The Gemini API stores your requests by default: what store=true means

Since October 26, 2026, the Gemini API stores your requests by default in new paid projects. The setting is called store, it is on by default (store=true), and it saves the prompt, the response, and the context from earlier turns. You can switch it off per request with store=false.

What the Gemini API saves when store is on

When you create a new paid project, Google keeps what you send to the Gemini API without you asking for it. According to the Gemini API changelog from October 26, 2026 and the Logs and Datasets documentation, what gets saved includes:

• The prompt you sent.
• The model's response.
• The context from earlier turns of the conversation.

The rule is simple: whatever you don't turn off, stays saved.

How long stored requests are kept

Saved requests are kept for 55 days by default. You can also configure retention of 7, 14, or 28 days. One exception is worth remembering: anything saved in a dataset never expires.

How to turn off request storage in the Gemini API

There are two ways:

1. Per request: add store=false to the call. That setting overrides the project configuration.
2. From the panel: in the API log settings in Google AI Studio.

Projects that already existed before the change keep their setting; the change applies only to new paid projects.

How to apply it in your business?

If your team uses the Gemini API with customer data, these steps help you avoid finding out by surprise in an audit:

• Check when each of your Gemini projects was created: only new paid projects store by default.
• Decide what you want to keep from your customers and what you don't.
• If you don't need the log, turn storage off per request with store=false or from the log settings.
• Remember that anything saved in a dataset never expires, so handle it carefully.

One important note: the documentation doesn't say whether saved data is used for training models, so we can't claim anything about it. We also didn't review what Google does with datasets you share with them.
