No logs: to protect our users, we do not require registration or login or any personal information to use Ultrasurf, and we do not keep access logs.

Kill Switch: application level Kill Switch is always on for Ultrasurf VPN 2.2.9 or later. In case Ultrasurf VPN connection is lost, no internet connection will be available to avoid potential leaks, unless the user manually switch off Ultrasurf VPN. In case Ultrasurf VPN is killed or Android system VPN is turned off, internet connection will resume. To prevent that, for Android 7 or later, you can enable system level kill switch by going to Settings -> Connections -> VPN, under Ultrasurf, turn on both Always-on VPN and Block connections without VPN).
