# Enable privacy snapshot for React Native



In the [App Programming Guide for iOS](https://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html#//apple_ref/doc/uid/TP40007072-CH4-SW8), Apple says:



> When an app transitions to the background, the system takes a snapshot of the app’s main window, which it then presents briefly when transitioning your app back to the foreground. Before returning from your `applicationDidEnterBackground:` method, you should hide or obscure passwords and other sensitive personal information that might be captured as part of the snapshot.



This react-native module obscure passwords and other sensitive personal information when an app transitions to the background.
