If you use Gmail, you need to be aware of an important change that’s quietly rolling out. Reportedly, Google has recently started automatically opting users in to allow Gmail to access all private messages and attachments for training its AI models. This means your emails could be analyzed to improve Google’s AI assistants, like Smart Compose or AI-generated replies. Unless you decide to take action.

The reason behind this is Google’s push to power new Gmail features with its Gemini AI, helping you write emails faster and manage your inbox more efficiently. To do that, Google is using real email content, including attachments, to train and refine its AI models. Some users are now reporting that these settings are switched on by default instead of asking for explicit opt-in.
