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.
I would recommend reading up on Matrix if you’re going to use it in some kind of oppressive regime or whatever. E2EE works but compared to alternatives like Signal it sends a LOT of plaintext metadata.
I believe there used to be alternative solutions for dealing with MDM and remote wipes, but I’m not sure if that’s still allowed with modern API protections. Prey used to offer a kill switch, but I don’t think they still do on mobile devices. Perhaps there are others, I’m not very familiar with these apps. They mostly target businesses and business owned devices, but perhaps you could look for something that still offers a data wipe feature.
Its my understanding the metadata is only stored on the home server that runs for the clients, so under a self host scenario the hoster would be the only party that could access such metadata. One big con to Matrix is that it lacks ephemeral messaging so I’m not sure if chat history is stored on client side once the server goes offline? I cannot find an answer through browser search or documentation. Couldn’t the hosted server be restarted anytime and it would essentially delete the metadata generated each cycle and chat history as well because the chat room would be deleted? Or ran inside say persistent Tails and with a device shutdown or unplug all data would be wiped due to its ram only nature while persistence only keeps the base setup of matrix not a full carbon copy so a new chat would be generated each power cycle. Similar to VPN services running on ram. Thoughts anyone?
