Whate are "AnalyticsService" and "CampaignTrackingService" for?

Hi,

someone knows what these two services in Greenify are for (see screenshot). I guess that the "Campaign" stuff should be for the "Raise your voice program" (BTW, "opt-out" insted of "opt-in" is evil), but what's this "Analytics" stuff? Does Greenify gather informations to send them... somwhere?



(they are disabled because " disable them).
