@LittleCat_Kat It is, it is. Good for you! Always ensure your stories are safe, that's the first priority.
I've been writing offline since the beginning and using multiple means of backups, so even if something happens to an online service, or my computer(s), I can still be safe knowing my stories won't be gone.
My writing app does automatic backups, which sync to iCloud, and my stories are saved on DropBox. Which automatically syncs with my smartphone and other computers. So at any given moment, I have at least three local copies, and two live online copies, plus backups.
