Signal Private Messenger

Private messaging without the clutter

Signal Private Messenger is a communication app for people who want ordinary chat, voice calls and video calls with strong privacy protections. It supports text messages, photos, files, voice messages and group conversations over an internet connection, making it a practical replacement for standard SMS and a more private option for everyday contact.

What it keeps private

Messages and calls use the open-source Signal Protocol for end-to-end encryption. In practical terms, conversations are designed so that only the people involved can read or hear them. The Signal Foundation develops the app as a nonprofit rather than an advertising-led social network, and the service does not fill the interface with ads or tracking features.

Useful for individuals and groups

• Send text, voice messages, photos and other files in one conversation.
• Make encrypted voice and video calls over mobile data or Wi-Fi.
• Use group chats for family, friends, clubs or small teams.
• Share temporary Stories updates with control over who can view them.

Is it a good fit?

Signal suits users who want a familiar messenger without giving up privacy, including people moving away from ad-supported platforms and groups handling sensitive conversations. Its interface stays close to the conventions of mainstream messaging apps, so the security features do not require a specialist workflow. Registration still requires a phone number, which may not suit anyone seeking complete anonymity, and its decorative extras are less extensive than those found in larger social messaging apps.

With a 4.55 rating from more than 2.8 million reviews and 100,000,000+ installs, Signal is an established choice in the Communication category. It is developed by the Signal Foundation.
