Privacy without panic

Real threats deserve precise language.

Commercial spyware, cell-site simulators, device interdiction, data brokerage, and platform telemetry are real. No phone or operating system makes every adversary disappear.

WHAT CHANGES

Reduce specific exposure and gain control.

A different OS can change bundled services, permissions, exploit protections, update sources, and which companies receive routine device data.

WHAT REMAINS

Networks, accounts, apps, and behavior still matter.

Your carrier, the accounts you use, other people, physical access, and targeted attacks remain part of the picture.
