There’s a big difference between privacy and security, In a nutshell, security is the confidentiality of your data, while privacy is the appropriate use of your data.
Of course, without confidentiality (encryption), your data can be intercepted and used inappropriately, so entirely unencrypted transmissions are always susceptible to privacy violations.
