Amazon's Alexa Collects More of Your Data Than Any Other Smart Assistant

From PC Mag: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 showed that 56% of respondents are concerned over data collection. After analyzing the terms and conditions of Alexa, Google Assistant, Siri, Bixby, and Cortana, though, it was clear that some degree of data collection is ultimately inescapable.

In the survey, 60% of respondents were concerned about someone listening to their voice recordings, which is a real fear, since Google and Apple have both been caught doing just that.

(It's probably not a coincidence that our readers recently named Alexa to be the least trustworthy voice assistant.) Samsung's Bixby collected 34 points of data, and Cortana collects 32 data points. Meanwhile, Siri collects just 30, and Google's smart assistant takes only 28, making them the least invasive.
