# Data residency and PII

> Where Stigg stores data, including personally identifiable information (PII), and how to control what's sent

## Does Stigg store PII?

Sending Personally Identifiable Information (PII) to Stigg, such as a customer's name and email address, is **optional**, but is beneficial from a user experience perspective for easy identification of customers on the Stigg platform.

When PII is not sent to Stigg, identification of customers is done using the customer ID.

## Where is data stored?

Stigg's infrastructure runs on AWS. Our primary region for data residency is **us-east-2 (Ohio)**, with multi-region failover to **us-west-2 (Oregon)** in case of a regional incident.

If PII is sent to Stigg, it's stored securely in this managed infrastructure and served via Stigg's globally replicated CDN for [improved latency](../high-availability-and-scale/accessible-from-everywhere).

To support global performance and availability, the CDN replicates mission-critical data from the U.S. to additional regions:

* **EU**: Germany
* **APAC**: Mumbai, India

This replication supports low-latency access for customers operating in Europe and Asia, and is relevant for organizations evaluating data residency and geopolitical considerations as part of their compliance requirements.
