Is this how the owner of the account gets information off my phone

[Android Central Question]

My boyfriend is the owner of this account so, is this how he knows who I call or who calls me

Um.. Usually the owner can access all info. What account do you mean? An account on this site for example would only let him access what you do in this site.
If you share a phone company account, then he can see any history.
You are always best to have your own account and not synch any accounts with anyone, it avoids complications if you split up!
