# How to Use the Attendee Data Anonymization Feature
## The Attendee Data Anonymization feature helps event organizers protect participant privacy by allowing them to manually anonymize selected attendee data after the event.
Once anonymized, this data is permanently replaced with masked or randomized values and **cannot be restored**.
This is useful for events where sensitive personal information must be purged after a specific period for compliance or internal data handling policies.
#### **Accessing the Anonymization Settings**
1. Navigate to **Form Builder \> Settings** for the attendee registration form.
2. Scroll down to the **Data Anonymization** section.
3. Enable the toggle labeled **“Enable Attendee Data Anonymization.”**
#### **Marking Fields for Anonymization**
Once anonymization is enabled:
1. Go to **Form Builder \> Configure Form Fields**.
1. Click the pencil icon on the field you want to anonymize.
1. In the **Advanced Settings** panel, enable the toggle **“Anonymize this field.”**
****
You can mark multiple fields for anonymization. Only these selected fields will be affected when anonymization is triggered.
#### **Triggering Anonymization Manually**
1. Return to **Form Builder \> Settings \> Data Anonymization**.
2. Click the **“Anonymize Now”** button.
#### **How Anonymization Works**
Fields marked for anonymization will be replaced with anonymous values:
| **Field Type** | **Example Before** | **Example After** |
| --- | --- | --- |
| Name | John Doe | Anon\_8273 |
| Email | john.doe@email.com | anon8273@anonymous.com |
| Phone | +1 234567890 | XXXX |
Fields **not** marked for anonymization (e.g., company name) remain unchanged.
#### **Viewing Anonymization History**
After anonymization is triggered, a log entry will be created.
Below the anonymization settings, you can view the **Anonymization History**, which includes:
- **Date & Time** of anonymization
- **Triggered By** (the backend user who performed the action)
- **Trigger Type** (Manual)
#### **Email Notification**
Once anonymization is successfully completed, the system sends an email notification to the backend user who initiated the action.
#### **Important Notes**
- Anonymization is a **manual** process and must be triggered intentionally by the event organizer.
- Once data is anonymized, it **cannot** be recovered.
- Ensure the correct fields are selected before triggering anonymization.
