In short. Delete every relevant Gemini chat and then disconnect the connected app; either step alone leaves another source of the information available.
Definition: No. Google documents a combined procedure for information that Gemini remembered from a connected app: delete every chat containing the information, then disconnect that app. Disconnecting alone can leave the information available through a past chat.
Key facts
- Google's Personal Intelligence help says to delete all chats containing the information from Gemini Apps Activity or Recent chats, then disconnect the app.
- The same help page says that disconnecting alone may leave Gemini able to use information in a past chat, while deleting chats alone may leave the information available in the connected app.
- Google's past chat memory help says there might be a short delay before Gemini stops using a deleted chat to personalize responses.
- Google's Connected Apps privacy explanation says disconnecting an app or deleting data in it does not delete data from Gemini Apps Activity.
- Google's recent chats help says deleting a recent or pinned chat also deletes its related activity from Gemini Apps Activity.
What does disconnecting an app change?
Personal Intelligence uses Connected Apps as a source of information for personalized Gemini responses. The Personal Intelligence documentation says the Connected Apps settings can connect or disconnect services such as Google Workspace, Google Photos, Search services, and YouTube. Disconnection stops that app from being used through the connected-app connection for this purpose.
Disconnection has a separate scope from chat history. Google's Connected Apps privacy explanation says that choices about Connected Apps do not change the Memory setting, so past chats can continue to personalize the experience while Memory remains on. It also says that public websites and videos from Google Search and YouTube can remain available even when those services are not connected.
What must be deleted as well?
The documented removal sequence has two parts. First, delete every Gemini chat containing the information from Gemini Apps Activity or Recent chats. Second, disconnect the app that supplied the information. Google gives both steps because a past chat can retain a route to the information, while the connected app can provide the information again if the chats alone are removed.
For a computer, the settings path for the second part is:
Settings & help > Personal Intelligence > Connected Apps
The past chat memory documentation says that deleting a chat may be followed by a short delay before Gemini stops using it to personalize responses. The recent chats documentation adds that deleting a chat also removes content created in that chat, such as Canvas documents and apps, together with the related activity from Gemini Apps Activity.
What remains separate from this procedure?
Deleting a Gemini chat and disconnecting an app affect Gemini's activity and connection settings. Google's Connected Apps privacy explanation says that deleting Gemini Apps Activity does not delete data in other services. Deleting or updating the original data in a connected app can also take days to affect the Gemini experience.
The procedure is therefore a way to remove the information from the relevant chats and stop the connected-app route. It is not a single deletion action across every Google service. The current Google help pages do not specify a fixed time for every affected response to change.

FAQ
If I only disconnect the app, can Gemini use the old information?
Yes. Google says that Gemini might still use the information if it is present in a past chat, so you should also delete every relevant chat.
If I delete the chat, does the connected app data disappear?
No. Google says that deleting Gemini Apps Activity does not delete data in other services. Disconnect the app as the second part of the procedure.
Can I use this procedure with a work or school account?
Google says that a Workspace administrator controls Gemini Apps Activity for work or school accounts. You may be unable to delete chats or change retention settings.
