Google has begun rolling out a feature that enables its Gemini AI chatbot to automatically remember key personal details and preferences from previous chats, unless users opt out. However, this builds upon earlier functionality where memory could only be activated on request.

The update is enabled by default on Gemini 2.5 Pro in select countries and will be extended to the 2.5 Flash version later. Users can turn off the setting under Personal Context in the app to deactivate it.

Alongside auto-memory, Google is introducing Temporary Chats, a privacy tool for one-off interactions. These conversations aren't saved to your history, aren't used to train Gemini, and are deleted after 72 hours.

Google is also renaming 'Gemini Apps Activity' to 'Keep Activity', a setting that, when enabled, lets Google sample uploads like files and photos to improve services from 2 September, while still offering the option to opt out.
