Gmail users who are concerned about how Google handles their data should look for the toggles for smart features in the settings menu. The fine print states that the AI functionality, which includes many features, is intended mainly for personalizing the user experience. However, some remain suspicious given Google's efforts to insert Gemini into all of its products.
The settings menu states that users who enable smart features agree to let Google use their information and activity to personalize the experience. Malwarebytes and blogger Dave Jones interpreted the wording to mean that the company is training AI with user content, but Google insists this is inaccurate.
