No it's not. For example almost everyone has curtains. Do you think everyone that closes their curtains is deceiving someone? Of course not. There are many reasons to keep something private, one of them beeing deception. But it's far from the only one.

"Of course not" because probably nobody is interested in looking in.

That seems like a trivial point to me, though.

As soon as somebody nosy is interested, then there is a purpose of deception.

No it isn't the purpose doesn't change depending on external factors. The purpose is privacy, that is not deception.
