## What it is
Silence is an Android SMS/MMS messaging app that encrypts messages end-to-end using the Signal protocol, working entirely over the cellular network with no servers or internet connection. It is a fork of TextSecure that preserves encrypted SMS, and the project has moved to git.silence.dev with GitHub as a mirror.

## Use cases
- send encrypted sms messages on android
- text privately without internet or a messaging service
- protect sms messages if my phone is lost or stolen
- replace my default sms app with an encrypted one
- message friends securely without them installing a new service

## When to choose
- you need encrypted SMS/MMS over the cellular network without internet
- you want to avoid servers, accounts, or Google services dependencies
- you want a fully open-source, auditable messaging app

## When to avoid
- you want modern internet-based encrypted messaging like Signal itself
- you need active development and recent updates (last release 2021)
- you need iOS or desktop support

## Facets
- artifact type: application
- maturity: maintenance
- function: security, cryptography, chat-interface
- domain: privacy, messaging-platforms, android-tools, security
