It's tricky for sure, I agree. If I write a letter to a bank, it's certainly theirs to turn over. But if I put a letter to someone else in my safe deposit box at the bank, they can't turn that over without a specific warrant and probable cause.

Google searches are tricky for sure. I'm asking Google to look something up for me. What I looked up is their record.

But for example, video rentals are specifically protected as are library checkout records. Even though I've asked those places to do something for me, they can't reveal that.

So yeah, it's tricky, but at the end of the day it should probably count as my personal property.
