title: What is the naming convention for keys of AsyncStorage in React Native?
body: <p>In the official AsyncStorage example:
  <a href="https://facebook.github.io/react-native/docs/signed-apk-android.html" rel="noreferrer">https://facebook.github.io/react-native/docs/signed-apk-android.html</a>
  Every key value has a <code>@myAppStore:</code> prefix.</p>
  
  <p><code>await AsyncStorage.setItem('@myAppStore:key', '{ "data": [...] }');</code></p>
  
  <p>However, in <a href="https://stackoverflow.com/questions/39028755/save-sensitive-data-in-react-native/39112472#39112472">Save sensitive data in React Native</a>, it seems Android and iOS both have their sandboxes, so the data is (kind of) secured.</p>
  
  <p>Does the <code>@myAppStore:</code> prefix define the scope (eg. like creating a new collection in NoSQL), or it just a naming convention?</p>
