CipherMind Shield
6 layers of protection that work together to keep your communication private.
Ghost Mode
Self-destructing messages with configurable timers (30s to 7 days). Timer starts after the recipient reads the message. Each message auto-deletes independently.
Screen Shield
Prevents screenshots and screen recording on Android (FLAG_SECURE). Active across the entire app when enabled. Desktop toggle available.
Phantom Metadata
Strips all identifying metadata from files before sending. EXIF data from photos, encoder info from audio — removed automatically.
Trust Verify
Verify contact identity via QR code scan or 60-digit safety numbers. Emoji fingerprint visualization for easy verification. Alerts on key changes.
Vault Lock + Decoy Mode
Hide sensitive conversations behind a separate PIN. Decoy Mode: a second PIN shows an empty vault — plausible deniability built in.
Panic Wipe
Emergency data destruction. Long-press the lock icon (3 seconds), enter PIN, confirm with biometrics — all local data wiped instantly. No server communication.
Messaging Features
Encrypted Messaging
Text, images, voice messages — all encrypted with Signal Protocol before leaving your device.
Voice Calls
1:1 encrypted audio calls via WebRTC. SDP/ICE signaling encrypted with Signal Protocol. Server is a relay only.
View Once Media
Send photos that can only be viewed once. Screenshot protection active during viewing. Auto-deleted after closing.
Privacy Controls
Control who sees your online status, last seen, and read receipts. Server enforces your choices.
Encrypted Backup
Export your data as an AES-256-GCM encrypted backup file (.cmbackup). Password-protected with PBKDF2.
Message Search
Search through your messages locally. All searches happen on your device — nothing sent to the server.
