HTTPS and other encryption methods help prevent targeted advertising, tracking, and information theft. Tools like HTTPS Everywhere can attempt or require HTTPS in web browser connections. Are there any tools to similarly attempt or require encrypted connections throughout device internet connectivity on smart phones? If so, what are some examples, and in either case, what are some of the notable issues / limitations faced when trying to secure mobile devices from tracking, targeted advertising, and information/identity theft?
Disconnect.me, or Tor's Orbot with root mode, may be examples but I'm not sure yet if they handle the many potentially-leaky holes that come with smart phone apps. I'm also not sure how practical (using Orbot in root mode) or secure (relying on Disconnect.me's VPN) those options are, but that set of trade-offs is a whole conversation in itself.
