About this app

PrivacyGuard inspects the network traffic of all apps on your smartphone in order to detect leakage incidents, where an app sends your personal information across the network.

PrivacyGuard first retrieves your current location, various device identifiers, and the phone numbers and email addresses of your contacts. It then looks for this information in the outgoing network traffic of the apps on your smartphone. It alerts you when an app is found to leak some of this information. You can also choose to ignore particular kinds of leakage.

PrivacyGuard does *not* require root access. It sets up a VPN through which all traffic of your apps is routed. Importantly there is no remote VPN server; all the inspection is done locally on your device. Moreover, PrivacyGuard does not submit any information to remote entities.

PrivacyGuard is open source: https://github.com/cryspuwaterloo/privacyguard. It is based on research from the CrySP research group at the University of Waterloo (https://crysp.uwaterloo.ca).
