Many apps
send personal data without awareness of the user. The Wall Street Journal (WSJ) studied 101 popular apps and
discovered that 56 of these apps send the unique identification number of the
phone to companies. And 47 of these apps share the location of the smart phones
with others.
Some apps go
even further and sent information about age, gender and other personal details
of the user to different companies. A striking result of the research is that
iPhone apps seem to send more information than Android apps. It is not exactly
clear why.
