By default, Google stores this information with your Google Account for up to 18 months. To help with quality and improve our products, human reviewers read, annotate, and process your Bard conversations. We take steps to protect your privacy as part of this process. This includes disconnecting your conversations with Bard from your Google Account before reviewers see or annotate them. Please do not include information that can be used to identify you or others in your Bard conversations.
If you want to use Bard without saving your conversations to your Google Account, you can pause saving your Bard activity. You can review your queries or delete your Bard conversations from your account at
myactivity.google.com/product/bard. Bard conversations that have been reviewed or annotated by human reviewers are not deleted when you delete your Bard activity because they are kept separately and are not connected to your Google Account. Instead, they are retained for up to three years.
--不影响使用的情况下，可以关闭 bard activity 功能。如果之前的历史活动 被人工审核或注释的话，删除也没用，数据会保存三年
Even when Bard activity is off, your conversations will be saved with your account for up to 48 hours. This allows us to provide the service and process any feedback. This activity will not show up in your Bard Activity.
即使关闭 Bard 活动，您的对话也会在您的帐户中保存长达 48 小时。这使我们能够提供服务并处理任何反馈。此活动不会出现在您的 Bard activity 中。
