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.

Ephemeral messaging in a decentralized end-to-end encrypted messaging platform

The present disclosure relates to systems, non-transitory computer-readable media, and methods for dynamically controlling ephemeral messaging threads and ephemeral message duration settings across computing devices while improving security by maintaining end-to-end encryption. In particular, in one or more embodiments, the disclosed systems can transmit encrypted ephemeral messages, including ephemeral message duration settings and ephemeral setting timestamps. The disclosed systems can decrypt received messages on receiving client devices and dynamically apply ephemeral message duration settings to different message threads. For example, the disclosed systems can modify existing duration settings at a receiving client device to match a received ephemeral message duration setting based on determining that the received ephemeral setting timestamp predates an existing setting timestamp. Further, the disclosed systems can apply the ephemeral message duration setting to delete ephemeral messages from an ephemeral message thread.
