Basically I am looking for a messaging platform like signal or? but with anonymous signup, perfect forward secrecy, capable of video chat, sending photos the usual uses in today’s life. But with a panic button. So that any party member could use said button to wipe all other members devices of any data instantly inside the messaging app. So if one member gets compromised, or lost their device, stolen device ect, any other member could wipe all chats, call log, and any other data strictly inside the messaging client instantly for everyone involved. Disolving the group like it never existed rendering the data unrecoverable. Amazons Wickr used to have most of these features but it is being discontinued December 2023 and who trusts amazon with their data. Does something like this exist? Sorry if I’m not explaining it well I’ll do my best to clarify and update this post. I am not trying to delete the whole device. Just the data inside the messaging app. If that does not exist. What about a separate app that could delete the entire messaging platform from the device when triggered. Assume all necessary requirements are met and this is for daily use. Between a group of trusted parties.
Updated wording to clarify the objective as replies where getting misunderstood.
First things first, there is no app like you describe. You have to take my word for it. Let’s say a certain country’s law enforcement might be very interested in taking to me if it knew role in certain events.
I examined many messaging and chat platforms, and the closest to what you’re asking for are custom Telegram clients that go a longer way to ensure that TG’s local data gets deleted properly (by default it doesn’t, easy peasy to get data from the local DB, half cleansed chats from 6 months ago pop up in exports or even the UI, etc).”, has a built in double bottom for accounts, etc. An example of what I am talking about is here: https://github.com/wrwrabbit (check the repos yourself).
Secondly, you must understand that when the law enforcement seizes a phone, upon initial quick examination (sometimes using brutality to force you to unlock it), they will shut it down to ensure it is not connected to the Internet. And then criminalists will use a special black box device sold by an Israeli cybersec firm (its name always escapes me, but I think the product might be called Pegasus) to extract all data for offline analysis.
So thirdly, you must not rely on any app that conditionally removes data from a device. You must not entrust your well-being to it. Which leaves you basically the only choice: only ephemeral messaging capabilities which are available only when you are in the app, through the server over which you have full control.
Or your messaging sessions must take place only when you’re in a secure location. And even then you should have a “wipe all button” in case the police come after you unexpectedly.
