If you turn off Gemini's Keep Activity and think that Gemini Live will leave no records at all, this understanding is not accurate. Closer to the official statement, these conversations don't usually appear in Gemini Apps Activities, but they may still remain in your account for up to 72 hours to provide service and process feedback.
This is also where many people misjudge. There is no history visible on the interface, which does not mean that the backend is completely deleted instantly. Google writes in the help documentation quite straightforwardly: when the Keep Activity is turned off, the relevant conversation will not enter the Gemini Apps Activity, but the data may be retained for a short period of time for service operation and feedback processing.
So if you are particularly concerned about privacy, separate these three concepts first:
1. Will it be displayed in the Activity history?
2. Will it be retained for a long time as a personal visible history?
3. Will it be temporarily stored for a short period of time for system processing?
After Gemini Live turns off history, what usually changes are the first two layers, not "immediately without a trace" in the absolute sense. This is why many people say, "I am obviously closed, why is the official still mentioning 72 hours", which is actually not contradictory.
What you really do depends on the goal. If your goal is to "don't want to see this conversation in an activity later", turning off Keep Activity works. If your goal is to "keep no short-term service records at any level", then don't think of it as an absolute switch, but rather judge the risk boundary according to Google's current retention rules.
Also, don't confuse Gemini Live with regular text history. When Live involves audio, transcription, file, or screen sharing, the data link is more complex. The more you use it as a real-time assistant, the more you need to figure out what records, displays, and short-term retention are.
So the answer is simple: Gemini Live usually doesn't go into your activity history when you turn off Keep Activity, but that doesn't mean you have zero retention at the platform level. For people with high privacy requirements, what is really useful is to see this boundary clearly, not just to see if there is a record on the interface.
