Hi. Thanks for the question.
I can understand your concern. Unlike the true God, Satan is a created being with certain limitations of all such. He is a particular being in a particular place. God's Word never ascribes everywhere present, all knowing kinds of attributes to him. Honestly, Satan probably doesn't even know you exist. Unless you are a major force in shaping the opinions of the world, he has bigger fish to fry. He accomplishes his goals by executing his authority as commander in chief over lesser devil spirits. Certain of these might know you exist, but, no, they cannot read your mind.
Bless, Ken Brown
