I think I should be able to completely cut it off from the network and/or local storage; prevent it from running even though it is installed; and prevent it from having any personalizing information about me, my movements, my network connectivity status or patterns, my device usage (i.e. screen on versus locked, any proxy like battery state of charge), etc.

I am very reluctant to install apps because I see that the platform is designed for needs and a mindset that is not my own. I do not see it as essential or preferable that an app be able to monetize my usage or really gather any telemetry at all.
