LOstorm is a privacy enhanced version of the Firestorm Second Life Viewer designed to prevent LL from identifying alternative accounts, and bypass the login error "Second Life cannot be accessed from this computer".
LOstorm can only help prevent linking accounts via hardware identification. It is your own responsibility to use a VPN and prevent linking accounts via IP address, browser cookies, e-mail address, or payment information!

LOstorm connects to and downloads XML files from phoenixviewer.com for blocked version checks and other FS-specific features. LOstorm may also connect to other third-parties for the purpose of retrieving news to display on the login page: e.g. gitlab.com.
LOstorm also connects to a private server for the purpose of recording the following metrics: IP address (to track daily user counts -- retained for 24 hours), date/time, viewer version, viewer skin, and operating system.
