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.

Images are displayed in an album mode in which an image occupying a focus position is separated by bars from adjacent images in the album. The bars serve as a visual separator between the images and signify to a user that the images can be vertically scrolled. If the focus image occupies less than the full height of the screen, then part of the adjacent images are shown above and below the focus image. If the focus image occupies the full height of the screen, then the image is reduced in size to occupy less than the full height, causing the adjacent images to also be displayed. If the user scrolls the image, the image reduction decreases linearly with the scrolling until the image is shown at full height. Continued scrolling causes the image to move off the screen and the previous or next image to be displayed.

A messaging server receives a sharing message from a sharer client indicating that the sharer client is offering to provide live location information. When the messaging server receives a subscription request from a receiver client indicating a request to receive live location information shared by the sharer client, the messaging server sends a location request to the sharer client. The location request requests live location information from the sharer client. The sharer client determines its location using a location module and sends live location information to the messaging server in response to the request. The server sends the live location information received from the sharer client to the receiver client. When no receiver clients send subscription requests, the sharer client does not send live location information, thereby preserving power by limiting use of the location module.
