Neither are cloud based. You have them on your computer just like MS Office. They are both free. I think libre office is more advanced than open office but that's just my opinion. Botth are compatible to MS office.
They are bundled with so much PUP and PUM. Throw down a few bucks for an old MS Office 2007 Key (no more support so they’re cheap cheap). And always remember, nothing is for free. Those word, excel, emv, xml, have so much of your personal data housed within.
Just for kicks, use a XML editor and open a XML file you’re sending to a client (which presumably eventually finds its way to FNMA).
Notepad would work, but try a free 1 Month Trial of XML Editor. Exif photo data, the time you signed the doc, browser history & cookies, file types (jpeg, png, jpg, or btmp), your type of signatureur .ico file, sky maps, flood data mapping tools, Adobe X or Adobe 9? ACI? Those handy .xml files tell quite a story. So does the metadata housed within a PDF file. Scrub them free of YOUR metadata. Ohh, nothing to hide, I see.
Introducing... “Waivers”! And soon to come, their ugly cousin “Hybrids”!
The less you give, the smaller their dataset. What they don’t expressly mandate you tell them, is no USPAP violation.
