As it stands, there
is currently no way to find out who has viewed your profile in
whatsapp. The developers of the app appear to be concerned with
protecting it's users privacy- recently introducing measures which
allow users to hide their “last seen” time and date, status and
profile pictures to allow them to use the app without having to
reveal to anyone that they are online.
Given this, it seems
unlikely that they will develop a feature which allows users to track
the activity of people viewing their account.
That said- there are
some unofficial apps around which give you an insight into your
Whatsapp usage- who has sent you the most messages, who usually
starts the conversation and similar kind of statistics- but as with
most unofficial apps, these are not all that reliable. WhatStat for
Android which provided this sort of information, appears to have been
disabled with recent updates to Whatsapp, and no longer seems to
work.
