Mountain View-based Google updated its privacy policy, effective Oct. 16, to say data from apps such as Gmail and Photos may be used for ads if users choose to make it available, Ars Technica reports.

Why it matters: Gmail content has long been off-limits for ad targeting. The new language ties to Personal Intelligence, which lets Gemini and Search draw on connected Google apps.

What Google says

  • Ads are "not based directly" on the contents of your inbox, connecting apps is opt-in, and sensitive information is excluded, Google said in a statement.
  • Users can turn it off in Gemini's Personal Intelligence settings, or under Search personalization in Connected Content Apps, The Hacker News reports.
  • The feature is not available in the European Economic Area, Switzerland, the U.K. or Nigeria.

The change comes as rivals add ads to AI products. OpenAI's ads now run in 89 countries.
