Allowing User Fields to be pesonalized

I would like to pass a user profile variable (ex. Job Title) to an analytics tool. The issue I'm facing is that the user profile variables are cached so the user profile variables are passed are always for the user that cached the page (rather than subsequent visitors).

The solution I've pursued is to enable the authcache_user module and try to pass the desired user profile fields (in hopes of eventually passing these on to the analytics tool):

.module file

function mymodule_init() {
authcache_p13n_add_setting(array('#setting' => 'user'));
drupal_add_js(drupal_get_path('module', 'mymodule') . '/mymodule.js');
}

I'm then simply printing these with JS (for now) to verify the uncached data is visible:

(function ($) {
  Drupal.behaviors.mymodule = {
    attach: function (context, settings) {
      if (settings.authcacheUser) {
console.log(settings.authcacheUser.name);
console.log(settings.authcacheUser.uid);
      }
    }
  };
}(jQuery));

The issue I'm facing is that I can only view the uid, name and email. I'm stumped on how I would I go about adding other user profile variables such as custom fields? Any help would be appreciated...Thanks!
