Google 更新隐私政策，Gmail 内容或可用于广告个性化
Updated Google privacy policy says your Gmail might be used for advertising
Google 于 10 月 16 日更新隐私政策，删除了不会基于 Drive、Gmail 或 Photos 内容展示个性化广告的明确承诺，改为若用户将这些服务的数据开放给其他支持个性化广告的 Google 服务则可能使用。文章指出 Google 2026 年初发布的 Personal Intelligence 可跨应用汇集数据交给 Google AI 产品，为数据用于广告留出了通道。
Using Google's products and services has always been fundamentally precarious—doing so gives the world's largest advertising company a lot of juicy personal data. Google has long said it won't use the sensitive data from products like Gmail, Drive, and Photos for ad personalization, but a change to the company's privacy policy appears to dismantle that firewall.
On October 16, Google issued an update to its privacy policy, spotted by Android Authority. The ad personalization section used to include a clear limit on data from certain apps. "We don’t show you personalized ads based on your content from Drive, Gmail, or Photos," the document said. Now, Google has updated it with the following language.

This equivocation opens the door to using data from apps like Gmail and Photos in ads when it's shared with other Google services, and it just so happens Google has a mechanism for doing that, with Personal Intelligence. The company released Personal Intelligence in early 2026, allowing users to hand data from multiple apps to Google AI products. 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.
