WhatsApp View Once Feature

Whats app rolling out new View Once photos and videos that disappear from the chat after they’ve been opened, giving users even more control over their privacy.
After the media has been viewed, the message will appear as “opened” to avoid any confusion.
 

About view once

•     Media will not be saved to the recipient’s Photos or Gallery.

•     Once you send a view once photo or video, you won’t be able to view it again.

•     You can’t forward, save, star, or share photos or videos that were sent or received with view once media enabled.

•     You can only see if a recipient has opened a view once photo or video if they have read receipts turned on.

•     If you don’t open the photo or video within 14 days of it being sent, the media will expire from the chat.

•     You must select view once media each time you want to send a view once photo or video.

•     View once media can be restored from backup if the message is unopened at the time of back up. If the photo or video has already been opened, the media will not be included in the backup and can’t be restored.

Note:

• Only send photos or videos with view once media enabled to trusted individuals. For example, it's possible for someone to: 

            * Take a screenshot or screen recording of the media before it disappears. You won’t be notified if someone takes a screenshot or screen recording. 

             * Take a photo or video of the media with a camera or other device before it disappears.
