Does Telegram read your messages?
By default, it can. Telegram's ordinary chats are not end-to-end encrypted, so its servers can technically access the contents. On metadata: no.
Even when contents are encrypted, the service usually still sees who you talk to and when. Telegram's identifier model: Phone number is the primary identity; a public @username can be added. Anonymous blockchain numbers via Fragment are possible but paid and not the default.. RVNT removes the server from the equation entirely — peer-to-peer, sealed sender, Tor by default: RVNT vs Telegram.
