Krypt

Read full description

Krypt is a fully offline, AES-256 encrypted vault for iPhone. Every password, note, file, and 2FA code you store is encrypted and kept exclusively on your device — never sent to a server, never synced to a cloud, never shared with anyone. ENCRYPTED FILE VAULT Import photos, documents, and scans directly into the vault. Each file is individually encrypted. Scan physical documents with your camera and store them as encrypted PDFs — passports, contracts, bank statements, anything sensitive. PASSWORDS Store unlimited logins, PINs, and credentials. Generate strong passwords with the built-in cryptographic generator. Copy passwords to clipboard with one tap — automatically cleared after 30 seconds so nothing lingers. BUILT-IN 2FA AUTHENTICATOR Replace Google Authenticator. Store your TOTP codes inside the same encrypted vault as your passwords. No separate app, no separate risk. FACE ID & TOUCH ID Unlock instantly with biometrics. Or configure Face ID to open the decoy vault — your real data stays hidden even under biometric pressure. THE DECOY VAULT Set a second PIN that opens a completely different vault. If anyone ever pressures you to unlock your phone, show them the decoy. They will never know the real vault exists. BUILT TO PROTECT ITSELF Wrong PIN attempts trigger increasing lockout periods. After 10 failed attempts the vault permanently wipes itself — leaving no trace of your data. WHAT KRYPT NEVER DOES — Never connects to the internet — Never syncs to iCloud — Never tracks you — Never shows ads — Never sells your data SECURITY ARCHITECTURE AES-256-GCM encryption. PBKDF2-SHA256 key derivation with 310,000 iterations. Keys stored in iOS Keychain with device-only binding — never extractable, never backed up to iCloud. Screenshot detection. Clipboard auto-clear. App switcher cover. Krypt is free to start, with encrypted backup import and export included. Krypt Pro unlocks unlimited storage, the file vault, built-in 2FA authenticator, and the decoy vault.

visualOS is an infinite canvas for people who think visually. It is an infinite canvas for notes, folders, images, to-do’s and sketches. It works fully offline and saves to real files in a folder on your device. YOUR DATA IS A FOLDER YOU CAN OPEN Connect any folder on your disk and visualOS mirrors your canvas into it — every folder on the canvas is a real folder, every document a Markdown file, every image an image. Put the folder in iCloud or Dropbox and it syncs through your cloud, not ours. If you ever leave, everything stays readable. Forever. OFFLINE ISN'T A MODE. IT'S THE ARCHITECTURE. On a flight, on the train, in a studio with no signal — visualOS doesn’t care. There is no server to reach, so there is no spinner, no sync wheel, no login wall. Your canvas opens instantly because everything is already here. BOARDS WITHIN BOARDS Any board can hold more boards. A project becomes a world: moodboards inside client boards inside your studio. Drag elements into a board to file them away; breadcrumbs keep you oriented; a double-tap takes you deeper. NO ACCOUNT. NO SUBSCRIPTION. Open it and work. There's nothing to sign up for, nothing to verify, nothing to cancel. Pay once and it's yours forever — one purchase unlocks every Apple device. FREE IN THE BROWSER BUT THE APP GOES FURTHER Try visualOS free in your browser at visualos.app. When you're ready for it everywhere, the app adds what a browser can't: true offline access on the train or a plane, native pan-and-zoom gestures, Apple Pencil drawing, and your boards saved as real files that sync across iPhone, iPad and Mac through your own iCloud. EVERYTHING ELSE • Notes & rich text • Long-form documents stored as plain Markdown • Interactive to-do lists on the canvas • Images & PDFs — drag, paste or drop them in • Freehand drawing • Magnetic arrows that snap and bend • Search every board at once • Groups, locking and a snap grid Your ideas. Your files. ABOUT US As creatives, we’ve always relied on visual canvas tools to organize our thoughts, plan projects, and make sense of ideas. But one thing kept bothering us: our files and knowledge were always tied to cloud-based services. We wanted the freedom to access everything offline, without worrying about losing our work or giving up our privacy. So why can’t our own files on our device be visualized in the same intuitive way? And that’s how the idea for visualOS was born: a visual representation of your internal folder structure — offline, private, and secure. Your data stays on your device, where it belongs. We’re Sarah and Gerald, a husband-and-wife team who have been living, loving, and building things together for more than 20 years. Creating visualOS has been a ton of fun and thanks to AI we were able to push it further than we initially imagined. Now we’d love to hear what you think. If visualOS helps you work a little more creatively or makes your files easier to navigate, we’d be grateful if you shared it with others.
