AutoKbSwitch makes no network connection of its own (the link in Help → About just opens the project page in your browser), never reads other programs' memory and injects nothing. It only writes %APPDATA%\AutoKbSwitch\config.json and, if the option is enabled, the AutoKbSwitch value under HKCU\Software\Microsoft\Windows\CurrentVersion\Run.
