About this app

CallSec is a security-first communications platform for encrypted messaging, voice and video calls.

MILITARY-GRADE ENCRYPTION
End-to-end encryption, built on an audited open-source cryptographic core, ensures only you and your recipients can read messages or hear calls. Not even the server can access your content.

SECURE VOICE & VIDEO CALLS
Crystal-clear encrypted calls with TURN relay mode that prevents IP address leaks. Multi-device support — receive calls on all your devices simultaneously.

ADVANCED DEVICE SECURITY
• Root/jailbreak detection
• IMSI catcher detection with cell tower database
• Screenshot and screen recording prevention
• USB debugging and developer options detection
• Microphone spy detection during calls
• Overlay attack protection

PRIVACY CONTROLS
• PIN, pattern, or biometric app lock
• Panic PIN — triggers emergency data wipe under duress
• Dead Man's Switch — auto-wipe if you don't authenticate within set days
• Disappearing messages (on-send and on-read modes)
• Incognito keyboard and clipboard auto-clear
• Secure notifications (content hidden on lock screen)

SELF-HOSTED & ON-PREMISES
Deploy on your own infrastructure for complete data sovereignty. No cloud dependencies. True on-premises deployment with federation support between organizations.

MULTI-DEVICE
Use CallSec on multiple devices with the same account. Device approval workflow ensures only authorized devices can access your communications.

GROUP COMMUNICATIONS
Encrypted group chats and multi-party video calls. Share files, images, and voice messages — all end-to-end encrypted.

CallSec is designed for organizations and individuals who require the highest level of communication security.
