You have probably seen the Preferences screen while using an Android app. You can save preferences and settings and share them with other users. But this is a very cumbersome way to do it. And, more importantly, this is not a secure way to do it. You should only use it if you know what you are doing.

In fact, the Android platform provides several options for developers to save application data. But the most frequent solution is the Shared Preferences framework. It's a simple way to store private primitive data in key-value pairs.

But in the case of a rooted device, theses files can be read, edited, and even deleted.
