This is the main issue I have with app security. It would be great if one could deny network access to apps. I would be much more willing to install many apps if I knew they would keep the data local and not be able to send my data to some insecure cloud service for sale to the highest bidder behind my back.
It would be cool if app stores showed which apps require network access and which don't.
