SyncVault for Mobile
Your Files. Your Keys. Your Vault.
AES-256-GCM Encryption
Double-wrapped hardware keys, sealed with AES-256-GCM — the gold-standard cipher engineered to make brute-force a losing game.
The Ghost Reader
View PDFs and documents directly in RAM. Zero files are ever decrypted to your phone's storage.
Cloud-Free P2P Syncing
Direct peer-to-peer transfer over local Wi-Fi. No accounts, no servers, no Big Tech middlemen.
The Panic PIN
Enter a secondary duress code and your vault's keys are cryptographically shredded on the spot — gone in a blink, nothing left to recover.
Fortress Specs & Media
Stream chunked video and audio directly from the encrypted vault. Media is decrypted on-the-fly into application memory and served to the player without ever buffering to public storage or shared cache directories.
Organize your vault on your terms — create custom folder hierarchies, rename files in place, and move assets between containers. Every operation stays inside the encrypted envelope.
Distributed off-Play-Store. Manual licensing only — no third-party app stores, no automated tracking.

SyncVault for Android TV
Encrypted. On Screen. Off Grid.
P2P Fortress Syncing
High-speed peer-to-peer handshake with SyncVault Mobile beams encrypted folders straight to your TV. Local network only — no cloud, no accounts.
Tactical D-Pad Engine
Custom Focus Architecture replaces touch with a "Three-Stop Focus Trap" and double-click shield. Engineered for lean-back, never-miss navigation.
Hardware-Accelerated Theater
On-the-fly decryption straight into frame-buffer memory. 4K playback of encrypted files with zero buffering, wrapped in a Security Terminal HUD.
Terminal-Grade Lock Screen
A scrambled numeric keypad foils shoulder-surfers, live cipher-status readouts keep you in the loop, and the vault auto-arms the instant your TV drops to standby.
Cinema-Grade Decryption
Every file remains cryptographically sealed inside its AES-256-GCM Encrypted Envelope until the exact moment of hardware-accelerated playback. Decryption happens directly in the device's frame-buffer memory — never on disk, never in cache.
The TV acts as a trusted node on your local network. Pair once with the SyncVault Mobile app and beam entire encrypted folders over P2P. Cloud accounts never enter the loop.
Distributed off-Play-Store. Sideload-only APK with manual licensing — no third-party app stores, no automated tracking.
