Some research on Google/Android data collection


If you are interested in how much your Android phone talks to Google, there is a new study out from a CS guy at Vanderbilt. Some of the key takeaways are posted at:

You can, if you have lots of reading time, download the entire 55 page study as a PDF from the URL above. Not unexpected, but interesting to see the quantity of data collection events. The data below refers to phones sitting idle with the screen blank.

A dormant, stationary Android phone (with the Chrome browser active in the background) communicated location information to Google 340 times during a 24-hour period, or at an average of 14 data communications per hour. In fact, location information constituted 35 percent of all the data samples sent to Google.

… an idle Android phone running the Chrome browser sends back to Google nearly fifty times as many data requests per hour as an idle iOS phone running Safari.
