This may be a dumb question, but it's been on the back of mind while working through getting comfortable with GrapheneOS and some hardened Firefox changes.
Is there a way to quantify or confirm your security changes as it relates to GrapheneOS? Say you delete Facebook app from your phone completely, how do you quantify that this change has done anything? How do you audit and continually improve your security posture?
I would assume that a lot of this comes from understanding the trackers and other data collected by specific apps. Is there a definitive list that describes what each app does or doesn't do?
Appreciate the community!
