  description

  CLOKR — AI Privacy Shield is a Chrome extension that helps protect your privacy when using AI chat tools.
  
  It detects common sensitive data patterns in what you type and replaces them with placeholders before the message is sent to external servers (example: [email protected] → [EMAIL_1]). This helps reduce the risk of accidentally sharing personal information.
  
  Protected data types:
  
  Email addresses
  
  IBAN numbers
  
  Italian tax codes (Codice Fiscale)
  
  Phone numbers
  
  Key points:
  
  Local processing in your browser
  
  No telemetry and no data collection
  
  Open source: https://github.com/progetticyber/clokr-extension
  
  After you install it, you can keep chatting normally while CLOKR masks sensitive details in real time.
