I usually use vpn tools. those vnp app always slow down my internet connection. I'm using HMA Pro for my desktop and psiphon app apk for my smartphone. They all work well but some days ago i found that Google and even some websites are still able to track my own IP. I also read a post about VNP software/apps, they told these apps are totally useless. So should we use vpn app? What you said really scares me. :-s
