Protecting your personal and confidential information since 2009, Krypton is the first, simplest and most reliable App on the iOS Store to strongly encrypt entire documents and folders. Now also available on the macOS App Store. Your stuff is secure from prying eyes no matter where you are in the world. Metaphorically, Krypton keeps your encrypted items in a special vault, with each item contained in their own deposit box; to gain access to an encrypted item the vault must be open and the passcode key must be used to unlock the deposit box before you can discern the plaintext contents inside. In iOS the vault may be open or closed, while on macOS the vault opens upon Log In. Because the unit of encryption is an entire document or folder, Krypton is not a password manager in the traditional sense, although you can maintain a document of all your passwords that you encrypt between uses. Krypton can encrypt any type of document, including but not limited to: • Pictures and movies from your photo album. • Email messages from your mailbox. • Songs, PDFs, movies, Zip files, word processing documents, text files, images, program source code or any other object that you can download over the network or from your personal web server. • Anything on the iOS pasteboard. • Any document other Apps are willing to Share, such as Pages, Numbers and Keynote. • iCloud Drive and Dropbox files for easy cloud synchronization. Krypton uses strong encryption on each item. This has several ramifications: • If your passcode is strong enough to withstand a brute force attack, no one is going to see your stuff. • If you forget your passcode, no one can recover your stuff for you! But only that one document is lost, not your entire collection of items. • Your stuff is secure even if your iDevice or Mac is stolen, or iCloud Drive or Dropbox account is compromised.

File->Save is a private, encrypted vault for your photos, videos and documents, wrapped in a retro terminal interface that makes protecting your files feel like being the hacker in a heist movie. NO CLOUD. NO ACCOUNT. NO TRACKING. Everything is encrypted and stored on your device only. There is no server, no sync, no analytics peeking at your files. Your password never leaves your head; your keys never leave your phone. SERIOUS ENCRYPTION * ChaCha20-Poly1305 encryption for every file * A random 256-bit master key, wrapped with your password (PBKDF2, 210,000 rounds) * Even file NAMES are encrypted on disk * No password hash is stored. The math itself is the lock. * Change your password instantly, without re-encrypting your vault BUILT FOR REAL PRIVACY * Decoy vault: a second password opens a completely separate vault, and no one can tell it exists (Premium) * Panic actions: shake or tap to lock instantly, wiping keys from memory * Auto-lock the moment you leave the app, or after 5 minutes * Offline-only mode: the vault refuses to open while any network is connected (Premium) * Password-protect individual folders (Premium) YOUR FILES, UNTOUCHED * Imports are byte-for-byte: original quality, original file names, EXIF and capture dates preserved. No recompression, ever. * Sort and filter each folder your way; every folder remembers its own order * Built-in viewer for photos, videos, audio, PDFs and documents * Scan paper documents straight into encryption, never into the camera roll (Premium) ENCRYPTED BACKUPS * Export a fully encrypted backup and restore it on any device with just your backup password * Backups preserve folder structure, names, dates and metadata * Your backup password is the only key. Even we can't open it. A VAULT WITH CHARACTER Green-on-black terminal interface, typed animations, a built-in command line, and maybe a hidden game or two for those who explore. FREE & PREMIUM The core vault is free. Premium unlocks unlimited files, the decoy vault, offline-only mode, folder passwords and the document scanner: monthly, yearly, or a single lifetime purchase. IMPORTANT There is no password recovery. That is the point: no backdoor exists, for anyone. Choose a password you'll remember, and export encrypted backups regularly. Your files. Actually private.
