The Telephone with Dial Tone and associated Busy Signal. A busy signal meant nobody could contact me; Also, by either not answering the phone or by simply taking the receiver off the hook I controlled interruptions. And, nobody became concerned if they did not hear from me in an hour, 1/2 day, day or even week. And I had no concern if I did not hear from others either in that timeframe.
So the "tool" to maintain privacy was very controllable by me and nobody would think otherwise.
