What is if someone deleted their snapchat account?

If someone deleted their Snapchat account, all of their data, including photos, videos, and chat history, will be permanently deleted and cannot be retrieved. Their username will become available for someone else to use after a period of time. When someone deletes their account, they lose access to all their friends, chats, and subscriptions. Their friends will no longer be able to send them snaps or messages, and they will no longer receive updates from their subscriptions. Additionally, any public snaps or stories they posted will be removed from the app's public feed. However, there is no way to know if someone has deleted their Snapchat account unless they tell you or you try to add them as a friend and receive a notification that the account does not exist.
