# Data Privacy and Protection

> Fireblocks does not store or process any client Personal Identifiable Information (PII). To achieve this, the customer is required to strictly use anonymized tokens, such as  (UUID) to reflect client data. These anonymous tokens are mapped internally by the customer to actual client identifiers stored on the customer's end.

Since the customer processes and manages its wallet infrastructure using the Fireblocks Console or Fireblocks API, these anonymous tokens should be used when using the Fireblocks REST API endpoints. The following table lists the relevant fields that allow persistent information to be stored in Fireblocks–for which the anonymous tokens should be used.

| API Endpoint    | Method                                                                                                                                                 | Parameter     |
