I usually try to remember to tuck them out of sight, as I usually have a stream of students popping by, neighbours curious to see how the foreigner lives, school teachers, student parents... which I do not encourage.
But... I do not always remember... ahhh the joys of living by oneself!! and there have been more than one occasion where my "company" decided to snoop and press buttons then squeal in horror and return to the room, or sit up red faced when the light bulb clicks on that it is a sex toy.
When I visit my family in North America, night stand drawer if I get my own room, or in my suit case if I am on the move. And yes, I've had to speak to my family about going through my things. Much to their red faces.
