The email states that Gemini will be able to "help you use" the above apps regardless of whether Gemini Apps Activity is enabled, though users can turn these features off in the Apps setting page. The update is set to roll out automatically beginning on July 7.
The update appears to allow you to access Gemini's functionality in these apps even if you have Gemini Apps Activity turned off, so you don't lose anything by declining to have your chats stored and used in various ways.
How to disable Gemini Apps Activity
Gemini Apps Activity is enabled by default for users over 18. You can turn it off in the Gemini app by tapping your profile picture or initial followed by Gemini Apps Activity > Turn off > Turn off or Turn off and delete activity. Note that Google still stores your Gemini interactions on its servers for up to 72 hours when Gemini Apps Activity is off, but the activity won't appear in your account.
