Snapchat is unable to provide copies of Snaps to Snapchatters. Delete is our default. This means opened or expired Snaps typically cannot be retrieved from Snapchat's servers by anyone, for any reason.
In most cases, opened Snaps are automatically deleted once they have been viewed or have expired. Snapchat servers are designed to automatically delete unopened one-on-one Snaps after 31 days.
However, if you feel a crime has been committed, we encourage you to contact your local police.
