Google tracks your movements, like it or not

Tech Giant Claims It Gives Clear Description About Its Tools And How To Turn Them Off
San Francisco:  TOI 14.08.2018

Google wants to know where you go so badly that it records your movements even when you explicitly tell it not to. An Associated Press investigation found that many Google services on Android devices and iPhones store your location data even if you’ve used a privacy setting that says it will prevent Google from doing so. Computer-science researchers at Princeton confirmed these findings at AP’s request.

For the most part, Google is upfront about asking permission to use your location information. An app like Google Maps will remind you to allow access to location if you use it for navigating. If you agree to let it record your location over time, Google Maps will display that history for you in a “timeline” that maps out your daily movements.

Storing your minute-byminute travels carries privacy risks and has been used by police to determine the location of suspects — such as a warrant that police in Raleigh, North Carolina, served on Google last year to find devices near a murder scene. So the company will let you “pause” a setting called Location History.

Google says that will prevent the company from remembering where you’ve been. Google’s support page on the subject states: “You can turn off Location History at any time. With Location History off, the places you go are no longer stored.” That isn’t true. Even with Location History paused, some Google apps automatically store time-stamped location data without asking.

For example, Google stores a snapshot of where you are when you merely open its Maps app. Automatic daily weather updates on Android phones pinpoint roughly where you are. And some searches that have nothing to do with location, like “chocolate chip cookies”, or “kids science kits”, pinpoint your precise latitude and longitude and save it to your Google account.

The AP learned of the issue from K Shankari, a graduate researcher at UC Berkeley who studies the commuting patterns of volunteers in order to help urban planners. She noticed that her Android phone prompted her to rate a shopping trip to Kohl’s, even though she had turned Location History off. “So how did Google Maps know where I was?” she asked in a blog post .

The privacy issue affects some two billion users of devices that run Google’s Android operating software and hundreds of millions of worldwide iPhone users who rely on Google for maps or search.

Storing location data in violation of a user’s preferences is wrong, said Jonathan Mayer, a Princeton computer scientist and former chief technologist for the Federal Communications Commission’s enforcement bureau. “If you’re going to allow users to turn off something called ‘Location History’, then all the places where you maintain location history should be turned off,” Mayer said.

Google says it is being perfectly clear. “There are a number of different ways that Google may use location to improve people’s experience, including: Location History, Web and App Activity, and through device-level Location Services,” a Google spokesperson said in a statement.

“We provide clear descriptions of these tools, and robust controls so people can turn them on or off, and delete their histories at any time.” To stop Google from saving these location markers, the company says, users can turn off another setting, one that does not specifically reference location information. Called “Web and App Activity” and enabled by default, that setting stores a variety of information from Google apps and websites to your Google account.

While disabling “Web & App Activity” will stop Google from storing location markers, it also prevents Google from storing information generated by searches and other activity. That can limit the effectiveness of the Google Assistant, the firm’s digital concierge.

Critics say Google’s insistence on tracking its users’ locations stems from its drive to boost advertising revenue. “They build advertising information out of data,” said Peter Lenz, the senior geospatial analyst at Dstillery, a rival advertising technology company. “More data for them presumably means more profit.” Since 2014, Google has let advertisers track the effectiveness of online ads at driving foot traffic , a feature that Google has said relies on user location histories. The company is pushing further into such location-aware tracking to drive ad revenue, which rose 20% last year to $95.4 billion. AP
