From Android Docs: https://developer.android.com/training/data-storage/shared-preferences

If you have a relatively small collection of key-values that you'd like to save, you should use the SharedPreferences APIs. A SharedPreferences object points to a file containing key-value pairs and provides simple methods to read and write them.

Use shared preferences for small key value pairs, eg Storing a user id or some setting variable based on which the app experience would be defined further.

Your options are SQLite or Room (SQLite Wrapper) databases, if data is expected to grow so much (GBs or more), go with remote storage with either Firebase or privately owned server database
