Short description: Smartphone that routes internet connections through the Tor network

A Tor Phone refers to the concept of a smartphone that routes internet connections through the Tor network. The first Tor Phone was a prototype smartphone released in 2016 by The Tor Project, which gave users the ability to route internet connections through Tor for anonymity. Work on Tor Phone was launched in 2014,[1] and a "Tor-enabled Android phone prototype" was announced in 2016.[2] The project was led by Mike Perry, Tor Browser lead developer.[3]

Background

Tor Phone refers to a smartphone set to route internet connections through Tor network, for example using the Orbot application and Android VPN settings,[4] although according to developer Mike Perry in 2016, Android's VPN APIs were not secure and could leak data at boot, which affects Orbot too.[5] The prototype Tor Phone was based on CopperheadOS, which added additional security features.[6][7][8][9] Another option is to use Torbrowser on smartphones.[10][11][12] Follow-on project, GrapheneOS supports using Orbot (Tor) VPN, but not Tor browser, on Android-based phones.[13][14] As of February 2022 or earlier, Orbot is also available for iOS phones.[15]

Adoption

The number of Tor users on phones is unknown. As of 2016 there were about 2 million daily Tor users, total, including all devices and methods.[16]

In 2018 Louis Adam of ZDNet France discussed new official support of Tor Project for Tor services on Android phones, including Tor Browser and Orbot.[10]

John Corpuz of Toms Guide listed Tor Browser (Desktop and Android), and Onion Browser (iOS) as two of 16 "best ad blockers in 2021".[17]

Using Tor with Orbot and Tor Browser are supported by custom Android operating systems CalyxOS[18][19] and DivestOS.[20]

Related projects

In January 2015 David Briggs and Nick Spriggs began an unsuccessful Indiegogo campaign to make the BOSS phone, an Android-based phone with "rooted Tor encryption" to anonymize and privatize internet browsing.[21][22]

In 2014 Blackphone from Silent Circle was sold as an Android-based phone with applications and services to provide more secure messaging, VPN and cloud storage.[23] In 2014 the Boeing Black phone was advertised as a more secure Android-based phone, with dual SIM for using public and government networks.[24][25]

In 2014 a mobile version of TAILS operating system was announced.[26][27]

In 2012 the Ninja phone, an HTC One V phone running Android 4.0.3, was developed to demonstrate using an independent GSM phone network at DefCon. The network was operated from The Ninja Tel van, with official looking logo, a GSM base station; a 12-foot antenna; networking and Web app servers parked in a large room at Defcon.[28]
