Is it ethical to lie in order to protect one's privacy? What about someone else's privacy?

Please assume that their is nothing in the person's privacy that involves having done spoil to anyone. This is a Q about the right to privacy not about hiding anything bad in the region of oneself or about others. It is an ethics Q and I'm looking for ethical reasons for such lying, if it exists.
I am not clear of your premis. If you mean similar to opening an email account with false information, to be exact not lying but protecting one's privacy. It would, however, be lying if you were using the servce under some false pretense such as stating that all the information you provided is true.

The ethical response is to state that you junk to discuss it in order to protect the privacy of those involved.

Lying is not ethical.
From the utmost rhelms of government to the toddler at home...there are "lies" from which we can say are "wrong" but not necessarily wrong.

You don't report to your spouse they've gained twenty pounds and look bad. You tell them they "look fine."

You don't speak about a child "there isn't a Santa Claus" until they're old enough to become conscious what gift giving is all about.

You hear our system state "We decline to acknowledge or deny...." (which is not necessarily lying but not being forthright) an issue because knowing the "truth" could cause harm to the collateral of a nation!

Is there "ethical lying" in our world....I think so!
lying have its strange ways of being ethical
on one side u saved urself and ur friend
on the other side u just hurt someone else
to be exact not the definition of ethical
ethical-pertaining to or dealing with morals or the principles of morality; pertaining to right and wrong in conduct.
lying has no morals
