Zero-knowledge, no storage: everything is generated deterministically using Argon2 + PBKDF2 + AES-CTR

Vaults (admin, member, team) are encrypted with AES-GCM

No sync, no telemetry, no backend – it's all client-side

TOTP-based onboarding for teams

Built as a PWA, works offline on any device

Would love feedback from the HN community on the crypto model, UX, and real-world use.
