So the marketing emphasizes the privacy aspects of this device, yet in the comments (not noted on the website), you state that it has "no security whatsoever". This seems like an important disclaimer that should be given on the website.
The website doesn't use HTTPS, includes trackers, and it might be the case that the author hasn't figured it out that without mitigations, wifi can be tracked just like cellular radio.
In short, it's the scammiest looking project I've seen posted to HN in a long time. At least they aren't taking money yet so the author can continue to shoot himself in the foot in comments.
As a side effect of that there are some properties related to security that you get for free (no tracking cookies, no black box cellular radio), and others, like encryption, that we will try to add if we make enough to fund doing it. But we won't feature creep the project and risk never delivering just to check a box that's not part of our core goal.
