**Note**

The terms *audiences* and *segments* are interchangeable. Optimizely has updated all *segments* to *audiences* in the **Audiences** page and is currently working on updating the UI in other pages. See [Understand audiences](docId\:dDfAWzmas1k5te6cg5C4y) to get information on audiences.

Optimizely Data Platform (ODP) collects and stores your customer data, making it available to you in ODP for segmentation, reporting, campaigns, and more. Some of this data is considered personally identifiable information (PII), which is any data that you can use to directly or indirectly identify a person.

You can manage which fields are marked as PII, which of those PII fields users can still view as suggestions in features like audience building, and which ODP users have access to manage or view PII fields to ensure your customer data remains secure and private.

## User roles required to access PII

To view fields marked as PII (regardless of whether they are suggestible), you must have the **PII Viewer** role. Having this role alone does not let you select which fields are PII and suggestible, it just lets you view the data for those fields. The **PII Viewer** role also lets you:

- Test and preview campaigns
- View customer profiles
- Access the GraphQL page
- Interact with audiences and data throughout ODP

Users without the **PII Viewer** role do *not* have access to the features listed above.

To [mark fields as PII and suggestible](docId\:W3Ahe6Yp371wKcVWmjRu5), and view the data for those fields, you must have both the **All Access** and **PII Viewer** roles.

Manage these [user roles in the Opti ID Admin Center](docId\:W3Ahe6Yp371wKcVWmjRu5).

## Mark fields as PII and suggestible

If you have both the **All Access** and **PII Viewer** roles, you can manage which fields are set as PII and suggestible in **Data Setup > Objects & Fields**.

- **PII** – When you select this checkbox for a field, the data in that field becomes accessible only to users with the **PII Viewer** role. Users without the **PII Viewer** role cannot access it and instead see a confidential label in place of the PII data.
- **Suggestible** – When you select this checkbox for a field that you marked as PII, users without the **PII Viewer** role get access to the data for that field as suggestions in ODP features like audience building.

### Example: Only PII enabled

For users without the **PII Viewer** role:

If you only have the **PII** checkbox selected for the **Country** field, a confidential label displays in place of the country.

When building audiences or using other features that require you to set values for fields, a list of suggestions for the **Country** field does not display.

In this scenario, users can manually enter a country when they select **Contains** while building the audience. There is no indication if the country they enter matches one stored in ODP.

### Example: PII and Suggestible enabled

For users without the **PII Viewer** role:

If you have both the **PII** and **Suggestible** checkboxes selected for the **Country** field, a confidential label displays in place of the country.

However, when building audiences or using other features that require you to set values for fields, a list of suggestions for the **Country** field displays.
