How Easily Can Different Devices Be Used to Track Someone?

The biggest distinction is between devices that actively communicate and devices that simply contain electronics. Phones, smart TVs, computers, vehicles, and connected appliances can create logs or transmit data. A normal person usually cannot monitor all of that directly, but companies, authorities, and data brokers may have access to different pieces of the information. Whether anyone actually examines it usually depends on the incentive and the specific situation.

It depends heavily on who “they” are and what kind of tracking you mean. A phone can provide location data, internet providers keep connection records, and connected devices may send usage information back to their manufacturers. Some of that data can also end up with advertising or data-broker companies. Governments and investigators may be able to obtain records through legal processes, while ordinary people usually have much more limited capabilities.

Not every electronic device can be tracked. If something has no GPS, internet connection, Bluetooth, cellular radio, or other wireless communication, it generally cannot report its location by itself. An offline washing machine, for example, is very different from an internet-connected smart appliance. However, nearby radio readers, tracking tags, payment-card systems, or specialized equipment can sometimes identify devices without traditional GPS.
