App Development
We Build Apps
People Trust.
Kryven Technologies builds native Apple apps — 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 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 and iPad. IDs, passports, insurance, credit cards, warranties — end-to-end encrypted and organized. Mac coming soon.
