Disclosed herein is a communication method between two or more users which involves using a single software application to switch between a first mode of electronic messaging and a second mode of electronic messaging. Both the first mode of electronic messaging and the second mode of electronic messaging are between a first electronic device associated with a first user and a second electronic device associated with a second user. In the first mode of messaging, inputs are received from the first user for composing a regular message which is then sent to the second user in data transmitted through a server and saved in a memory. In the second mode of messaging, inputs are received from the first user for composing a confidential message which is then sent to the second user in data transmitted through the server, and the data is irretrievable at a later time.
