title: AssyncStorage saving data on build
body: <p>Hello I'm new at react native and im building a simple app that is saving an array and a value with asyncStorage, but after i build the app using Expo the data persists and is saved on the apk.</p>
  
  <p>How can I wipe the data on installation (a little bit inefficient, but for now it would do it becouse I just will probably have a couple of elements on the array) or on build (I dont know if it is possible) or other way... </p>
  
  <p>That's how i am saving the data.</p>
  
  <pre><code>const storeData = async (array) =&gt; {
          try {
              console.log("STORED");
              const jsonValue = JSON.stringify(array);
              await AsyncStorage.setItem("@sleep_data", jsonValue);
          } catch (e) {
              console.log("error saving")
          }
      };
  </code></pre>
