# PII Transcription Cleaning

> Automatically redact personally identifiable information from interview transcripts to protect candidate privacy and support compliance.

When enabled, Alex automatically scans completed interview transcripts and redacts personally identifiable information (PII) before any evaluation takes place. This helps protect candidate privacy and supports compliance with data protection regulations. PII redaction has no effect on grading and candidates are evaluated fairly and accurately regardless of whether this feature is enabled.

### How It Works

PII Transcription Cleaning runs automatically as part of the post-interview evaluation pipeline. After the interview ends and the transcript is finalized, Alex detects and replaces sensitive information with `*****`, preserving the original sentence structure so the conversation still reads naturally.

### What Gets Redacted

**Contact Information**

* Phone numbers, email addresses, social profile URLs
* Street addresses, city + ZIP/postal code combinations, and full mailing addresses

**Government Identifiers**

* Social Security Numbers, national ID numbers
* Driver's license, passport, visa, green card, and work permit numbers

**Financial Information**

* Bank account numbers, credit card numbers, routing numbers
* Exact personal salary figures

**Medical Information**

* Medical record numbers
* Specific medical conditions tied to identity
* Genetic test information

**Protected Categories**

* Religion, race, ethnicity, sexual orientation, gender identity
* Political affiliation, disability or pregnancy disclosures, caste identification

**Age**

* Exact date of birth and explicit age statements (years of experience are **not** redacted)

### What Is NOT Redacted

* Company names, job titles, and role information
* Technical skills, experience, and education
* General geographic references (e.g., "I worked in Texas")
* General business discussion

### Enabling Transcription Cleaning

Go to **Settings → Interviews**, find the **Transcription Cleaning** toggle under the Candidate Experience section, and switch it on. Once enabled, all future completed interviews will have PII automatically redacted from their transcripts.

<Note>
  Enabling this setting only affects interviews completed after the change. Previously completed transcripts are not
  retroactively redacted.
