Google Privacy Policy Update Opens Door to Using Gmail Data in AI and Ads

Google updated its privacy policy on October 16, removing language that said it would not show personalized ads based on content from Drive, Gmail, or Photos. The revised wording allows sensitive app data to inform ads when shared with other Google services. The report links this change to Google's Personal Intelligence feature, released in early 2026, which lets users feed data from multiple apps into Google AI products. The piece frames this combination as a privacy concern for users.

The idea is that the added context from your existing data will lead to better AI answers, but it's also proving to be a privacy minefield.
