It’s difficult to have useful conversations about mobile tracking when someone says “your phone / mobile device tracks you”; such statements don’t often lead to constructive conversation because they are too vague and therefore easily dismissed as sensationalism or paranoia. And they are all too often without substance because, while users do have legitimate concerns, they aren’t necessarily aware of the specific problems contributing to those concerns.
A mobile device is nothing more than a small computer that you carry around with you. The networks that you connect to can spy on you—your cellular network, bluetooth, wifi, etc. To help mitigate these threats, you can disable those communications until you are in a safe place that you don’t mind others knowing about. We can only have confidence that these connections have been disabled by physical means, like a hardware switch or a bag that acts like a Faraday cage. iOS deceives users when they ask to disable those communications for example.
The software running on your device often spies on you: the operating system itself often spies; the apps you install often spy. This is the fault of the individual authors—they are the problem. Consider using free/libre software that empowers you and serves you rather than its creators; it’s much harder to hide secrets in free software. On Android, consider using only free software available in F-Droid. We also need fully free mobile operating systems, like Replicant and hopefully Purism’s Librem 5 that is still under development. Don’t be fooled into thinking the Android on most phones is free software—only its core (AOSP) is.
Call out those that do harm—don’t veil and protect them using statements like “your phone tracks you”. Talk about the specific issues. Demand change and have the courage to reject them entirely. This involves inconvenience and sacrifice. But if we’re strong now, then in the near future perhaps we won’t have to make any sacrifices, much like the fully free GNU/Linux system desktops we have today.
