Alexa knows what you look like, as does your Ring camera. And your Samsung Smart Things Hub is probably recording you right now. 

TechShielder looked at what popular smart home devices collect to find out which ones know the most about you. It narrowed the list down to 10: the Amazon Echo Dot, Chromecast with Google TV, Samsung SmartThings Hub, Nest Protect, Ring Indoor Cam, Levoit LV-PUR131S, Sonos One, TP-Link Kasa Smart Plug, Roborock S6, and Philips Hue. 

Nearly all of the devices TechShielder examined collect some basic information, such as your name, address, timezone, phone number, email, IP address, location, information shared with third parties, payment information, and device type.

But lots go beyond that, with voice recording (70%), photo access (50%), video access (50%), user profile images (50%), video (40%), and personal description (40%). They even know you better than your family might when it comes to some things, since they know what you buy (70%), what you look at online (50%), apps you use (40%), all your internet searches (40%), and your personal interests (30%).

Out of the 10 devices, TechShielder found that the Amazon Echo Dot with Clock hoovers up the most data points (43%).

"The Echo Dot stores personal information like our name and address, has access to our photo and video files, and stores live voice recording data," TechShielder said. "This device collects more information about our online activity than all other devices, including data such as browsing history, downloads and web searches.

"It is also one of only three devices (along with the SmartThings Hub and Chromecast) to store information about our contacts, such as their name or phone number," TechShielder added.

TechShielder, however, acknowledged that the volume of data collected by the Echo Dot "makes sense" since it's "one of the most versatile products in the range we researched." Whereas security cameras or smart thermostats are designed to do one thing, "the Echo Dot serves more than one purpose: you can use it to make phone calls, control smart home features like lights and indoor temperature, operate your TV, and more."

Rounding out the top five most data-hungry smart home devices: Chromecast with Google TV (42%), Samsung SmartThingsHub (37%), Nest Protect (34%), and Ring Indoor Cam (26%).

Senior Features Writer

My Experience

My title is Senior Features Writer, which is a license to write about absolutely anything if I can connect it to technology (I can). I’ve been at PCMag since 2011 and have covered the surveillance state, vaccination cards, ghost guns, voting, ISIS, art, fashion, film, design, gender bias, and more. You might have seen me on TV talking about these topics or heard me on your commute home on the radio or a podcast. Or maybe you’ve just seen my Bernie meme

I strive to explain topics that you might come across in the news but not fully understand, such as NFTs and meme stocks. I’ve had the pleasure of talking tech with Jeff Goldblum, Ang Lee, and other celebrities who have brought a different perspective to it. I put great care into writing gift guides and am always touched by the notes I get from people who’ve used them to choose presents that have been well-received. Though I love that I get to write about the tech industry every day, it’s touched by gender, racial, and socioeconomic inequality and I try to bring these topics to light. 

Outside of PCMag, I write fiction, poetry, humor, and essays on culture.

My Areas of Expertise

  • Making incomprehensible tech news easy to understand
  • Expanding the boundaries of topics covered in the industry
  • Figuring out tips and tricks in apps and on devices and letting you know about them
  • Putting together gift guides for everyone in your life 

The Technology I Use

All that gadgets is gold for me: my iPhone 11 Pro, my fifth-generation iPad that I use only for streaming videos and music, my iPad mini 4 that I like to take with me whenever I carry a bag that can fit it, and my MacBook Pro. Why are they all different shades of gold, though? What’s going on, Apple? 

None of them quite live up to my two past loves: my LG Lotus LX600 phone and my Sony Walkman NW-E005 MP3 player. 

I've never given up wired earbuds so I was ahead of all those trend pieces. I use a Mangotek Lightning-to-3.5mm headphone jack adapter to connect them to my phone. 

I have had so many ebook readers, but I prefer paper to them all. Still, my Kindle Paperwhite is perfect for traveling or when I’m too impatient to wait for a book to be released in paperback.
