Extends the GoogleAnalyticsTracker Vaadin Add-On by additional features for privacy protection. In some countries these features are required for legal usage of GoogleAnalytics.

(1) IP Anonymization Enables the "AnonymizeIP" parameter in the GA tracking. Can be disabled by setAnonymizeIp(false). If AnonymizeIP is enabled Google doesn't store the complete IP of the user. Check the GoogleAnalytics API documentation for more information about that parameter (see link section). This feature is only available when using the universal tracking mode.

(2) Opt-out support Provides an opt-out option by calling the method addOptOutCookie(). It sets a cookie which disables tracking for the user.

Sample code

// Create a tracker for vaadin.com domain. The Anonymized extension supports the same constructors as the original add-on.
AnonymizedGoogleAnalyticsTracker tracker = new AnonymizedGoogleAnalyticsTracker ("UA-658457-8", "vaadin.com");

// Attach this analytics component to a UI to enable tracking
tracker.extend(UI.getCurrent());

// Track the page view
tracker.trackPageview("/samplecode/googleanalytics");

// Or add the tracker as ViewChangeListener to the navigator to automatically track every view change
UI.getCurrent().getNavigator().addViewChangeListener(tracker);

// Set opt-out cookie to the user's browser to disable tracking
tracker.addOptOutCookie();

// Check if opt-out cookie exists
tracker.isOptOut();

// If you like to switch off the IP anonymization (for whatever reason)
tracker.setAnonymizeIp(false);
