Delete user data

This document explains how you can delete data associated with a given user ID using the Google Analytics User Deletion API. This tool is one of several tools available to help you safeguard your data.

Important: The User Deletion API doesn't remove data from reports based on previously aggregated data, such as user counts in the audience overview report, or from other places you may have exported data to, such as BigQuery.

For more details, see the reference documentation.

You can use Firebase projects or Google Analytics properties to send User Deletion API requests. The https://www.googleapis.com/auth/analytics.user.deletion OAuth 2.0 scope is required for the requests in this guide.

Send a deletion request

Use the upsert method to request the data deletion for a given user. The upsert method takes a userDeletionRequest as its only parameter.

Specify the user whose data you want to delete by setting one of the IDs inside the id.userId field. The type of the ID must be specified inside the id.type field.

Here's a list of supported user ID types:

• CLIENT_ID: Google Analytics client ID (only supported when propertyId field is set).
• USER_ID: Google Analytics User ID (only supported when propertyId field is set).
• APP_INSTANCE_ID: Firebase application instance ID (only supported when firebaseProjectId or propertyId field is set).

Each data deletion request processes only the ID submitted in that request.

If you have multiple IDs associated with the same user, you must submit separate deletion requests for each ID associated with that user. If you Use BigQuery export, you must also process your own deletions there.

Deletion timeline

The upsert method returns a User Deletion Request Resource with the deletionRequestTime field set. The deletionRequestTime field tells you the time at which the deletion request was received by Google Analytics.

Once deletion is requested, data associated with the user ID will be removed from the Individual User Report within 72 hours, and then deleted from Analytics servers during the next deletion process. Deletion processes are scheduled to occur every two months. If you have exported the user data outside of Google Analytics, we recommend you delete it there first.
