SnapChat, an app on most mobile platforms that allows you to send images to recipients which are then deleted after a short period of time passes (think seconds), has gone public with the number of requests that it receives from “law enforcement branches of the government” on specific accounts and requesting copies of the information stored on these accounts.
According to their latest blog posting, in which they highlight how their service works, they state that in the event that a warrant comes in for the files associated to one or more of their accounts SnapChat is able to hand over any *currently unoppened* Snaps (Snaps are the picture files sent through the app), and hold any future Snaps to BCC to the appropriate agency.
SnapChat has long been used for sharing private data (read: nudes) with other users with the assumption that their “sensitive data” is being protected and will be deleted within 10 seconds of retrieval. This has long been disproved, in July the Atlantic Wire ran a story on how Android devices don’t actually delete your Snaps, and how in iOS, one can simply take a screenshot to save any and all Snaps.
I doubt the sensitive data sharing will slow now that it is public that government agencies can intercept your Snaps.
