Paid and unpaid are data-treatment categories
| Route | Google’s public terms | Legal-team decision |
|---|---|---|
| AI Studio or unpaid API quota | Content and responses may be used to provide, improve and develop products; human reviewers may process them. | Do not submit sensitive, confidential or personal information. |
| AI Studio with eligible billing access or Workspace enterprise account | The terms define this access as a paid service even when the interface is offered without a separate charge. | Preserve the account and Cloud-project evidence. |
| Gemini API through an active billing project | Prompts and responses are not used to improve products and are processed under the named DPA. | Still review logging, region, features and the operative customer agreement. |
Region changes the account rule
Google states that API clients made available to users in the EEA, Switzerland or the United Kingdom may use only paid services. The same terms say the paid-services data-use provisions apply to all services for users in those regions. That is a contractual scope statement, not a conclusion about a firm’s professional duties or privilege.
Verify the billing project in the request path
A billing account elsewhere in the organization does not establish that a specific API call is paid. Record the Cloud project, billing state, API key or service identity, model ID, region and timestamp. Test from the same environment that will process approved material.
Paid does not automatically mean ZDR
Google says paid-service prompts and responses are not used to improve products, while limited logging can still support abuse prevention and legal or regulatory disclosures. Separate Gemini documentation describes project approval and feature-specific retention. Keep training use, logging, stored files, caches, conversation state and grounding as distinct fields.
Minimum approval packet
- Name the Cloud project and verify active billing.
- Confirm region and permitted users.
- List enabled features, storage and grounding.
- Attach the current terms, DPA and customer-specific documents.
- Run a de-identified trace and inspect logs.
- Assign the human reviewer and output system of record.
FAQ
Does Google use unpaid Gemini API content to train or improve products?
Google’s terms say unpaid-service content and responses may be used to improve products and machine-learning technologies, and human reviewers may process them.
Does paying for Gemini API guarantee zero data retention?
No. Paid status changes the product-improvement rule, but logging and feature-specific storage must be reviewed separately.
What makes Gemini API usage a paid service?
Google defines Gemini API access as paid when the request uses a Cloud project associated with an active billing account.
