gaoo.js

Simple Google Analytics Opt-Out helper.

gaoo.js is a small helper script to opt-out from Google Analytics Tracking.

It uses local storage to remember an opt-out and will set a window property which Google Analytics inspects to decide whether to track or not. It supports DNT and respects it by default, if not configured otherwise.

Usage

// Initialize on page load with respect to DNT.
window.gaoo('UA-123456-1');

// ... initialize on page load and do not respect DNT.
window.gaoo('UA-123456-1', false);

// Actively opt-out from Google Analytics tracking.
window.gaoo('UA-123456-1').enable();

// Actively opt-in to Google Analytics tracking, again.
window.gaoo('UA-123456-1').disable();

// Check if currently opted out.
if(window.gaoo('UA-123456-1').check()) {
  window.console.info('Currently opted out.');
} else {
  window.console.info('Tracking page-view now.');
}

// Get opt-out identification string.
var identifier = window.gaoo('UA-123456-1').identifier;

// Get DNT browser setting.
window.console.log(window.gaoo('UA-123456-1').dnt()); // true or false
