Telegram vs Signal: Privacy and Features Compared

Signal and Telegram are often recommended as privacy-focused messaging alternatives. While both prioritize user privacy, they take very different approaches.

Encryption

• Signal: End-to-end encrypted by default for ALL messages (Signal Protocol). No one, including Signal, can read your messages.
• Telegram: Client-server encrypted by default. E2E encryption only in Secret Chats. Telegram can technically access regular chat messages.

Features

• Telegram: Channels, bots, stickers, Mini Apps, large groups (200K), cloud storage, 2 GB file sharing. Significantly more features.
• Signal: Basic messaging, calls, stories, groups (1,000 max), no bots, no channels. Minimal but focused on privacy.

Data Collection

• Signal: Collects only your phone number. No message content, no contacts, no metadata stored on servers.
• Telegram: Stores messages in the cloud (except Secret Chats), collects contacts and some metadata. More data, but less than WhatsApp/Facebook.

Open Source

• Signal: Fully open source (client and server). Anyone can audit the code.
• Telegram: Client apps are open source. Server code is proprietary.

Verdict

For maximum privacy and security, choose Signal. For features, communities, and convenience, choose Telegram. Many security-conscious users run both: Signal for sensitive conversations, Telegram for everything else.
