Abstract
Methods, systems, and storage media for providing ephemeral messages are disclosed. Exemplary implementations may: receive, at a first device, a request from a first user to send an ephemeral message to a second user; encrypt the payload of the ephemeral message; send the ephemeral message to the second user according to the recipient identifier; store the ephemeral message locally on the first device of the first user and the second device of the second user; and delete the ephemeral message from the first device and the second device upon expiration of the specified duration of time.
