Q:

A Russian translation for "privacy"

How would you translate privacy into Russian?

May I have some privacy?
I care about my privacy.

A:

I think we have a case of a concept not really present in the Russian linguistic world image. One can speculate if the privacy has not really been valued until recently, but that's beyond the point.

Конфиденциальность can be used in more formal cases, like in the terms of use of a website, for example. It refers to the information collected about a person (think Facebook).
Частная жизнь (as in неприкосновенность частной жизни) is again a law-term, usually referring to the actual physical privacy.
For colloquial usage, what @Dima suggests is probably the best solution. 

A:

AFIK, there is no good translation. Lately, I have been encountering the word приватность, but I don't think it is standard.
If you have to translate it, you have to reword it taking the context into account.  For example, you might translate Can you give us some privacy? as Не могли бы вы оставить нас одних?  Or you might translate I value my privacy. as Я не люблю когда лезут в мои дела.

A:

I would guess:

конфиденциальность
частная жизнь
неприкосновенность частной жизни
секретность
уединенность, уединение
тайна
личное дело
интимная сторона личной жизни
интимная сфера
прайвеси
