Privacy Policy

Last updated: December 2025

Introduction

CIFER Security ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our website and services.

Our core product is built on the principle that your encrypted data should be accessible only to you. This privacy policy covers the information we collect about you as a user of our services, not your encrypted data which remains cryptographically protected at all times.

  • Account Information: Email address, name, and authentication credentials when you create an account
  • Contact Information: Information you provide when contacting us for support or inquiries
  • Payment Information: Billing details processed through our payment providers (we do not store full payment card numbers)

  • Usage Data: API calls, feature usage, and service interactions (excluding encrypted content)
  • Device Information: Browser type, operating system, and device identifiers
  • Log Data: IP addresses, access times, and pages viewed

Your Encrypted Data

Important: Data you encrypt using CIFER is processed exclusively within Trusted Execution Environments (TEEs). We cannot access, read, or decrypt your encrypted content. This is enforced by hardware—not policy.

  • Encryption keys are generated and stored within TEE enclaves

  • Service Providers: Third parties that help us operate our services (hosting, analytics, payment processing)
  • Legal Requirements: When required by law or to protect our rights and safety
  • Business Transfers: In connection with a merger, acquisition, or sale of assets

Data Retention

We retain your personal information for as long as your account is active or as needed to provide services. We may retain certain information as required by law or for legitimate business purposes.

Your Rights

Depending on your location, you may have the right to:

  • Access, correct, or delete your personal information
  • Object to or restrict certain processing
  • Data portability
  • Withdraw consent where processing is based on consent
