Also the funds are always stored in your wallet we do not handle any funds everything is decentralized.
How is it decentralized? It is not.
Is it not an instant exchange? A buyer or seller will send coin from there wallet to the address you will provide them which is under your control. For reputed instant exchanges, the coins can be freezed, but for new instant exchange like yours, the coin can be stolen by you. All centralized on the instant exchange owner.
It is not decentralized at all, you have the control once anyone send coin to the address provided, a means to freeze or steal the coin and the reason it is centralized.
