PII Viewer for Google Analytics

The simple and easy way to view personally identifiable information (PII) in Google Analytics.
Sending personally identifiable information (PII) to Google Analytics is strictly prohibited, but sending a unique user ID is permitted. This extension allows you to map the user ID stored in Google Analytics to PII such as name and email address stored locally.

Rather than building your own custom integration to map this data together, you can simply reference a locally stored CSV file and let this extension do the hard work. This means that you comply with the privacy policy, but get to understand your visitor data.
