What a system policy means in practice
A policy is a decision you set once so you do not have to decide under pressure later. On phones, policies
commonly show up as permission choices, notification rules, background behavior, and app-level access.
The safest approach is to review policies in small passes. Change one thing, then use the phone normally.
If the change creates friction, revert it. That is still progress because you learned what matters to you.
Common policy categories
Access policies
Rules for which apps may use device features (location, camera, microphone, notifications).
Attention policies
Rules for how and when apps are allowed to interrupt you with alerts and lock-screen details.
Background policies
Rules for which apps can refresh or run when you are not actively using them.
Install policies
Rules you follow for adding apps: source, necessity, and whether you still want it later.
