Google 更新私隱政策，Gmail 內容或用於廣告個人化
Updated Google privacy policy says your Gmail might be used for advertising
Google 於 10 月 16 日更新私隱政策，移除了原先明確表示不會根據 Drive、Gmail 或 Photos 內容展示個人化廣告的限制。新措辭可能容許在相關資料與其他 Google 服務共享時，將 Gmail、Photos 等應用程式資料用於廣告。
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.
