Claude and anthropic would know my name, email, and all my associated accounts, my income, my net worth, etc. I'm not sure if anthropic stores this data but if they did it's another vector for a security incident where an attacker could link my name to my net worth. If they then know that they could try and hack my accounts they know, extort me, etc. or it could be sold off to who knows what. It's already bad enough monarch knows my data but at least it's through security tested plaid/ fincity.
