From what you buy online, to how you remember tasks, to monitoring your front door, Amazon is seemingly everywhere. And it doesn’t seem like he wants to curb his reach anytime soon. In recent weeks, announced that he will invest billions of dollars in two giant acquisitions that, if approved, will expand it’s growing presence in the lives of consumers. This time, it is targeting two areas: health care, through the acquisition of the primary care company One Medical for 3.9 billion, and home automation, where it plans to expand its already significant presence with a 1.7 billion merger with iRobot, the maker of the popular Roomba robotic vacuum cleaner.

Not surprisingly with a company known for its vast collection of consumer information, both mergers have raised privacy concerns about how Amazon obtains the data and what it does with it. The latest line of Roomba, for example, uses sensors to map and remember the floor plan of a house. “It’s acquiring the vast array of data that Roomba collects about people’s homes,” said Ron Knox, an Amazon critic who works for the Institute for Local Self-Reliance antitrust group.

Other products that you sell to consumers, it’s home  on top of the privacy issues there are the antitrust issues, because you’re buying market share.” Amazon’s reach goes much further. Some estimates show that the retail giant controls nearly 38 percent of the US e-commerce market, allowing it to collect granular data on the shopping preferences of millions of Americans and more around the world.

Meanwhile, its Echo devices, equipped with the Alexa voice assistant, have dominated the US smart speaker market, accounting for about 70 percent of sales, according to estimates from Consumer Intelligence Research Partners. Ring, which was acquired by Amazon in 2018 for $1 billion, monitors doorsteps and helps police prosecute crime, even when users don’t realize it.

And in select Amazon and Whole Foods stores, the company is testing palm-scanning technology that lets consumers pay for items by storing biometric data in the cloud, prompting concerns about the risks of a data breach, something that Amazon has tried to dispel. “We treat the palm signature like any other highly sensitive personal data and keep it safe using the best technical and physical security controls,” the company said on a website that provides information about the technology.

Even consumers Those actively avoiding Amazon have little to say about the way their employers nurture their computer networks, which Amazon, along with Google, has for years dominated through its AWS cloud computing service. another organization that has as many touchpoints as Amazon has with an individual,” said Ian Greenblatt, director of technology research at data analytics and consumer research firm J.D. Power. “It’s almost overwhelming, and it’s hard to admit.” And Amazon’s goal, like any company’s, is to grow. In recent years, it has acquired Wi-Fi startup Eero and partnered with construction company Lennar. to deliver tech homes. With iRobot, you’d get one more piece of the ultimate smart home and, of course, more data. Customers can opt out of having their iRobot devices store the floor plan of their home, according to the vacuum manufacturer.

Data privacy advocates are concerned that the merger is another way Amazon can obtain data to embed in its other devices or use to serve personalized ads to consumers, Amazon spokeswoman Lisa Levandowski said in a statement. let that be the firm’s goal.”We do not use the home maps for targeted advertising and have no plans to do so,” Levandowski said.

Whether that will ease concerns is another question, especially in light of investigations into other Amazon devices. Earlier this year, a group of university researchers published a report that concluded that voice data from Echo devices was being used to deliver personalized ads to consumers, something the company had denied in the past.
