Questions, answered.

We accept UPI only, processed through our payment partner MMADPay. It works with any UPI app — Google Pay, PhonePe, Paytm, BHIM, or your own bank's UPI service. Because every guide is a digital PDF delivered by email, Cash on Delivery is not available, and there is no convenience fee, handling fee or delivery charge of any kind.

Yes. The entire site runs on HTTPS/TLS encryption. UPI transactions are processed end-to-end by our gateway partner. We do not store any UPI ID, PIN, OTP or banking credentials on our systems — only the transaction reference number for reconciliation.

Your guide is emailed to you within seconds of a successful payment, so the window to cancel is extremely short. An order can be cancelled only while the payment is still pending and the file has not yet been sent — write to support@viintush.com immediately with your order number. Once the ebook has been delivered to your email address, the order is complete and cannot be cancelled, returned or refunded. If you bought the wrong title by mistake, write to us anyway — we will do what we reasonably can to help.

UPI declines are usually caused by bank-side timeouts, your daily UPI limit, an incorrect UPI PIN, or a temporary outage at the UPI app. In these cases no amount is deducted. Simply retry the payment, or switch to a different UPI app or bank account. If money was debited but no ebook arrived, do not pay again — email support@viintush.com with your order number and the UPI reference number. Failed transactions are auto-reversed by your bank, usually within 3–5 working days; where the amount reached us, we refund it in full.

Yes. All prices on the Website are inclusive of GST. A GST invoice showing the tax breakdown is emailed to you along with your ebook. Our GSTIN is 23AAMCV2789G1ZX.

Entirely by email. Every product on this website is a digital ebook in PDF format — nothing is printed, packed or couriered. The moment your UPI payment succeeds, we email the PDF to the address you entered at checkout, as an attachment and as a secure download link. Your email address is your delivery address, so please type it carefully.

It is instant. The email is generated automatically the second the payment gateway confirms your payment — normally within a few seconds. There is no dispatch, no courier and no waiting period. If it has been more than 15 minutes, please check your Spam and Promotions folders first, then write to us.

No. Delivery is free on every order, everywhere. The price you see on the product page is the full amount payable — there is no shipping fee, handling fee, packaging fee or convenience fee.

Yes — a PDF reaches any inbox in the world, so there are no PIN codes, serviceable areas or international restrictions. Please note that payment is accepted over UPI only, which normally requires an Indian bank account.

Each guide is a standard PDF that opens on any phone, tablet, laptop or e-reader — no special app or account required. The page count for each title is stated on its product page before you buy.

First check your Spam, Promotions and Updates folders, and search your inbox for “Viintush”. You can also look up your order at Find My Order using your order number and re-send the download link. If it still has not arrived, email support@viintush.com with your order number and we will re-send it straight away.

Yes. Your purchase does not expire. Keep the delivery email, or use Find My Order at any time to download the PDF again. If a guide is revised, we email you the updated edition free of charge.

No. Digital products cannot be returned or exchanged, and once an ebook has been delivered to your email address it cannot be refunded — the file is yours permanently and cannot be taken back. Please read the description and page count on the product page before you buy. See the full Refund & Cancellation Policy.

Yes, three narrow ones. We refund in full if (1) your payment was taken but no ebook was ever delivered and we cannot deliver it, (2) you were charged twice for the same order, or (3) the file you received is corrupt or unreadable and we are unable to supply a working replacement. Raise any of these within 7 days of purchase at support@viintush.com with your order number.

We acknowledge every request within 2 business days. Where a refund is approved, it is initiated within 5 business days and credited back to the same UPI ID or bank account used for payment; your bank then typically takes a further 5–7 business days to reflect it.

Write to support@viintush.com with your order number and a screenshot of the error. We will send a fresh copy of the file — usually the same working day, and at no cost to you.

No. Your purchase is a single, personal, non-transferable licence to read the guide yourself. Reselling it, uploading it, or re-sharing the PDF or its download link is not permitted and is an infringement of copyright under the Copyright Act, 1957. If you need copies for a team or a classroom, ask us about a bulk licence.
