Appclicks is the service we use for tracking anonymous system profile information. When invoking the Retrospect Console the first time you can opt-in or opt-out to "Help improve Retrospect". You can also change your opt preferences at any time in Preferences > Console. When enabled, Retrospect tracks anonymous information such as version of OS, # and types (but not contents) of media sets, etc. When disabled, Retrospect sends an opt-out event to Appclicks and then stops tracking.
