I know that I should not reveal the names of members that I hear in A.A. meetings, but what about other personal information?

It is understood by A.A. members that personal disclosures made in A.A. meetings are to be treated as confidential. For example, if friends outside the program are acquainted with some of your A.A. friends and know of their membership, you should be careful not to violate confidences picked up at meetings, however harmless they may appear at the time.
