Is Bitbuy a wallet?

I'm curious about Bitbuy, as I've heard it mentioned in some cryptocurrency circles. But I'm not quite sure what it is. Could you clarify for me if Bitbuy is considered a wallet? I've seen people talk about using it to store and trade cryptocurrencies, but I'm not entirely sure if it functions like a traditional wallet where I can store my private keys and manage my coins securely. It would be helpful if you could explain the functionalities of Bitbuy and how it differs from, say, a hardware wallet or a software wallet. I'm just trying to get a better understanding of this platform before I decide to use it for my crypto needs.
