Two places, same effect:

• On the web — sign in, open your account page, and choose Cancel.
• In the app — Settings → Account, then cancel your plan.

No email required, no retention call, no form. If either route fails, email hello@wynstack.com and we will cancel it for you.

• Your plan stays active until the end of the period you have already paid for. You do not lose access the moment you cancel.
• The recurring mandate stops. You are not charged again.
• At the end of that period your account moves to the Free plan.
• Nothing you created is deleted. Your calculations, invoices, printers and filament stay exactly as they are.
• If you have more catalog products than the Free plan allows, they are kept but your public catalog shows only the oldest ones up to the Free cap. Resubscribe and the rest reappear.

Because access continues to the end of the period you paid for, we do not normally refund the unused part of a billing period — you keep the service you bought. That said, we would rather refund an unhappy customer than argue with one. We will refund in full when:

• You were charged twice for the same period, or charged after cancelling.
• A payment succeeded but your plan was never activated, and we cannot activate it.
• You subscribed by mistake and tell us within 7 days, having made no meaningful use of the paid tier.
• The service was unusable for a material part of your billing period because of a fault on our side.
• We discontinue the service or a plan you had prepaid for — we refund the unused portion without being asked.

Outside these cases we consider requests on their facts. Ask; a reasonable request gets a reasonable answer.

Email hello@wynstack.com with the Google account you subscribed with and the Razorpay payment id (it is on the receipt Razorpay emailed you). That is enough for us to find the charge.

• We acknowledge within 2 working days.
• An approved refund is submitted to Razorpay within 5 working days.
• The money reaches your original payment method in a further 5–7 working days, depending on your bank. Refunds always go back to the method that paid — we cannot redirect them elsewhere.

If a recurring charge fails, Razorpay may retry it. If it keeps failing, your plan lapses to Free at the end of the paid period and nothing further is taken. If you see a 3DCalci charge you do not recognise, email us before raising a chargeback — we can usually identify and reverse it faster than your bank can.

3DCalci is software delivered over the internet, on a subscription. There is no physical product, no delivery, and therefore no shipping policy and no shipping charges. Access to a paid plan is granted as soon as your payment is confirmed — usually within seconds, occasionally a minute or two while your bank confirms the mandate.

The Free plan requires no payment at all and is available immediately on signing in with Google.
