Field Hashing for PII Protection

Data Extraction
March 23, 2026

Protect sensitive data without losing analytical value. Field hashing lets you apply irreversible SHA-256 encryption to string property fields directly within your extraction order — before data ever reaches your warehouse.

Key Benefits

  • Privacy by default — PII fields like emails and user IDs can be hashed before storage, reducing exposure risk
  • Join-friendly — identical inputs always produce the same hash, so hashed fields still work as join keys across datasets
  • Zero code required — enable hashing with a checkbox in your extraction order settings

Notes:

  • Available for string property fields only (not metrics or dimensions).
  • Not yet available for all report types — if you don't see the Hashing column, contact your CSM
