Is INDMoney app safe?

Is indmoney app safe? Is INDMoney app safe and if I invest in indmoney app in any ETF of US stock can I withdraw it in the same day,can I do it infinite amount of time and what is the charge for withdrawing each time.I am not talking about intraday trading option in that app,I want to know about the investment option as I can buy and sell at any time without any worries.So I want to know even if I buy stocks in the investment option can I sell it in the same day or not?
