Google has an opt-out for Google Analytics
To provide website visitors with the ability to prevent their data from being used by Google Analytics, we have developed the Google Analytics opt out browser add-on
Normally you would expect an opt-in for these kind of services, but an opt-out is something. Analytics is a program they run on my device without asking or without consent, taking CPU, battery and bandwidth and probably privacy.
But how do I opt-out on my mobile Android browser?
