User Deletion and Suppression
In keeping with Segment’s commitment to GDPR and CCPA readiness, Segment offers the ability to delete and suppress data about end-users when they are identifiable by a
userId, should they revoke or alter consent to data collection. For example, if an end-user invokes the Right to Object or Right to Erasure under the GDPR or CCPA, you can use these features to block ongoing data collection about that user and delete all historical data about them from Segment’s systems, connected S3 buckets and warehouses, and supported downstream partners.
Contact Support if you need to process more than 100,000 users within a 30 day period.
Business Plan Customers
If you use this feature to delete data, you can not Replay the deleted data. For standard Replay requests, you must wait for any pending deletions to complete, and you cannot submit new deletion requests for the period of time that Segment replays data for you.
The legacy GraphQL APIs for user deletion and suppression are deprecated. Instead, use the Segment Public API to interact with the User Deletion and Suppression system.
All deletion and suppression actions in Segment are asynchronous and categorized as Regulations. Regulations are requests to Segment to control your data flow. You can issue Regulations from your Segment Workspace, in Settings > End User Privacy
With Regulations, you can issue a single request to delete and suppress data about a user by
userId. Segment scopes Regulations to your workspace, and targets all sources within the workspace.
The three types of Regulation are:
Suppression Support and the Right to Revoke Consent
SUPPRESS regulations add a user to your suppression list by the
userId. Segment blocks suppressed users across all sources; messages you send to Segment with a suppressed
userId are blocked at the API. These messages do not appear in the debugger, are not saved in archives and systems, and are not sent to any downstream server-side destinations. Suppression does not affect device-mode destinations.
When a customer exercises the right to erasure, they expect that you stop collecting data about them. Suppression regulations ensure that regardless of how you’re sending data to Segment, if a user opts out, Segment respects their wishes on an ongoing basis and across applications.
Suppression is not a substitute for gathering affirmative, unambiguous consent about data collection and its uses.
Segment offers suppression tools to help you manage the challenge of users opting-out across different channels and platforms. Segment encourages and expects that you design your systems and applications so you don’t collect or forward data to Segment until you have unambiguous, specific, informed consent or have established another lawful legal basis to do so.
To remove a user from the suppression list, create an
Deletion Support and the Right to Be Forgotten
When you create a
SUPPRESS_AND_DELETE regulation, the user is actively suppressed, and Segment begins permanently deleting all data associated with this user from your workspace. This includes scanning and removing all messages related to that
userId from all storage mediums that don’t automatically expire data within 30 days, including archives, databases, and intermediary stores.
Segment deletes messages with this
userId from connected raw data Destinations, including Redshift, BigQuery, Postgres, Snowflake, and Amazon S3. Warehouse deletions occur using a DML run against your cluster or instance, and Segment delete from S3 by “recopying” clean versions of any files in your bucket that included data about that
Segment forwards these deletion requests to a growing list of supported partners.
Segment cannot guarantee that data is deleted from your Destinations.
Segment forwards deletion requests to supported streaming Destinations (such as Braze, Intercom, and Amplitude) but you should confirm that each partner fulfills the request.
You will also need to contact any unsupported Destinations separately to manage user data deletion.
Note that if you later UNSUPPRESS a user, the deletion functionality does not clean up data sent after removing the user from the suppression list.
The Suppressed Users tab shows an up-to-date list of actively suppressed
userIds. Segment blocks data about these users across all sources.
Suppress a new user
To create a suppression regulation and add a
userId to this list, click Suppress New User, and enter the
userId in the field that appears. Then click Request Suppression.
Segment creates a
SUPPRESS regulation, and adds the
userId to your suppression list within 24 hours.
Remove a user from the suppression list
To remove a user from the suppression list, click the ellipses (…) icon on the
userId row, and click Remove.
This creates an
UNSUPPRESS regulation, and removes the
userId from your suppression list, within 24 hours.
The deletion requests tab shows a log of all regulations with a deletion element along with status.
Click a deletion to view its status across Segment and your connected destinations.
Programmatic User Deletion and Suppression using the API
Use the Segment Public API to interact with the User Deletion and Suppression system.
Regulate User from a single Source in a Workspace
Refer to Create Source Regulation in the Public API.
Delete Object from a Cloud Source
Refer to the Create Cloud Source Regulation Public API endpoint.
Cloud Sources sync objects to Segment. As a result, Cloud Sources are regulated based on an
objectId instead of a
Before you delete the object from Segment, you should delete it from the upstream system first.
List Suppressed Users for your Workspace
Refer to List Suppressions method in the Public API.
List Deletion Requests for your Workspace
Refer to the List Regulations from Source Public API method.
