The app has a licence well visible when you install the app. The rest is written in the website and in github. Then about: requires an activation code to use, ofc it is made for ethical research purposes, so yes I am distributing it responsibly. And you can see the videos in the youtube channel for how it works. But the most important point is that you can try it easily with a firewall to see that it do not leak bytes like all the rest there. That´s what i call privacy, It has a button that cut all connection. You can say what you want but that´s it that´s all.
