Deleting users

Learn more about how user deletions work within Knock and how deletion can help with data privacy controls.

Knock provides a programmatic user deletion API that you can use to hard delete users and the data associated with users. This can be especially useful in fulfilling GDPR right-to-be-forgotten requests.

What data is deleted for a user?

When a user is deleted in Knock, we will hard delete:

All system and custom properties set on the user
All preferences associated with the user
All channel data associated with the user
All subscriptions associated with the user
All schedules associated with the user
All messages sent to that user, including the content of those messages and any debugging events associated
All activity associated with a user, including the workflow run logs the user was a recipient of

Note: deletion requests can take up to 10 minutes to process. During this time, you may still see some data associated with the user.
