> For users who access Kiro with Pro or Pro+ tiers once they are available, your content is not used to train any underlying foundation models (FMs). AWS might collect and use client-side telemetry and usage metrics for service improvement purposes. You can opt out of this data collection by adjusting your settings in the IDE. For the Kiro Free tier and during preview, your content, including code snippets, conversations, and file contents open in the IDE, unless explicitly opted out, may be used to enhance and improve the quality of FMs. Your content will not be used if you use the opt-out mechanism described in the documentation. If you have an Amazon Q Developer Pro subscription and access Kiro through your AWS account with the Amazon Q Developer Pro subscription, then Kiro will not use your content for service improvement. For more information, see Service Improvement.
