First of all, I would like to say that at first I thought it was just some kind of usual HOAX and didn't care too much about it. However, as more and more articles came out, I did some research on the app.
And I have to say that I do not want it. First of all, I really do not like the way it got onto my phone... without asking, even without notification. Definitely a subjective thing, but I hate the behaviour of the process, doing things with my device without asking me.
So. Google doesn't give much information, and even the official Play Store page for this app is... strange? Bizarre? It definitely does not look serious, even though it is made by Google.
The app is said to provide some kind of "mystical" added security, but reverse engineering shows that it scans outgoing and incoming communications and, among other things, sometimes filters "explicit content". First of all, I don't need someone telling me what to see and what not to see, and for the second part, the detection of these things is definitely not done locally, and I don't need another channel that spoils my personal data.
So I delete it for now. And maybe if there is more information about what it is and what it does, then I will think about installing it again, but I might not.
