Productivity utilities sync with PC, not with cloud

[mtlue5]

What apps are there that will allow me to enter and manage the data and backup all on PC? Not just enter /manage on the smartphone and backup to a cloud. I do not like all my data going to some cloud server.
App types I am looking for are:
- tasks/to-do's
- information lists
- journal/diary
Any advice is appreicated.
Thanks
Mike
