They hide who they are. If you look at their privacy policy:

Then you'll notice that it does not tell you what entity they are or where it is incorporated.
Elsewhere they claim to be incorporated as Trusted Solutions Ltd in Mahé in the Seychelles.

And this review claims they are an LLC.

But when I search for this name in the local registry I get no results.

The Seychelles kind of belong to the 'non-aligned' group of countries, and maintains decent relations with Russia, India, China and so on. They also advocate for a diminished US presence in the Indian Ocean. On the other hand, they're a member of the british Commonwealth and only got independence in 1976.
Trust.Zone sure looks fishy but I can't tell from this whether they are surveillance for the UK, traffic to hide in for russian authorities and cyber crime groups or something else entirely. I'd avoid them unless I was already into grey or directly criminal activities and already had layers of protection and indirection in place.
