In a post that summarizes the changes, Evernote stated that it will allow some of its workers “to exercise oversight of machine learning technologies applied to account content.” It added that the number of those employees are “small” but did not offer a specific number. Customers have the option to encrypt any of their notes. It also stated:
While our computer systems do a pretty good job, sometimes a limited amount of human review is simply unavoidable in order to make sure everything is working exactly as it should.
Obviously, Evernote is trying to cover its bases on any potential problems it might find on its service, but if you are at all concerned that someone at the company might be looking at your notes, you might want to consider your other online note taking options.
