What They Know – Mobile

“Marketers are tracking smartphone users through “apps” – games
and other software on their phones. Some apps collect information
including location, unique serial-number-like identifiers for the
phone, and personal details such as age and sex. Apps routinely
send the information to marketing companies that use it to compile
dossiers on phone users. As part of the What They Know
investigative series into data privacy, the Journal analyzed the
data collected and shared by 101 popular apps on iPhone and Android
phones (including the Journal’s own iPhone app). This interactive
database shows the behavior of these apps, and describes what each
app told users about the information it gathered.”
