## What is Kryptos?

Kryptos is a zero-knowledge personal vault for your most sensitive documents - passports, ID cards, driver's licences, payment cards, API keys, and private notes. Everything is encrypted on your device with AES-GCM (256-bit). We never see your data, and we can't.

ZERO-KNOWLEDGE BY DESIGN
Your vault is sealed with AES-256-GCM using Apple's CryptoKit. The encryption key is stored in the iOS Keychain with kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly - it never leaves your device. There is no Kryptos server holding your secrets. Even cloud backups upload only opaque, encrypted bytes.

SMART DOCUMENT SCANNING
Snap a passport, a driver's licence, an ID card, or a payment card. On-device VisionKit and Live Text extract the fields automatically. Camera frames never leave your iPhone.

QR CODE CAPTURE AND REGENERATION
Point the camera at any QR code to import its contents. Kryptos can regenerate the same QR from the saved entry whenever you need it.

CROSS-DEVICE SHARING - FULLY OFFLINE
Share any entry with someone else's Kryptos app by showing a QR code on screen. They scan it from their device and the entry imports instantly with the right category, title, and fields. Nothing touches the network - sharing happens completely offline, screen-to-screen.

BEAUTIFUL HERO CARDS
Each document type gets its own purpose-built card UI - passports, driver's licences, credit cards, IDs, notes, API keys, tax numbers - with a scanned attachment rendered as the card itself.

EXPIRY REMINDERS
Add an Expiry field to any entry and Kryptos sends a local notification 30 days, 7 days, and 1 day before it expires. All scheduled offline through local notifications - no cloud dependency.

FACE ID AND TOUCH ID UNLOCK
Lock your vault behind biometric authentication backed by the Secure Enclave.

ENCRYPTED CLOUD BACKUP
Auto-backup your encrypted vault to your choice of iCloud (private CloudKit database) or your own Google Drive:
- Free: hidden Drive AppData folder
- Pro: a visible "KryptosBackups" folder, easier to manage and copy off-device

Neither iCloud nor Google Drive can decrypt the backup. Only your device can.

MULTI-ACCOUNT ISOLATION
Each signed-in account (Sign in with Apple or Google) gets its own fully isolated, separately encrypted vault. Switch accounts without entries leaking between them.

PRICING - SIMPLE AND FAIR
- Free: store up to 10 entries, full features, no ads.
- Kryptos Pro: $1.99 one-time. Unlimited entries, visible Drive backup, priority support, and all future Pro features included.

No subscriptions. No recurring fees. Pay once, own it forever.

WHY KRYPTOS
Most "secure" vaults are convenient because they hold your data on someone else's server. Kryptos picks the harder path: your data stays on your device, encrypted with a key only you control. The trade-off is that we can never reset your vault for you - but it also means no breach, leak, or subpoena exposes your secrets.

PERMISSIONS WE REQUEST
- Camera: to scan documents and QR codes (on-device only)
- Face ID or Touch ID: to unlock your vault
- Notifications: for expiry reminders
- Internet: only for Sign in with Apple or Google, iCloud sync, Drive backup, and App Store purchase verification

WHAT WE DO NOT DO
- Run a server that stores your vault contents
- Show ads or embed advertising SDKs
- Sell, share, or analyse your data
- Hold a copy of your encryption key
