Can my landlord see my wifi history?

Hi all,

So from what I understand it’s clear that if my landlord is the “owner” of my router, they can see my internet activity.

My question is however, to do this, do they have to specifically request a sheet of history? Or is it automatically included in each months bill?

Is there anything that could prevent them from requesting this? Even though their name is in the contract?

My question in short is, how much work is it for …
