Evernote’s Privacy statement states that: “As a rule, Evernote employees do not monitor or view your personal information or Content stored in the Service, but it may be viewed if we believe our Terms of Service have been violated and confirmation is required, if we need to do so in order to respond to your requests for user support, or we otherwise determine that we have an obligation to review it as described in our Terms of Service.” … There are ways to encrypt specific notes – see How to Encrypt Evernote on a Mac – but I prefer to stick with a global solution Recommendation – Ensure your locals disks/phone have adequate encryption and set a PIN for your Evernote app(s) (premium feature) Summary On the whole I think it’s sensible to take a moderate view on what you send to the cloud in Evernote, and for those documents that are more secure consider either keeping them in an offline notebook on an encrypted volume, or encrypting the document itself before you attach it to your note.
