Snapchat has updated its privacy policy to allow it to view and publish any image that a user sends over the self-destruct messaging app, forever. The new terms state that while Snapchat users retain ownership rights to whatever content they choose to share over the messaging app, by deciding to use the service, they are hereby granting Snapchat a perpetual licence to view, host, publish, display, promote and adapt the content in any way the app chooses to do so.
