Zero - Secure and Discreet Messaging App

Zero is a messaging app designed to help protect your privacy and enable secure communication. The app uses end-to-end encryption, includes discreet features, and provides various security tools to help protect your information. Please note that no security measure is 100% effective, and we cannot guarantee absolute security or privacy.

🔒 Advanced Security Features:

• End-to-End Encryption (E2EE)

Messages, images, files, and voice messages are encrypted end-to-end. In normal operation, only you and the recipient can read the content. However, we cannot guarantee messages cannot be intercepted by third parties through technical means or security vulnerabilities.

• Screenshot Blocking

The app attempts to block screenshots on supported devices. However, this feature is not available on all devices, may not work in all circumstances, and can be bypassed. We cannot guarantee screenshots will always be prevented.

The app disguises itself as a simple calculator. Long-press memory buttons (MC, MR, M+, M-) to activate secret functions: login screen, biometric login, help guide, or panic button.
