It doesn't matter whether you use cloud or sd card. The fact that we are are using a piece of technology that we think we own is open season on our "no longer private information". The moment you enter information on the mobile device Apple, Samsung, Google and other companies has free access to our data. We paid for the device, but we really don't own it. They (i.e. Apple, Google...etc) control our phones and they can collect info, modify settings, push (install) apps without us knowing or our permission. So, using cloud service is just a neat way to backup/store and retrieve data without having to re-install everything if you were to reset the phone. And sd card do backup data but, doesn't auto-restore. It is more secure if you encrypt all info, but that will cause other problems such as slowing the system down and take up more memory. Plus companies still can access the sd card for info as expected. The more we use the latest tech the easier and more data companies collect. We don't own the devices we pay for.
