Kryptos vs Volume Shader

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 Privacy policy: https://kryptos.faizalmzain.com/privacy Terms and FAQ: https://kryptos.faizalmzain.com/faq

Volume Shader is the viral Volume Shader BM GPU test, built natively for iPhone and iPad. The Mandelbulb ray march runs in Metal on your iPhone or iPad. WHAT YOU CAN DO • Run Volume Shader BM at Simple, Standard, Advanced, or Extreme • Use Standard + 30 seconds when you want a score you can compare • Drag to rotate, pinch to zoom, and pan. Explore does not save a score. • Time CPU and memory on the same device • See GPU, memory, display, storage, and thermal state • Walk a display, touch, haptics, speaker, and battery checkup HEAT AND BATTERY This is a real GPU workload. The device can get warm and the battery will drain faster while a test is running. Extreme asks for confirmation. The app stops itself if iOS reports a critical thermal state. ADS Volume Shader is free and shows labeled native ads on Test, Device, and Checkup. Ads sit below the main content on those screens. They do not overlay the GPU test or fullscreen checkup steps. You can report an ad from the AdChoices icon on the ad. PRIVACY No account. Tests, history, and checkup marks stay on this device. Nothing is uploaded. If you tap Share, iOS’s share sheet sends only what you chose to the app you pick. Ads use the ads SDK described in the privacy policy.
