In active development · Phase 2.6
A video conferencing platform like Zoom or MS Teams — but engineered around host privacy, not against it.
VaultCast wraps every session in multiple privacy layers. Built-in screenshot and screen-recording blocks, on-device AI that detects when a participant tries to record the screen with a second camera (and alerts the host in real time), tier-based DRM, dynamic watermarking, and a hardened native Android shell. Built end-to-end — backend, web, and mobile.
Privacy & protection layers
Screenshots blocked
FLAG_SECURE on Android, screen-capture protection on web — OS-level, not app-level.
Screen-recording stopped
Tier-based DRM — Widevine L3 (Shaka Player) on web, Widevine L1 (ExoPlayer) hardware-backed on the Android shell. Decryption keys never leave the device's secure chip.
External camera detection
On-device AI (YOLO + MediaPipe) flags participants pointing a phone camera at the screen — the host gets an instant alert with the offending tile.
Dynamic watermarking
Per-viewer overlay (email + session id) baked into the stream — any leaked recording is traceable.
Hardened mobile shell
Capacitor-wrapped native Android with privacy-blur on app switch and SafetyNet attestation before sessions start.
Auto-cutoff sessions
Session-length policies enforced server-side. Hosts can extend, viewers can rejoin — nothing lingers.
Five tiers, one product
Plans differ by session length, concurrent viewers, and DRM strength — the privacy floor stays the same on every tier. DRM strength: L3 = software-based (web browsers, broad reach) · L1 = hardware-backed in the device's secure chip (strongest protection, mobile shell).
