A paper-only journal would defend against the state, but not against people you live with. A digital journal can be encrypted, but an intelligence agency could potentially gain access (like, them reading your anti-government rants that may involve violence… that sort of stuff).
So… how to defend against both threats?
(Also, I just realized, paper journals cannot really be easily backed up…)
Then simply write it in a text editor without saving it into a file, it’ll be lost after closing the program.
Unless you have a keylogger installed.
True, but then you have bigger problems than just the journal.
Agreed, but that was kind of the premise of the discussion, I think.
