Our Product

Zodiac

Your keys. Your data. Never ours.

Zodiac is a zero-knowledge, end-to-end encrypted, quantum-resistant privacy suite. One account, one master password - a password manager, encrypted notes, a file vault and calendar, and post-quantum secure chat. Encryption happens on your device; our servers only store ciphertext.

One Suite

Everything private, in one place

Every module is encrypted on your device before anything leaves it.

Password Manager

Encrypted vault with favorites, edit history, strength meter, CSV import and encrypted sharing.

Password Generator

Cryptographically secure passwords and EFF-wordlist passphrases, generated entirely on your device.

Secure Notes

Encrypted notes with pinning, autosave and a rich editor. Sealed with AES-256-GCM.

File Vault

20 GiB of encrypted storage with chunked, resumable uploads. Every chunk encrypted on device.

Encrypted Calendar

Event titles and notes are encrypted. Only dates and times stay visible for scheduling.

Quantum-Resistant Chat

E2EE messaging with hybrid ML-KEM-768 + X25519 key exchange and ML-DSA-65 signatures.

Encrypted Sharing

Share accounts, notes and files via links whose keys never touch our servers.

Dead Man's Switch

Release encrypted letters, notify contacts or wipe your vault if you stop checking in.

Browser Extension

Autofill, TOTP codes, vault audit and biometric unlock - with a token scoped to your vault only.

Under the Hood

Serious cryptography, no compromises

Your master password never leaves your device. Keys are derived with Argon2id, held as non-extractable WebCrypto keys, and every field is sealed with its own AES-256-GCM key via HKDF.

AES-256-GCM Argon2id ML-KEM-768 ML-DSA-65 X25519 HKDF-SHA256 WebCrypto Zero-Knowledge

Radical Honesty

What our servers can see

Zero-knowledge means we cannot read your data - not that metadata magically disappears. We would rather tell you exactly where the line is.

Visible to the server

  • Username
  • Calendar event dates and times
  • File names, types and sizes
  • Chat social graph and message timestamps

Always ciphertext

  • Passwords and vault entries
  • Notes and file contents
  • Messages and shared content
  • Your master password - it never leaves your device

Membership

One-time payment. No subscription.

Every duration includes everything - there are no feature tiers. Keys stack, and an expired membership leaves your vault read-only. Nothing is held hostage.

Take back your privacy

Zodiac is built by Sivacy in the Netherlands, under European privacy law.
