Google 更新隐私政策：Gmail 与相册数据若共享给其他服务或将用于广告
Updated Google privacy policy says your Gmail might be used for advertising
Google 于 10 月 16 日更新了隐私政策，修改了原先承诺不对 Gmail、Drive 或 Photos 内容投放个性化广告的绝对限制。新条款补充说明，若用户选择将这些服务的数据提供给支持个性化广告的其他 Google 服务，相关内容就可能参与广告投放。
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.
