Hey silentius thanks for your time,

So our app is a similar CONCEPT to QubesOS. The difference is that Qubes is an operating system, while our's is a leaner lightweight environment with an isolated filesystem, 2nd networking stack, and a 2nd graphical display.

So Qubes would be a little better security for running untrusted malicious software, but this comes at a heavy price. Our app does not have the performance speed issues, USB issues, or complexity to setup of Qubes, while giving nearly all of the upside benefit.

BOTH Simplified Privacy and Qubes, protect against keyloggers or shared graphical display security issues. BOTH our app and Qubes, fool websites on screen dimensions. And our app isolates the filesystem to prevent any apps from within it from accessing files outside it.

Plus if you like, you could run our app inside Qubes for the purpose of $1 burner identities and/or evading Tor blocks. The primary purpose of our app is to fool browser fingerprinting, and the solid security isolation is a bonus as well.
