How to use Snapchat’s Chat feature
The feature allows you to connect with friends one-on-one, or have a group chat with several people. For individual chats, messages are automatically deleted once you both leave the chat. Group chat messages are deleted after 24 hours.
If you don’t want a message to disappear, you can press and hold to save it, but keep in mind that the other in the chat will be able to see that you have done so since the background of the message will turn gray.
