BuddyPress.org

you can’t really hid the entire profile out of the box but you can hide most of the fields and info by setting the default visibility in the profile field setup screens.

@mossyoak How did you accomplish that?

I need a solution that allows only the user (and the admin) to see their own profile. I need it so members not involved (@mentioned) in conversations on activity strea cannot see them.

Only the members involved and the admin should be able to see the conversation.

Thanks,

I mis-read your question sorry. I found a solution which lets users only view other users profiles if they are a friend of that user. The admin can see all members regardless of them being his/her friend.

I put the function in my functions.php:

 // BuddyPress create conditional if friend
function flatportal_bp_is_friend() {
global $bp;

if (friends_check_friendship( bp_loggedin_user_id(), bp_displayed_user_id() )  )
return true;

return false;
}

and created a custom header file with this at the top:

// Global $bp variable holds all of our info

global $bp;
// The user ID of the currently logged in user
$current_user_id = (int) trim($bp->loggedin_user->id);
// The author that we are currently viewing
$author_id  = (int) trim($bp->displayed_user->id);
if ($current_user_id !== $author_id && !current_user_can('delete_others_pages') && !flatportal_bp_is_friend() )
{
wp_redirect( home_url() );
exit();
}

Then in header php (using multiple headers)

elseif ( bp_is_user()):
get_header('restrict-profile');

If they are not a friend they will be redirected to the home page or wherever you want them. I suppose you could re-direct them to a “you are not a friend of this user” page if you wanted.
