Full description
Welcome to Knock Messaging! • Send messages and media instantly • View shared content quickly via secure links • Lightweight and fast experience • iMessage extension support (iOS) • App Clip support for instant preview (iOS) We’re excited to launch the first version of Knock Messaging. More improvements coming soon! 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.
