It runs on device and it's fairly easy to analyze the traffic, you are not giving a third party all your access. You could proxy all the traffic through a Mac running LittleSnitch, read their code, inspect the VPN profile it installs on the device, etc. It will only have access to your internet traffic if you opt-in in the actual VPN tunnel service they sell, which is optional.
