backup my data, writing in App

[galaxy01]

My phone, Lush Smart, has 4.4.2,
Like to back up my writing in App, Keep my notes,

Ran Super backup, and apk file is saved in internal storage,
Is my writing backuped and saved?

No, just the app is.

If the app doesn't have a "save" item in its menu, find an app that does, and use that instead. Whether an app saves its data (and writing is data to a writing app) is up to the developer of that app - some do, some don't.)

1. do you know which one does?
2. I do not see "save" in this App, so clicked "backup", where to find this backup?
