  • Article

Important

LUIS will be retired on October 1st 2025 and starting April 1st 2023 you will not be able to create new LUIS resources. We recommend migrating your LUIS applications to conversational language understanding to benefit from continued product support and multilingual capabilities.

Delete customer data to ensure privacy and compliance.

Summary of customer data request features​

Language Understanding Intelligent Service (LUIS) preserves customer content to operate the service, but the LUIS user has full control over viewing, exporting, and deleting their data. This can be done through the LUIS web Azure portal or the LUIS Authoring (also known as Programmatic) APIs.

Note

This article provides steps about how to delete personal data from the device or service and can be used to support your obligations under the GDPR. For general information about GDPR, see the GDPR section of the Azure Trust Center and the GDPR section of the Service Trust portal.

Customer content is stored encrypted in Microsoft regional Azure storage and includes:

  • User account content collected at registration
  • Training data required to build the models
  • Logged user queries used by active learning to help improve the model
    • Users can turn off query logging by appending &log=false to the request, details here

To enable active learning, users' logged utterances, received at the published LUIS endpoints, are stored in Microsoft Azure operated by 21Vianet geographies:

With the exception of active learning data (detailed below), LUIS follows the data storage practices for regional services.

With the exception of active learning data (detailed below), LUIS follows the data storage practices for regional services.

The luis.azure.cn portal and China Authoring (also known as Programmatic APIs) are hosted in Azure's China geography. The https://luis.azure.cn portal and China Authoring (also known as Programmatic APIs) support deployment of endpoints to the Microsoft Azure operated by 21Vianet geographies.

When deploying to these Azure geographies, the utterances received by the endpoint from end users of your app will be stored in Azure's China geography for active learning.
