I am far from a lawyer, so would someone with a better understanding of the law explain to me why this wouldn't potentially violate laws around trade secrets?

I am far from a lawyer, so would someone with a better understanding of the law explain to me why this wouldn't potentially violate laws around trade secrets? If someone uses a 'personal' email for setting up their business' trello account (including what could be categorized as trade secrets); and at some point in the future, they added a different companies domain to their account as a secondary login; and then Trello hands everything over to that other company; how isn't that a violation of trade secrets?
