Active in background. I installed this for a trial. It didn't do much they other browsers don't. What worried me is that although the app is closed, it's cache increases daily even though it hasn't been used. What is it doing in the background, unknown and unannounced? How can it claim to offer privacy when it's active and communicating with someone somewhere doing something unknown and unwanted by me? I've uninstalled it because of those privacy concerns.
