I have a Surface RT & was going to use the pre-installed Calendar app for the 1st time (tablet just given to me earlier this month). I don't want to have to sign-in each time just to check my own dates, I am not going to sync at all & don't want/need to put my dates into the "cloud" or have Microsoft see what I have dated.

What's a good-great app that I can just open & get to my dates w/o having to sign-in to sync anything?
