I want to make an app remember some data that a user puts in even after he turns off the phone (like auto-login). How can this be done in React Native? Or which libraries/components should I research?

If you want to do something like auto-login you should probably be using react-native-keychain so that you can store user credentials in the keychain on the device in a more secure way.
If you are looking to store a particular application state or other non sensitive data you could use react-native-simple-store which provides a really simple wrapper around AsyncStorage and takes care of the boilerplate JSON.stringify/JSON.parse that you need to do for objects and arrays.
Hope that helps!

you can use flux stores, async store to store the current state in store, and re-route based on the store
can use componentWillMount mixing for setting up state before rendering view. for e.g.:
componentWillMount() {
LocalStorage.bootstrap(() => this.setState({bootstrapped: true}));
},
you can refer https://github.com/brentvatne/flux-util/blob/master/lib/flux-util.js for example.

You can use AsyncStorage bundled with react-native. It creates key value pairs
AsyncStorage.setItem("key", "value").done() // both key and value have to be strings
AsyncStorage.getItem("key").then((value) =>{}).done()
You can check the documentation for more options https://facebook.github.io/react-native/docs/asyncstorage.html#content

Note that this is unencrypted and shouldn't be used for sensitive user data
