Server-side hashing converts personal identifiers like email or phone number into irreversible encrypted values before sending them to analytics or ad platforms. Because hashing occurs on the server, raw data is never exposed in the browser. This method supports privacy-safe attribution and enhanced conversions without violating regulations.

Key Points
• Encrypts identifiers before they leave your infrastructure
• Prevents raw personal data exposure in browsers
• Enables privacy-safe conversion matching
• Supports GDPR and healthcare compliance needs
