Status: the FDD for Windows installer is being set up for free code signing. Until that is approved, the installer is not signed and Windows may show a "Windows protected your PC" notice (choose "More info" then "Run anyway"). This page describes how signing will work.
Free code signing provided by SignPath.io, certificate by SignPath Foundation.
Only the Windows installer and program of FDD for Windows (the vNAAATS app), built from the public source code at github.com/garythms/vatsim-NAAATS-v2 (folder launcher) by the automated GitHub build. Nothing else is signed, and nothing from other projects is signed under this policy.
Every signing request is approved by hand, and two-factor sign-in is required for the source repository and for SignPath.
This program will not transfer any information to other networking systems unless specifically requested by the user or the person installing or operating it. What the app and website do with data is described on the privacy and data handling page.
