Ultrasurf
What Ultrasurf is
Ultrasurf is a free tool for bypassing internet censorship, encrypting online communications, and hiding an IP address from visited websites. It provides a Windows client, iOS and Android apps, and a Chrome extension. The Windows executable requires no installation: it establishes an encrypted tunnel to Ultrasurf servers and then opens the default browser. The iOS app supports iPhone and iPad applications, while the Android app supports Android mobile applications and is described as beta software requiring Android 4.1 or later. The Chrome extension is installed through the Chrome Store. UltraReach says users need not provide personally identifiable information and that it does not collect it. Its privacy statement says browsing activity and personally identifiable information logs are not collected for the extension and proxy clients, except when optional Safe Browsing is enabled. That feature is off by default and, with consent, sends a page URL and available referrer for unsafe-content checking.
