Measurement privacy is an additional settings page with no current sidebar entry. Open it using this direct app link. Owner or Admin access is required to edit a policy. It applies to the selected measurement subject, not every workspace model. Scheduled and ended subjects are read-only.

​
Configure a subject

  1. Choose Measurement subject and check its lifecycle status.
  2. Set First-party measurement and its purposes: Analytics, Attribution, or Experimentation. Capture needs an enabled policy and the required consent.
  3. Choose Consent behavior: Deny without policy, Consent required, or First-party only. First-party only needs Analytics or Experimentation.
  4. Choose Privacy classification: Restricted, Healthcare-capable, or General. These are policy classifications for data handling.
Restricted forces capture off. Non-General classifications use aggregate-only reporting and disable PostHog diagnostics. Healthcare-capable also has Minimum reported cohort, with choices of 10, 20, 50, or 100 people.

​
Diagnostics and retention

PostHog diagnostics is available only for General classification. Clarity diagnostics is unavailable. Observation retention offers 30, 90, 180, 395, or 730 days. Subject-key retention offers 7, 30, 90, 180, 395, or 730 days. Subject keys cannot be retained longer than observations. Optional diagnostics do not determine whether first-party measurement is ready.

​
Save and review history

Select Save privacy policy and check the reloaded subject. Policy history shows versions, settings, actor, and effective dates. It has no rollback control.
