About this question
I have been using LibreOffice now, and I'm encrypting files of LO Write with VeraCrypt that have very personal content and I want to keep it confidential. But I read about LO send to his web SO MUCH information, and I read an entry (that I cannot find again right now) that says he save so much secret information using LibreOffice like me, he have Comodo Firewall and he sees that the trusted files list of his Firewall, get double when he installs LO and sees that that files send a few KB of information. And he starts a difficult uninstall of LO all files.
So, is Libreoffice safe in terms of writing and opening files with it. Should I change to OpenOffice or any other software?
