Photos and notes that self-destruct. Set expiration timers (24h to 30 days) and watch them fade away automatically. Gone forever.

Dual-vault system. Enter your backup PIN to unlock a decoy vault with innocent photos while keeping your real vault hidden. Plausible deniability.
// Silent vault switching

Store sensitive text notes with same encryption as photos. Create permanent Vault notes or self-destructing Fade notes.
// Photos + Notes in one vault
SECURITY FEATURES
Screenshot protection, network alerts, two-factor authentication, secure deletion (DoD 5220.22-M), encrypted backups with double encryption.

How It Works
ChaCha20-Poly1305 AEAD
Authenticated encryption with associated data. Each photo is encrypted with a unique 256-bit key stored in iOS Keychain with hardware-backed security.
// Used by Signal, Google, Cloudflare
Zero-Knowledge Architecture
We never see your photos. We never see your keys. Everything is encrypted locally on your device. No cloud sync. No servers. No analytics. 100% offline.
// 100% local encryption
Encrypted Backups
Double encryption (ChaCha20 + AES-256) with PBKDF2 key derivation. Export your vault as a .nu11vlt file with password protection. 100,000 iterations for brute-force resistance.
// Password never stored
