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 Messaging uses the Android AccessibilityService API to display a user-activated floating shortcut while the user is in a messaging app. This shortcut allows the user to compose and send an encrypted message without leaving the current screen. The AccessibilityService is used only to detect the active messaging screen and display the shortcut tool when enabled by the user. Knock Messaging does not read, collect, store, or share message content or personal information using AccessibilityService. The service is only activated after explicit user consent and can be disabled at any time in device settings.
