Signal is the better pick when default privacy matters: chats and calls are end-to-end encrypted by default, and clients are open source. Telegram is better for large public groups, Channels, bots, and cloud chats you can open on any logged-in device. Telegram’s default cloud chats are not end-to-end encrypted — only Secret Chats are. Pick by use-case.
Deciding factor: By use-case: Signal for default privacy; Telegram for large groups, Channels, and bots.
Key fact: Telegram Secret Chats are end-to-end encrypted; default Telegram cloud chats are not. Signal’s default chats are.

Yes for default chats. Signal encrypts messages and calls end-to-end by default and publishes open-source clients. Telegram’s default cloud chats are encrypted between the client and Telegram’s servers and stored in the cloud; only Secret Chats are end-to-end encrypted (Telegram FAQ). If you never enable Secret Chats, Signal’s default is the stronger privacy posture.
No. Telegram’s FAQ states that Secret Chats are end-to-end encrypted and that ordinary cloud chats are stored on Telegram’s servers so they can sync across devices. Signal’s default 1:1 and group chats are end-to-end encrypted. Do not treat “Telegram is encrypted” as the same claim as “Telegram is end-to-end encrypted by default.”
Telegram. Official docs describe groups with a very large member cap and Channels for one-to-many broadcasts, plus a public bot API. Signal supports encrypted groups sized for private circles, not public broadcast communities. Use Telegram for public or very large communities; use Signal for private groups.
Signal still registers with a phone number and offers optional usernames so contacts need not see that number (Signal Support). Telegram also uses a phone number to create an account and can show a username in public contexts (Telegram FAQ). Neither is a pure email-only messenger.
It depends who is already installed. If the goal is private family chat with default end-to-end encryption, Signal matches that job. If the family already lives in Telegram groups or Channels, Telegram is easier — but default cloud chats are not end-to-end encrypted. There is no MAU ranking.
Neither is a full WhatsApp Business replacement. Telegram documents bots, Channels, and large groups that creators and communities use. Signal has no official business API. For customer messaging with a verified business profile, see WhatsApp Business instead. For private staff chat, prefer Signal if everyone can install it.
Signal publishes its clients and the Signal Protocol. Telegram publishes clients and documents its APIs, but default cloud-chat encryption is not the same as Signal’s default end-to-end model. Open source does not by itself make Telegram’s default chats end-to-end encrypted.
Analysis: Signal vs Telegram
Signal or Telegram depends on default privacy versus large-community features. No user counts are added.
Privacy and encryption
Signal encrypts chats and calls by default and publishes protocol and client source. Telegram’s FAQ distinguishes Secret Chats (end-to-end encrypted, device-to-device) from cloud chats (stored on Telegram servers so they sync). Treat that distinction as load-bearing: a Telegram group or Channel is not a Secret Chat.

Features and communities
Telegram documents large groups, unlimited-audience Channels, bots, and large file transfers. Those are the reasons people pick Telegram for public communities. Signal’s feature set is narrower and privacy-oriented (disappearing messages, sealed sender, usernames).
Choose Signal if every participant can install it and you want default end-to-end encryption. Choose Telegram if you need Channels, bots, or very large groups and accept that default cloud chats are not end-to-end encrypted. Related: Signal vs WhatsApp; WhatsApp vs Telegram.
