Google says paid Gemini API prompts and responses do not improve products

When you use Paid Services, including, for example, the paid quota of the Gemini API, Google doesn't use your prompts (including associated system instructions, cached content, and files such as images, videos, or documents) or responses to improve our products

When you use Unpaid Services, including, for example, Google AI Studio and the unpaid quota on Gemini API, Google uses the content you submit to the Services and any generated responses to provide, improve, and develop Google products and services and machine learning technologies

Under “Unpaid Services”, “How Google Uses Your Data”. The same section says: “If you're in the European Economic Area, Switzerland, or the United Kingdom, the terms under "How Google uses Your Data" in "Paid Services" apply to all Services, including Google AI Studio and unpaid quota in the Gemini API, even though they are offered free of charge.” Gemini API Additional Terms of Service, kept 24 Oct 2026 · sha256 0424aabe6c15

For Paid Services, Google logs prompts and responses for a limited period of time, solely for detecting and preventing violations of the Prohibited Use Policy to maintain the safety and security of the Services, and any required legal or regulatory disclosures.

Under “Paid Services”, “How Google Uses Your Data”. The page does not state the length of the period. Some features have their own terms; for Grounding with Google Search the page says Google will store prompts, contextual information that you may provide, and output for thirty (30) days.

To achieve zero data retention, customers must take specific actions within each of these areas:

Under “Customer data retention and achieving zero data retention”. The same page says: “Zero data retention may not be possible when using some Advanced AI features.” and, for Grounding with Google Search and Google Maps, “There is no way to disable the storage of this information”.

Data stored at rest in the customer selected location remains at rest in that location, independent of the Gemini Enterprise Agent Platform endpoint called by that customer's request.

The page adds: “Requests submitted to a global endpoint may be processed in any Google Cloud location around the world, and therefore don't provide any data residency guarantees.” Data residency, kept 26 Oct 2026 · sha256 dbd4fd892d3f

Quotas have default values, but you can typically request adjustments. System limits are fixed values that can't be changed.
