## What is Fratera NullKey?

Fratera NullKey is a zero-knowledge vault for the things you cannot afford to lose: logins, API keys, server credentials, database details, identities, payment cards, secure notes, authenticator codes, photos and videos.

Your vault is encrypted on your device before it syncs. The service receives ciphertext—not your readable secrets—and cannot derive the key needed to decrypt them.

ORGANIZE EVERYTHING
Keep different kinds of sensitive information together without turning your vault into a junk drawer. Use folders, projects, environment labels, filters, sorting and fast search to find exactly what you need.

BUILT-IN AUTHENTICATOR
Generate time-based one-time passwords beside the accounts they protect. Add TOTP details directly or import compatible authenticator QR codes, then copy a fresh code when you need it.

FAST, PROTECTED ACCESS
Use encrypted Quick Unlock with a PIN and Face ID. NullKey also protects your information when you leave the app with background locking and an app-switcher privacy shield.

AUTOFILL ON IPHONE
Enable the NullKey Password AutoFill provider to fill normal login entries in Safari, other browsers and apps. Hidden and decoy vault entries stay outside AutoFill by design.

PRIVATE PHOTOS AND VIDEOS
Create an encrypted media library with folders, thumbnails and video playback. Photos and videos are encrypted before upload, and decrypted exports use short-lived local files that are cleaned up immediately.

READY OFFLINE
An encrypted local cache keeps your vault available without a connection. Changes queue safely and synchronize when you reconnect, with conflict preservation for competing edits.

MORE PRIVACY CONTROLS
• A separately encrypted Hidden Vault for your most sensitive items
• An optional local decoy vault and lockdown response
• Automatic vault locking, reveal hiding and sensitive clipboard clearing
• A secure password generator
• A local-only Security Audit for weak, reused or missing passwords, URL health and saved 2FA status
• A Recovery Key and Emergency Kit flow for the main vault

NULLKEY CAN STORE
Logins, secure secrets, API keys, servers, databases, credit cards, identities, crypto wallets, notes, TOTP authenticator details, photos and videos.
Your data should be useful to you—and unreadable to everyone else.
