The Nature of Phone Data Collection
Before diving into opt-outs, it’s essential to understand what “phone data” entails:

Location data from GPS, Wi-Fi, and cell towers.

Metadata from calls, texts, and app usage.

Device identifiers such as IMEI numbers, MAC addresses, and advertising IDs.

App data, including browsing history, contacts, calendar events, and messages.

Sensor data from accelerometers, microphones, and cameras.

This data is collected by various actors—device manufacturers, mobile OS providers, app developers, telecom operators, and third-party SDKs (Software Development Kits). Once collected, it can be sold, aggregated, analyzed, or used for targeted advertising and surveillance.
