Local Data Storage – Persisting Data on Mobile Devices

Why Local Storage? Local data storage is essential for apps that need to retain user data between app sessions, even when the device is offline. Using efficient storage solutions ensures that your app remains responsive and fast.

Options for Local Data Storage:

1. SharedPreferences (Android) / UserDefaults (iOS): Store key-value pairs for small amounts of data (e.g., user preferences, app settings).
2. SQLite: A relational database system for storing structured data. Both Android and iOS support SQLite databases for more complex data storage.
3. Room Database (Android): A higher-level abstraction over SQLite that simplifies database management in Android apps.
4. Core Data (iOS): A powerful framework for object graph management and persistence, used for storing complex models in iOS apps.

Choosing the Right Storage Solution:

• Use SharedPreferences or UserDefaults for simple settings or small data (e.g., user authentication tokens).
• For larger datasets, use SQLite, Room, or Core Data depending on the platform.
• Ensure that data is encrypted if it involves sensitive information.
