Tor on Android
Tor is available for Android by installing our package named Orbot.
Orbot is an application that allows mobile phone users to access the web, instant messaging and email without being monitored or blocked by their mobile internet service provider. Orbot brings the features and functionality of Tor to the Android mobile operating system.
Orbot contains Tor, libevent and privoxy. Orbot provides a local HTTP proxy and the standard SOCKS4A/SOCKS5 proxy interfaces into the Tor network. Orbot has the ability to transparently torify all of the TCP traffic on your Android device when it has the correct permissions and system libraries.
