Some Android apps send data to Facebook, regardless of whether users have an account on the social network, or not, warns new research.
A study of Privacy International analyzed the data as 34 Android apps, each with between 10 million and 500 million customers, sent to Facebook.
"We found that at least 61 percent of the apps we tested automatically transfer data to Facebook the moment a user opens the app," it said in a statement. "This happens if people have a Facebook account or not, or they are signed in to Facebook or not."

"We also found that some apps routinely send Facebook data that is incredibly detailed and sometimes sensitive," Privacy International added.
Data is shared with tech giant through Facebook's Software Development Kit (SDK), according to the report.
"Usually, the data that is automatically transferred first is event data that communicates to Facebook that the Facebook SDK has been initialized by transferring data such as" App Installed "and" SDK Initialized "," says Privacy International. "This data reveals the fact that a user uses a particular app each time this user opens an app."
