# Apply Privacy Shield to a data sync

## Enable Privacy Shield in a data-sharing request to mask or exclude sensitive attributes before syncing with a vendor application

Enable Privacy Shield in a data-sharing request to mask or exclude sensitive attributes when syncing roster data with a vendor application.

**Note:** Privacy Shield applies to future imports only. Data shared with the vendor before Privacy Shield was enabled is not retroactively masked.

### Before you begin

- You must have Primary District Admin permissions.
- At least one vendor application must be activated in your district.
- Mark attributes as sensitive before you turn on Privacy Shield, or masking will not apply. See [Mark sensitive data attributes](https://docs.google.com/document/d/1SXwBs0LwSc9U5uNbQZpb4xzjZUf9VlzCisi0ktAsBRQ/edit#).

### Enable Privacy Shield in a data-sharing request

When you activate a new application, Privacy Shield is enabled by default.

1. Go to **Applications** and select the vendor application.
2. Click **Request Changes**.
3. In the **Privacy Shield** section, turn on the **Privacy Shield** toggle.

4. Review the **Attributes** section. For each attribute, confirm the following:

5. **Available** checkbox — selected means the attribute is included in the sync. Clear it to exclude the attribute entirely.
6. **Privacy Shield Supported** checkbox — selected means the vendor supports masking for this attribute. If unavailable, masking is not supported for that attribute.
7. Click **Request Changes**.
8. Wait for the vendor to approve the request.

**Note:** After the vendor approves, masking is not applied until you run a data import from your SIS. See [Run a data import](https://help.schoolday.com/knowledge/run-sync-manually?hsLang=en).

### Run the data import

After vendor approval:

1. Go to your SIS or data source.
2. Run a data import.

Masking is applied during import. After the import completes, the vendor receives only masked or excluded data.

### Exclude a specific attribute from sync

If you want to prevent a specific attribute from being shared with the vendor entirely:

1. In the data-sharing request, go to the **Attributes** section.
2. Clear the **Available** checkbox for the attribute.
3. Click **Request Changes** and wait for vendor approval.

**Note:** If a vendor marks an attribute as required, the **Available** checkbox cannot be cleared. The attribute will be shared regardless of your sensitive data settings. To check which attributes are required, review the application requirements or contact [SchoolDay Support](mailto:support@gg4l.com).
