How Google Messages improves suggestions with federated technology

With the Help improve messages setting turned on, federated technology works with your messages, other interactions and machine-learning models to improve features for the Google Messages app and ensure that none of your message content or data is sent to Google.

The Google Messages machine-learning models form the foundational technology driving the smart and assistive features of the app. These models continuously improve through fine-tuned adjustments without sending your conversation content to Google. First, Google Messages sends summaries of recent model changes to Google servers. Next, these summaries are combined with summaries from thousands of other devices. Finally, from these combined summaries, the improved models provide smart features that work better for everyone. These combined summaries can't reveal your conversations or content to Google or anyone else.

Your interactions in Google Messages, including with smart features, also indirectly inform the Google Messages machine-learning models. Based partly on your interactions, these machine-learning models adjust the smart features to provide better, more personalised experiences for you. Federated technology ensures that only the adjustments to the machine-learning models and the aggregated information, and none of your content, are sent to the Google federated technology server.
