Facebook this week told senators that it continues to track the location of its users even after they've said they don't want the social media giant to know where they are — and it makes money off of that information.

The senators had asked Facebook to explain how it learns the location of its users and whether it continues to track that information even when users opt out.

The company's deputy chief privacy officer, Rob Sherman, wrote that Facebook is able to deduce location based on a user's IP address and how they behave on the platform, even if they've turned off "location services" on their phone. For instance, the platform can figure out where a user is located when they consistently say they are attending events in a certain city.

"When location services is off, Facebook may still understand people’s locations using information people share through their activities on Facebook or through IP addresses and other network connections they use," Sherman wrote. 

And, he added, "as part of using Facebook, people may provide Facebook with specific information about their location ... They may check-in at a restaurant or a store, or apply a location tag to a photo, or their friend might tag them in a check-in post." 

Sherman also noted that Facebook always serves ads based on location information, even after a user has chosen to turn off location-tracking from their phone.

"By necessity, virtually all ads on Facebook are targeted based on location, though most commonly ads are targeted to people within a particular city or some larger region," Sherman wrote.

Coons and Hawley on Tuesday both criticized Facebook's response to their letter, panning the company for continuing to make money off of personal information that users have explicitly said they don't want Facebook to have.

Coons, who helps head the Senate Judiciary Committee's tech task force, called Facebook's efforts "insufficient and even misleading." 

"Facebook claims that users are in control of their own privacy, but in reality, users aren’t even given an option to stop Facebook from collecting and monetizing their location information," Coons said. "The American people deserve to know how tech companies use their data, and I will continue working to find solutions to protect Americans’ sensitive information."
