Unfortunately, heaps of useful and practical apps are some of the most serious threats to your own data security.
Take GasBuddy, for example. It's meant to help you save precious cash at the pump by letting you compare prices at gas stations nearby—wherever you are—but that also means it's gathering loads and loads of location data to make those calls.
Sure, just the gas station location data could be used to triage locations like where you work, live, and go out, but explicitly collecting data on your whereabouts in the background all the time feels like a full-on manifestation of Big Brother.
Imagine if GasBuddy experienced a data breach. Do you want a hacker to have information about where you live?
