Signal: A Free, Privacy-Focused Encrypted Messaging App

Overview

Core Features and Advantages

🔒 Top-Tier Encryption Technology

• End-to-End Encryption: All conversations—including messages, voice calls, and video calls—are automatically encrypted using the state-of-the-art, open-source Signal Protocol. This means only the communicating parties can read your messages or listen to your calls; even Signal servers cannot access your communication content.
• Privacy by Default: Privacy is not an optional feature you need to enable manually—it’s the default and inherent way Signal operates. This principle applies to every message sent and every call made.

✨ Free and Feature-Rich

• Rich Multimedia Sharing: Send text, voice messages, photos, videos, GIFs, and various files, all completely free.
• High-Quality Calls: Enjoy crystal-clear voice and video calls, regardless of distance, without incurring long-distance charges. Signal uses your data connection for communication, effectively avoiding carrier SMS and MMS costs.

🎨 Personalization and Fun

• Encrypted Stickers: Add a new dimension of expression to your conversations with fun, encrypted stickers.
• Create and Share: Users can unleash their creativity by designing and sharing their own custom sticker packs.

👥 Convenient Group Chats

🚫 Ad-Free and Uncluttered Experience

🌍 Independent Nonprofit Model
