True Privacy by Design

Our zero-knowledge architecture ensures we never have access to your sensitive data. Everything happens locally in your browser.

  • Your encryption keys are generated locally in your browser
  • Keys never leave your device - we cannot access them
  • Protected content is encrypted before any network transmission
  • No server-side storage of your sensitive data
  • Audit trail stays local - only you know what you protected
  • Full GDPR compliance through privacy-by-design

How File Anonymization Works

Click the "Anonymize File" button in ChatGPT, Claude, or Gemini. Select a text file (max 50KB), preview detected entities, choose your protection method, and the anonymized content is uploaded directly to the chat. When using encryption, AI responses containing your encrypted values are automatically decrypted and highlighted.

Enterprise Deployment

Deploy organization-wide with enforced policies and centralized management.

Pre-Configured Deployment

Package the extension with enforced encryption rules, preset configurations, and predefined entity lists.

Enforced Policies

Administrators can enforce encryption settings that users cannot override. Ensure compliance across the organization.

Silent Installation

Deploy via Group Policy, MDM, or enterprise browser management. No user action required.

Centralized Templates

Distribute organization-wide templates and custom entities. Ensure consistent protection standards.

Administrator Control

Administrators can package the extension with:

  • Enforced encryption algorithms and key lengths
  • Pre-configured protection presets
  • Organization-specific custom entities
  • Locked settings that users cannot modify
  • Automatic key rotation policies
  • Audit logging configuration
