Smartphones are considered by many to be a greater privacy risk than desktop computers due to their constant physical presence, extensive built-in sensors, aggressive app-based tracking, and a more restricted software ecosystem. While both devices face cybersecurity threats, the nature of smartphones makes them a uniquely powerful data collection and tracking tool.
Ubiquitous data collection
Constant sensors. Your smartphone is a bundle of sensors that tracks your location, motion, and environment. Apps can access GPS, Wi-Fi networks, Bluetooth, accelerometers, and microphones, often creating a detailed map of your movements and habits. A desktop PC, by contrast, is a stationary device with far fewer ambient data-gathering features.
Always-on nature. Unlike a PC that is shut down or left in a static location, a smartphone is on and with you almost all the time. This creates a continuous stream of data for apps and advertisers, even when you aren't actively using them.
Unique identifier. Smartphones are inherently associated with a phone number and a cellular subscriber account. This creates a direct link to your real identity that is not present on a desktop PC, making it easier for apps and data brokers to identify and track you.
