Knock Messaging makes it easy to send secure messages and media instantly.

The app provides a shortcut tool that allows users to quickly compose and send encrypted messages while using supported messaging apps. When activated, a small floating shortcut appears on the screen, allowing the user to create and send a secure message without leaving their current conversation.

Key Features:
• Send encrypted messages and media instantly
• Lightweight floating shortcut for quick access
• Secure link-based message delivery
• Simple and fast user experience

Accessibility Service Disclosure: Knock uses the Android Accessibility Service solely to display a floating shortcut button over messaging apps, enabling you to send end-to-end encrypted messages directly from your SMS app. This service does NOT read, store, or share your SMS messages or personal data. You can disable it anytime from Android Settings > Accessibility.
