Qualcomm is fully aware of the privacy implications of Gimbal, and has gone out of its way to make sure the technology does not get attacked for violating our personal space. For starters, Gimbal’s data collection mechanisms are all opt-in – you must give it permission to eavesdrop on your conversations, or track where you go, says Heidt. It also requires that you explicitly allow applications to access the data collected by Gimbal, all of which is stored directly on your device, rather than in the cloud.

My Humble Opinion:

IMO, currently all the information NUNCHI stores is on the server or in the cloud...Gimbal and NUNCHI sounds like a perfect marriage to me. We have the NUNCHI framework that can store all the information from the Gimbal app on a secure cloud server, process the information, and send the processed information back to the device securely.

Of course, this is just a good old boy's opinion. That and a couple of bucks will get you a cup of coffee at most shops.
