WhatsApp has introduced disappearing messages. Making the announcement, the company in a statement said, "Today, WhatsApp messages often live on our phones forever. While it’s great to hold onto memories from friends and family, most of what we send doesn’t need to be everlasting. Our goal is to make conversations on WhatsApp feel as close to in-person as possible, which means they shouldn't have to stick around forever. That’s why we’re excited to introduce the option to use disappearing messages on WhatsApp." When disappearing messages is turned on, new messages sent to a chat will disappear after 7 days, helping the conversation feel lighter and more private. In a one-to-one chat, either person can turn disappearing messages on or off. In groups, admins will have control. "We’re starting with seven days because we think it offers peace of mind that conversations aren’t permanent, while remaining practical so you don’t forget what you were chatting about. The shopping list or store address you received a few days ago will be there while you need it, and then disappear after you don’t. You can read more, including how to enable disappearing messages here," the company said. Here are some features of the service:

• If a user doesn’t open WhatsApp in the seven day period, the message will disappear. However, the preview of the message might still be displayed in notifications until WhatsApp is opened.
• When you reply to a message, the initial message is quoted. If you reply to a disappearing message, the quoted text might remain in the chat after seven days.
• If a disappearing message is forwarded to a chat with disappearing messages off, the message won’t disappear in the forwarded chat.
• If a user creates a backup before a message disappears, the disappearing message will be included in the backup. Disappearing messages will be deleted when a user restores from a backup.
