App Development
We Build Apps
People Trust.
Kryven Technologies builds native Apple apps that are purpose-built, privacy-first, and designed to feel like they belong on your device.
Our Approach
Built on Principles, Not Promises
Every app we ship follows the same architecture. Your data stays in your Apple ecosystem, encrypted on your device, with no Kryven servers involved.
Zero-Knowledge Design
Kryven Technologies has no servers and no user accounts. Your data lives entirely in your own Apple ecosystem. We have no ability to access, view, or decrypt your content. There is nothing on our end to breach.
Built on Apple's Infrastructure
Every app uses CoreData and CloudKit, the same frameworks powering Apple's own apps like Notes and Reminders. Sync, storage, and sharing all run through Apple's infrastructure. No third-party backends.
Native Apple Experience
Built with SwiftUI for iPhone, iPad, and Mac. Biometric lock via LocalAuthentication. Sharing that works like iCloud sharing. No account to create. Your Apple ID is all you need.
Our Apps
Purpose-Built. Privacy-First.
Each app solves a specific problem with the same zero-knowledge architecture underneath.
Kryven Vault
Secure personal document storage for iPhone, iPad, and Mac. IDs, passports, insurance, credit cards, warranties. End-to-end encrypted and organized.
