Our smart devices are listening. Whether it's personally identifiable information, location data, voice recordings, or shopping habits, our smart assistants know far more than we realize.

A survey on smart assistant usage conducted by Reviews.org showed that 56% of respondents are concerned about data collection. After analyzing the terms and conditions of Alexa, Google Assistant, Siri, Bixby, and Cortana, though, it's clear that some degree of data collection is inescapable.
