Is Atomic Wallet hot or cold?

I'm curious, can you clarify for me if Atomic Wallet falls into the category of a hot wallet or a cold wallet? I've heard different opinions on this matter and I'm trying to get a clear understanding. Hot wallets, as I understand, are connected to the internet and thus more susceptible to hacking and theft, while cold wallets are offline and considered more secure. So, which one is Atomic Wallet? Is it a convenient online option or a safer offline storage solution? I'd really appreciate it if you could enlighten me on this matter.
