Telegram has two different encryption schemes: - client to server, server to 2nd client - full end2end encryption The first is default and stores all communication in plaintext on telegram servers. The first scheme enables universal search, instant "cloud backup" for the whole communication of that account, instant access for newly deployed devices, etc. The second works only on demand, is restricted to 1:1 chats, doesn't work in the browser and is generally not used that much among regular users who don't know about the feature.
