Who is affected
Developers and businesses creating new projects on the Gemini API; the source does not specify any sector or scale restriction.
What it means for your business
For businesses using the Gemini API, this means requests from newly created projects are now logged and stored automatically unless they opt out themselves.
What to do
Businesses creating a new Gemini API project should set store=false on individual requests, or disable Generate Content API logging in the Settings panel of the Logs and Datasets dashboard, if they do not want requests stored.
When it takes effect
The change is dated October 26, 2026; no separate effective date is given in the source.
