Secretly gamble?

So my question would be if my dad can see it when I'm gambling. So I'm signed in with his email address (I'm talking about EA and Epic Games). So can he see it when I play fortnite or something? It's his email address, I don't know my way around very well.

He can only see it if you make any in-game purchases or if he has installed the launcher himself and thus sees whether the account is currently active. He can also see it when you link your accounts or something, because you will always receive confirmation emails…

As far as I don't know

Many Thanks

Thanks
