Does anyone have more information concerning the claim that Telegram stores &quot;EVERY MESSAGE&quot; in plaintext? [1] Specifically is this true in any way for their end-to-end &quot;Secret Chat&quot;? I&#x27;ve been unable to find any proof to claims Moxie and Ptacek have been making on twitter. Considering Moxie makes a competitive messaging app, making these claims without clearer proof seems a bit reckless. So I would like to know if there is some proof out there that we have missed.<p>So far the responses Moxie and Ptacek have given to multiple requests are:<p>* API shows a string message object stored on server [2]. No clear indication that this is itself not a string representation of an end-to-end encrypted object.<p>* iOS devices receive push notifications indicating Telegram servers must be able to decrypt in order to send plaintext to Apple [3]. Not clear if this is true also for end-to-end encrypted secret chats.<p>1. &quot;By default Telegram stores the PLAINTEXT of EVERY MESSAGE every user has ever sent or received on THEIR SERVER.&quot;
