Signal

Signal helps when you need conversations that stay private and free from tracking. Built by an independent nonprofit and powered by open source technology, it focuses on secure communication that is simple to use. Messages and calls travel over your data connection so you can stay in touch across borders, and the app avoids advertising and profiling. If you plan to download Signal, this overview explains what to expect before getting started.

Signal features

Signal applies end to end encryption to every message and call. The service cannot read your messages or listen to your calls, and it collects minimal metadata. There are no ads or trackers. The Signal Protocol and app code are open source for public review.

You can send texts, voice notes, photos, videos, GIFs, stickers, and files using your data connection. This helps avoid SMS or MMS fees from your carrier. Conversations continue whether you are on mobile data or Wi Fi.

When a call is better, Signal offers encrypted voice and video calls with clear audio and stable video. You can also start secure group calls with up to 50 people. Calls work across countries and networks.

For larger conversations, Signal supports group chats with up to 1,000 members. Admin tools help manage membership and control who can post. This setup works for families, clubs, classrooms, and communities.

Beyond encryption, you can set disappearing messages to remove chat history on a schedule. Usernames let you connect without sharing your phone number. Encrypted stickers and notification privacy options add control over what appears on your screen. You can also share image, text, and video Stories that expire after 24 hours and set who can view each Story.

Signal independence and transparency

Signal Private Messenger is developed by an independent nonprofit organization, not by an ad driven company. There are no advertisers or investors shaping product decisions. The app and its protocol are open source, which allows independent researchers and the community to review how it works.

Access and availability with Signal

In regions where messaging apps face network blocks, Signal includes support for proxy connections to help maintain access. Availability can vary by location and local rules, so users in restricted environments may need to configure a proxy before starting. This option can be helpful when traveling or working across borders.

How to use Signal on Android

The steps below outline the basics to start private conversations on an Android phone. Use the Signal latest version for the best experience and current security protections. The setup is quick and does not require extra accounts.

1. First, install and open the app, then follow the prompts to allow necessary permissions. Enter your phone number and verify it with the code you receive.
2. Next, set your profile name and photo. Create a username so you can connect with others without revealing your phone number.

4. After that, create a group from the new message screen, add members, and adjust admin settings as needed. You can also open any chat and tap the call button to start a voice or video call, or begin a group call in a group chat.
5. Finally, open a chat’s menu to turn on disappearing messages and choose a timer. Visit settings to adjust notification previews and choose who can view your Stories.
