Grant the smallest access that still lets the selected feature work.

Core ideas

Use these points to build an accurate technical model before changing the device.

  • Ask whether the permission is needed for the whole app or one optional feature.
  • Prefer approximate location, selected photos and one-time access when available.
  • Revisit permissions after updates and after you stop using a feature.

Decision rule

A permission can be legitimate and still unnecessary for your personal workflow.

Apply it on your phone

Record the device facts, source and expected result. Make one reversible change, observe the outcome, and keep the evidence needed to undo it.
