How checkout actually works
Payments run through Razorpay, not a homegrown billing system. When you hit Upgrade, Klick.ing creates a Razorpay subscription and hands you off to Razorpay's own secure checkout — your card or UPI details are entered there, not on Klick.ing directly.
Once Razorpay confirms the charge, your plan activates automatically. Recurring renewals after that are handled entirely by Razorpay on their end.
