This policy applies to every paid plan bought on structures.kannamwar.tech, which is run by Kannamwar Engineering (operated by Kannamwar Engineering LLP) ("Kannamwar Engineering", "we", "us"). It forms part of our Terms and Conditions.
Orders paid in a currency other than Indian rupees are sold by our online reseller, Paddle.com Market Limited ("Paddle"), which is the Merchant of Record for those orders. For those orders Paddle takes the payment and handles refunds and billing questions, under this policy and Paddle's Buyer Terms.
Free trial
Every new account starts with seven days of Professional access. No payment details are asked for, and the trial never turns into a paid plan by itself: when it ends the account moves to Free Explorer unless you choose a paid plan. If you buy a plan during the trial, your payment method is saved then (a small authorisation charge, refunded at once) and the first payment is taken only when the trial ends; cancel before then and nothing is charged.
Cancelling a subscription
- You can cancel a Starter, Professional or Team subscription at any time from Settings on your account (for a Team, from Organisation → Billing). You can also write to tech@kannamwar.com from the email address on your account; we confirm a cancellation by email within two working days.
- If you paid through Paddle you can also cancel from the link in your Paddle receipt or at paddle.net.
- There are no cancellation fees and no minimum term.
- A cancellation takes effect at the end of the billing period (month or year) you have already paid for. Your plan stays active until then, it is not renewed, and you are not charged again.
- When the plan ends your account stays open on Free Explorer. Saved models and sections remain in your account and can still be listed and opened; see the Pricing page for what Free Explorer includes.
- For a Team, only the team's owner can cancel.
- Switching plan. Moving to another plan, billing period or number of seats starts a new subscription at once. The old one ends at the same moment and the unused part of its last payment is refunded automatically, to the account it came from.
Refunds
- Changed your mind? You can ask for a full refund of any payment within 14 days of the date it was made, for any reason. The plan that payment bought ends when the refund is made.
- After 14 days we do not refund the unused part of a month or year, but cancelling stops every later payment.
- Whenever it happens, we refund the full amount if you were charged twice for the same period, were charged for a renewal after you had cancelled, or paid for a plan that was not activated on your account and we did not put it right within three working days of you telling us.
How to ask for a refund
- Paid in US dollars or another currency other than rupees (through Paddle): ask Paddle at paddle.net, using the email address on your receipt, or reply to the Paddle receipt.
- Paid in Indian rupees or by card through Stripe: write to tech@kannamwar.com from the email address on your account, with the date and amount of the payment and the payment ID shown on your receipt.
We reply within two working days. An approved refund is paid back to the same card, UPI account, bank account or wallet the payment came from, normally within 5 to 10 working days, depending on your bank. We do not refund in cash or to a different account.
Changes to prices
A price change applies only from your next billing period, and we tell you by email at least 14 days before it does.
