Data

API Reference: Data

Data is an interface for storing key value data on Device and can be used for storing

• Detecting one time activity such as showing a user for a welcome page
• Theme Information
• Language Information

Location of Local Storage on Device

On Android, Data is stored under /data/data/APP_NAME/SharedPref/JS.xml

On iOS, Data is stored under /var/mobile>Contatiners>Data>Application>APP_NAME>Library>Preferences>SF_USER_DEFUALTS.plist

Stored areas are accessible by the app itself only unless the device is rooted. That is why before storing critical data, it is advised to use encryption. To learn more about natively encrypted data, refer to the SecureData documentation:
