structures.kannamwar.tech is run by Kannamwar Engineering (operated by Kannamwar Engineering LLP). We sell subscriptions to online engineering software only. No physical goods are sold or shipped, and there are no shipping or delivery charges.
How a paid plan is delivered
- The plan is applied to your Kannamwar Engineering account once the payment succeeds. You use it in your web browser at structures.kannamwar.tech after signing in; there is nothing to download, install or post.
- Plans paid online by card, UPI or net banking (through Razorpay) are normally active within a minute of the payment. A plan or team paid by bank transfer or invoice is activated within one working day of the payment reaching us.
- A receipt is emailed to the address used for the payment (by Paddle, our reseller, for payments in currencies other than rupees), and the plan shows under Settings on your account.
- PDF calculation reports you create are downloaded straight from the website to your device.
If your plan is not active
If a paid plan is not active on your account within 24 hours of a successful payment, write to tech@kannamwar.com with the payment ID. We will activate it, or refund the payment in full as set out in our Refund and Cancellation Policy.
Where the service is available
The service is available online worldwide, except where sanctions law forbids it (see the Terms). Customers in India pay in Indian rupees (₹); customers elsewhere pay in US dollars, with any local sales tax, VAT or GST added at checkout.
