Your files.
Your keys.
Your device.
Void Vault is a zero-knowledge encrypted file vault. AES-256-GCM encryption, fully offline, no cloud, no accounts. What goes in the vault stays in the vault.
Everything you need to protect your files
A complete encrypted vault with a built-in file manager, media viewers, and security features — all running locally on your device.
AES-256-GCM Encryption
Military-grade encryption for every file. Each file gets its own random key, wrapped by your master key.
Zero Knowledge
No accounts, no cloud, no tracking. Your PIN never leaves your device. We can't see your files even if we wanted to.
Fully Offline
Works without internet. Your encrypted files live on your device, not on someone else's server.
Built-in File Manager
Browse, search, sort, and organize files on your device. Grid and list views, category filters, storage stats.
In-Vault Viewers
View images, videos, PDFs, and text files directly inside the vault without decrypting to disk.
Biometric Unlock
Unlock your vault with fingerprint or face recognition. Fast access with the same strong encryption underneath.
Security isn't a feature — it's the foundation
Void Vault is built from the ground up around cryptographic primitives. No shortcuts, no "encrypt later" — every file is encrypted before it touches disk.
Per-File Encryption Keys
Every file gets its own random 256-bit key, wrapped by your master key. Compromising one file key doesn't expose the rest.
PBKDF2-SHA256 Key Derivation
310,000 iterations to derive your master key from your PIN. Brute-force attacks are computationally impractical.
Intruder Detection
Optional silent selfie capture on failed authentication. Encrypted and stored locally — only you can view them.
Auto-Lock & Vault Wipe
Configurable auto-lock timeout. Optional vault wipe after 15 failed attempts destroys all encrypted data.
Decoy Vault
Set up a separate PIN that opens a decoy vault with different files. Plausible deniability built in.
Screenshot Protection
Block screenshots and screen recording while the vault is open. Your files don't leak through the screen.
