"Calc gives you a few different ways to protect your information
from prying eyes (I realized that this is what they were talking
about, instead of just saving the info). You can hide just the
cells of your document – either one or many – if you so
choose. To do this, right click on your selection and then choose
Format Cells. You will find all the options necessary for hiding
all or part of your information under the tab marked Cell
Protection. To protect an entire page, go to Tools/Protect
Documents/Sheet and select a password."
