# 5. Data and Persistent Storage

This module will deal with persistent storage to the Android phone, as well as storage across an application session (from open to close of an app). These topics will be particularly useful for developing applications that are client facing, though you will see in the future that most meaningful application data is stored online rather than locally.

### Topics
