Is Cashkaro Safe?

Hi Everyone!

I recently came across CashKaro through Reddit. They have cashbacks upward of Rs. 1000 for credit card applications. It sounds too good to be true.

Is it safe? Does it have privacy concerns? Given for a credit card application, we would be sharing personal information like PAN Number, I am very skeptical and don't want to take risk with that. What is the catch here?
