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.
There’s no way to prevent someone from retaining data once they have it. The clients would have to voluntarily cooperate.
Are there matrix clients that do this? Only fetch messages from server when needed and not store locally?
I guess probably, because Matrix is thought for private chatting, i guess someone else might have had this same idea, i think matrix is opensource so there must be some client that does this.
Even if there is, though, that would only affect you and the messages you read. If you sent it to others, they could still do what they wanted with it.
