Privacy Policy

Last updated: December 24, 2025

1. Introduction

Welcome to Cifrus. We are committed to protecting your personal information and your right to privacy. When you use our platform, you trust us with your most sensitive data. We take this responsibility seriously and are transparent about our security practices.

2. Zero Knowledge Architecture

Cifrus operates on a Zero Knowledge architecture. This means:

  • We do not have access to your master password or encryption keys.
  • We cannot decrypt or access your stored data (passwords, notes, files).
  • All encryption and decryption happen locally on your device.

3. Information We Collect

We collect the minimal amount of data necessary to operate the service:

  • Account Information: Your email address and a salted, hashed version of your authentication credential (which cannot be used to decrypt your data).
  • Encrypted Data blobs: The encrypted data you sync to our servers. We cannot read this data.
  • Usage Data: Anonymous metrics about platform performance and errors to help us improve the service.

4. How We Use Your Information

We use your information solely to provide, operate, and maintain the Cifrus platform. We do not sell your data to third parties. We do not track you across other websites.

5. Data Security

We implement military-grade encryption standards (AES-256) and robust security measures to protect your data. However, remember that no method of transmission over the internet is 100% secure. Your role in keeping your master password safe is crucial.
