Privacy and Data Management on Mobile Devices: Summary of Pew Research Center 2012 Report

Key Findings

• Smartphone users are more active in managing data (e.g., backing up, clearing history, turning off location tracking), but face higher risks of privacy invasions.
• Demographics such as age, gender, and education influence behaviors but do not significantly alter the proportion of users avoiding or uninstalling apps for privacy.
• Key statistics:
  • 54% of app users avoid apps upon discovering needed data sharing.
  • 30% of app users uninstall apps after learning about data collection.
  • Smartphone users back up their phones more often than basic phone users (59% vs. 41%).
• Physical risks: About 31% of cell owners experience lost or stolen phones, and 12% report privacy invasions.
