Good point — I think this falls under the category of pitfalls of closed-source privacy software. The developers say the software does not route traffic through a single server. You have to take their word for it that that is true since you can’t see the code.

There may be other ways of figuring out what happens to the traffic, such as traceroutes, without the code — but of course those methods are not foolproof.

If JonDo does actually route traffic through multiple proxies as described, it’s better than a VPN, where everything goes through a central server.
