This morning the Pew Internet & American Life project released new data on teen app usage and mobile privacy. The big "takeaway" is that teens care very much about privacy and have taken action against (deleted) mobile apps they feel unnecessarily or gratuitously collect personal information or location data.
Pew says that 78% of teens have a mobile phone (though not all have smartphones) and 23% have tablets. The teen smartphone penetration number is probably 58%, given that's the number of teens who have downloaded mobile apps.
Just over half (51%) "have avoided apps due to privacy concerns" while 26% have uninstalled an app because it was collecting personal data. And 46% of teen mobile users have turned off location tracking features (on their phone or in an app) out of concern for privacy.
Teens are more forgiving of apps that seek location data where there's a logical and clear justification for the information (e.g., maps). Girls are more likely to disable location tracking than boys; 59% of girls vs. 37% of boys have done so.
Separately but still on the theme of privacy, Facebook announced today that it would give more control to Facebook mobile log-in users over what information is shared by third party apps on the Facebook Timeline and News Feed. Here's what the company said today in its announcement:
Although Facebook Login is widely used, we understand people’s concerns about apps posting on their Timeline or to their friends. For the past several months, we’ve been rolling out a new version of Facebook Login on mobile to address these concerns.
With this new update, mobile apps using Facebook Login must now separately ask you for permission to post back to Facebook.
Don’t want to share your music playlist or workout routine with friends? You can choose to skip sharing altogether.
Clearly separating sharing means people can decide whether they only want to use Facebook Login for fast registration without also sharing back to Facebook. If you want to share later, you still can.
This involuntary sharing element was a selling point for publishers and developers but a turn-off to many users. It became a significant barrier for some to using Facebook log-in for third party apps/sites.
By separating sharing from social log-ins Facebook hopes to remove friction for many people who might log in with Facebook but don't today for privacy reasons. I'm in that group.
