Your Data Trail

Install an app one permission at a time and keep your data trail as small as possible.

Your Data Trail

You are installing a free Flashlight app. It asks for one permission at a time. Allow only what a flashlight truly needs โ€” every extra โ€œAllowโ€ adds to your data trail.

Permission 1 of 7

โ€œFlashlight would like to Use the camera's flash โ€” the bright LED light.โ€

How does it actually work?

Every permission you grant lets an app collect a piece of data about you. Together those pieces form your data trail โ€” and once data leaves your device, you rarely control where it goes next.

The defence is data minimisation: share only what a tool genuinely needs to do its job. A real test of whether a request is honest is to ask, โ€œDoes this app actually need this to work?โ€ 3 of these 7 requests passed that test โ€” the rest did not. Owning your data starts with not giving it away by reflex.
