Back up app data before reset?

[StarStrider]

Hi, I have an HTC One running 4.3 and I've been having a lot of problems since the update. I'm about to do a factory reset to try and fix it, but I was wondering if there is a way I can back up app data (ex. my game saves) before doing so? I know how to do it through recovery, but my phone isn't rooted so I don't have any of those options available. I know this is been asked before, and I don't know if I'm supposed to be asking here, but if you could help or show me where to go that would be much appreciated!
