Telegram Goes Nuclear With New Message Deletion Feature

Messaging apps increasingly allow for some form of implicit privacy. But a backlog of sometimes years-old chats can still present a vulnerability. In its most recent update, Telegram believes it has solved that problem and then some.


The major overhaul—which sets it apart from even chat apps with disappearing message functions—is that Telegram now allows users to delete messages from both their end of the conversation and the recipient’s device.

“An old message you already forgot about can be taken out of context and used against you decades later. A hasty text you sent to a girlfriend in school can come [to] haunt you in 2030 when you decide to run for mayor. We have to admit: Despite all of our progress in encryption and privacy, we have very little actual control of our data,” creator Pavel Durov wrote on his personal channel.

Destructibility doesn’t apply only to your own messages either. Curiously, any user in a chat can delete any message. And the removal of a message doesn’t require the consent of the other user, nor does it generate an alert that a message was removed or a placeholder to indicate some media is missing. If the process of 86ing messages one by one sounds prohibitively time consuming, there’s also the option to nuke an entire chat, again, whether the other parties want it or not.

It’s bizarre, and at first, it’s a bit disconcerting. However, messages that seem important can always be forwarded to other users or into the “saved messages” folder. Telegram’s update addresses this potential vulnerability too by baking in a sort of “deep background” option:

We’ve also introduced a way to restrict who can forward your messages. When this setting is enabled, your forwarded messages will no longer lead back to your account — they’ll just display an unclickable name in the “from” field. This way people you chat with will have no verifiable proof you ever sent them anything

For journalists, I can see these features being useful to give control and peace of mind to sensitive sources. For everyone else? The abilities to selectively delete and then screengrab chats mean there’s some potential for abuse. Still, Telegram deserves some credit for pursuing a novel approach.

Correction: an earlier draft referred to Telegram as “Russia-based.” It’s founder is Russian but the company itself is registered elsewhere, and is presently based in Dubai. We regret the error.

Wouldn’t the logical next step be to create an app that allows you to easily screencap chats and store metadata on them? Maybe that’s effectively Evernote?

One another note, why would you ever use this app (especially if you were a woman) as a normal individual unless you were in a conspiracy with someone? It just seems like you’d expose yourself to abuse for which you’d have no recourse.

Edit: and by the way, as someone that has received pretty horrible emails/chats from parents associated with the youth groups I’m involved in, the next feature I would want is the ability to block anyone from sending me something I could not retain. If you don’t want it preserved or shared, I don’t ever want to receive it.
