Q&A:Why Does Your Site Say Not Secure In The Browser Bar?
Donald Bohanon: That means the site is not secure to enter credit card information and make purchases primarily.
We are not requiring anyone make purchases or enter credit card information so we didn’t feel a need to add an SSL Certificate which essentially adds another layer of encryption in the event some one purchases something or is using a credit card in some other way.
So again we are not asking for credit card information nor are we selling anything, all the information we provide is free.So we didn’t feel the need to add an SSL Certificate for an added layer of security and encryption.So that’s why it says “Not Secure” in the browser bar.
