The fact that you think content data would be stored in the app itself is testament to the lack of technical knowledge that many holders here have and therefore make ill informed decisions and advice.

Content data isn't held in the app. It is held elsewhere and simply accessed by the app. Sometimes, like netflix for example, you will have the option to store the program / movie locally on your device in which case it is drawn from the server and sent to you device.
