version
If we took your money twice, charged you for something you never received, or failed to deliver what the product page promised, you get your money back. If you bought something, used it, and then changed your mind, ordinarily you do not — because digital study material cannot be returned once it has been read.
Every paid product on AeroFluid has free material available before you buy. Please use it. It exists so that you can judge the quality before spending anything.
02What this policy covers
This policy applies to every paid product sold on aerofluid.in and its subdomains, including PYQ Practice access, courses, downloadable ebooks and study material, bundles, and paid sessions where offered.
It does not apply to free material, including the Engineering Labs, free previews and any material distributed at no charge — there is nothing to refund.
03When a refund is available
| Situation | Refund | Window to claim |
|---|---|---|
| Duplicate payment — you were charged more than once for the same product | Full refund of the duplicate amount | Any time |
| Payment taken, access not granted — money debited but the product never appeared in your account | Full refund, or we restore access if you prefer | 7 days |
| Wrong product delivered — you received something other than what you purchased | Full refund or exchange for the correct product | 7 days |
| Technical failure on our side that prevents you using the product and which we cannot resolve within a reasonable period | Full refund | 7 days from the fault being reported |
| Purchased course not released within the period stated on the product page | Full refund of that course, or pro-rata for a bundle | See section 6 |
| Product withdrawn by us within 12 months of your purchase with no equivalent replacement | Pro-rata refund on request | 30 days from withdrawal |
| Unauthorised transaction on your payment instrument, confirmed with your bank or Razorpay | Full refund once verified | Promptly on discovery |
04When a refund is not available
Refunds are ordinarily not available in the following circumstances:
- Change of mind after content has been accessed, downloaded or substantially used;
- Downloaded ebooks and PDFs, once the download has been completed — a file cannot be returned;
- Examination outcome — a result you did not want is not a product defect. We make no promise of any score, rank or selection, as set out in our Terms;
- Insufficient time to use what you bought, or buying close to an examination date;
- Buying the wrong product by mistake where the correct description was shown on the product page — though please contact us, as we will often exchange it;
- Bundles, where part has been consumed — a bundle is priced as a unit and is not refundable in part once used;
- Sessions attended, or missed without notice under section 11;
- Accounts terminated for breach of our Terms, including credential sharing or redistribution of paid material;
- Issues outside our control — your device, your internet connection, or your inability to access the platform for reasons unconnected to our service.
05By product type
PYQ Practice
A free preview is available before purchase. After purchase, a refund is available within 7 days provided you have attempted fewer than 10% of the questions in the subject purchased. Beyond either limit, the purchase is final.
Courses
Refund available within 7 days of purchase provided you have watched less than 20% of the released content of that course. Where a course is sold while still in production, section 6 also applies.
Ebooks and downloadable study material
Because delivery is a file transfer, these are non-refundable once downloaded. If the download link fails, the file is corrupt, or the content does not match the description on the product page, contact us within 7 days and we will repair the delivery or refund in full.
Bundles
A bundle is refundable as a whole under the conditions applying to its components, and only where no component has been downloaded and consumption limits have not been exceeded on any included product.
Mentoring and paid sessions
See section 11 on cancellation and rescheduling.
06Delayed or withdrawn content
Some subjects are described on their product page as being in production, with an indicated release period. If you purchase such a product and it is not released within 60 days of the date indicated on the product page, you may request a full refund of that component, whether or not you have used other parts of your purchase.
Where we withdraw a product entirely and offer no equivalent replacement, purchasers within the preceding twelve months may request a pro-rata refund reflecting the unused portion.
07Duplicate and failed payments
Money debited but payment shown as failed
Where a payment fails at the gateway but your bank has debited the amount, the transaction is ordinarily reversed automatically by your bank or by Razorpay, usually within 5 to 7 working days. No action is required from us for that reversal.
If the amount has not returned after 7 working days, contact us with the date, amount and your bank reference, and we will take it up with Razorpay on your behalf.
Charged twice
Write to us with both transaction references. We refund the duplicate amount in full — there is no time limit and no consumption test for this.
08How to request a refund
Send an email to support@aerofluid.in, or message us on WhatsApp at +91 92203 34442, from or referencing your registered email address, including:
- the registered email address on your AeroFluid account;
- the name of the product purchased;
- the date of purchase and the payment or order reference;
- the reason for the request, with a screenshot where a technical fault is involved.
Requests must be made by the account holder. We may ask for verification before processing.
09Processing and timelines
| Stage | Timeline |
|---|---|
| Acknowledgement of your request | Within 48 hours |
| Decision communicated to you | Within 7 working days of acknowledgement |
| Refund initiated with the payment gateway, once approved | Within 3 working days |
| Amount credited back to you by your bank | Ordinarily 5 to 10 working days after initiation, depending on your bank or card issuer |
The final leg is controlled by your bank, not by us. We will provide the gateway refund reference so you can follow it up directly if needed.
10How refunds are paid
Approved refunds are returned to the original payment method used for the purchase. We do not refund to a different account, card or UPI ID, and we do not issue cash refunds.
Where the original instrument is closed or no longer valid, we will work with Razorpay to identify an acceptable alternative, which may require additional verification from you.
Refunds are made in Indian Rupees for the amount paid. Bank charges, currency conversion differences or gateway fees levied by your own bank are not reimbursed by us.
Where a refund is approved, access to the related content is withdrawn from the account on refund initiation.
11Cancelling before delivery, and paid sessions
Digital products are delivered instantly, so there is ordinarily no window between payment and delivery in which to cancel.
For scheduled sessions, where offered:
- cancellation more than 24 hours before the scheduled time — full refund or free reschedule;
- cancellation within 24 hours — one free reschedule, no refund;
- non-attendance without notice — no refund and no reschedule;
- cancellation by us for any reason — full refund or a reschedule at a time convenient to you, at your choice.
12Chargebacks
If you believe a charge is wrong, please contact us first. We would rather resolve it directly and quickly than through your bank.
Where a chargeback is raised without first contacting us, access to the related content may be suspended while the dispute is investigated. Where a chargeback is found to have been raised without valid grounds, we reserve the right to suspend the account and to recover the amount and any associated gateway charges.
13If you are not satisfied
If your refund request is declined and you believe that decision is wrong, you may escalate it to our Grievance Officer using the details below, stating why you disagree. The Grievance Officer will review the matter independently of the original decision and respond within 30 days.
Nothing in this policy limits your rights as a consumer under the Consumer Protection Act, 2019, including your right to approach the appropriate consumer forum.
14Changes to this policy
We may revise this policy. The version in force at the time of your purchase is the version that applies to that purchase. The revision date at the top of this page shows when the current version took effect.
