A lot of people might say "latency" or "security": both are valid points but... What about the Data? on a native app I usually can SAVE data wherever I want on

A lot of people might say "latency" or "security": both are valid points but... What about the Data? on a native app I usually can SAVE data wherever I want on my device. I can even save it or load it from external storage like... a usb thumbdrive. And if my connection goes down I sill can use it (unless I have a license/activation software that needs to be connected to the internet).
