I am relatively paranoid and don't trust too many third party apps...so Helium is not an option. I also do not root. From what I have seen the only way to backup app data other than root or Helium is to *HOPE* the developer incorporates specific backup APIs into their app. At least iTunes would brute force this backup (it doesn't have to be cloud for me, I am perfectly fine with manual backups). How can an OS as mature as Android not have even this most basic of features.
