What is more, Google emphasizes a crucial point: you should avoid sharing messages with Bard that you wouldn’t want a reviewer or Google to access. The description specifies that while reviewed data is detached from the user’s account, it remains stored for up to three years.
However, Google’s throwing in an option to turn off, manage, and delete your Bard Activity. If you decide to flip the Bard Activity switch off, your chats will only be saved for a short 72 hours.
As of now, the feature still does not work on Google Messages. Traces that Bard is coming to the messaging app were discovered almost a year ago, and now it appears that its integration is finally nearing completion.
