It is a custodial wallet and exchange. The way that it's custodial implies that you're not in charge of your assets. You don't claim the private key to move the assets. Rather it stores those assets for you basically like a bank.
The wallet can store few cryptocurrencies as well as multiple tokens. You can send these to any address or to other in-app users. Move to different users is gratis since they don't include a real transfer of assets on the blockchain.
Generally, It is a decent wallet and a good exchange to sell/trade your cryptocurrencies.
