Does SafeZone protect against "Sniffers" on a Wifi network (Unsecured)

Hello,
When i’m out and about I use public wifi.
My question is, if i’m using SafeZone does it encrypt my data and or use VPN so I cant be tracked?
I know it secures against DNS hijacks and software installed on my pc from recording anything, but what about the owner of the public wifi? Can they still see what I’m logging into? such as banking?

Thanks =)
