title: Synchronize user data to Google account
body: <p>I want to synchronize my app's data between several Android devices. To make it simple for user, I want to somehow use Google account.</p>
  
  <p>So my question is - does Google provide some free cloud storage? My app's data shouldn't be bigger than 50MB. If not, is there any free alternative or workaround (for example saving data to user's Drive)?</p>
