Where Google's pages were unclear

Where the pages were unclear

  • Google's Gemini pages give no time period for removing a chat after you delete it; one page only says there may be a short delay before Gemini stops using it for memory.
  • Google's account-deletion page does not mention Gemini chats and says data is removed 'after a certain amount of time', with no exact period.
  • Gemini's own opt-out is not a separate training switch: it is the Keep Activity setting, which also turns off chat history and memory.
  • The phone app route to Keep Activity differs: Menu > your profile picture > Gemini Apps Activity.
  • The export page does not say what file format the chats are in.
