## Description

Lock your words and files behind a password. Entirely on your iPhone. No accounts, no servers, no tracking. Strong Argon2id + XChaCha20 encryption, built in.

Quietbox locks your private words and files behind a password — and nothing else. No accounts to create, no servers to trust, no internet connection required. Everything happens on your iPhone, and your password never leaves it.

WHAT IT DOES
• Encrypt any text or file with a password.
• Decrypt it later — on any iPhone with Quietbox and the same password.
• Encrypted text becomes a block you can copy and paste anywhere: a note, a message, an email.
• Encrypted files become a .quietbox artifact you can copy, share, or save.
• Open a .quietbox file from the Files app or a share sheet to decrypt it.

PRIVATE BY DESIGN
• 100% on-device. No accounts. No network. No analytics. No tracking.
• Your password lives in memory only long enough to do the work — never written to disk, never logged, never sent anywhere.
• Because there is no backend, no one — including the developer — can see your data or recover it for you.

STRONG, MODERN ENCRYPTION
• Argon2id (RFC 9106) turns your password into a key and resists brute-force cracking.
• XChaCha20-Poly1305 authenticated encryption protects and verifies your data.
• A wrong password or tampered data fails loudly and safely — Quietbox never hands you garbage output.

THOUGHTFUL DETAILS
• Live password-strength meter and confirm-password to prevent lockouts.
• Progress feedback for the deliberately slow key derivation.
• Full Dark Mode, Dynamic Type, and VoiceOver support.
• Built for the latest iPhone look with the new Liquid Glass design.

IMPORTANT
If you lose your password, your data cannot be recovered. Keep it somewhere safe — Quietbox holds no keys and has no way to reset it. That is exactly what makes it private.

Lock your words and files behind a password. That's Quietbox.
