We use the Gemini Developer API with a billed API key (paid tier) from Google AI Studio, for a small business app that processes sensitive documents. We would like to enable Zero Data Retention (ZDR) for our project, specifically opting out of the abuse-monitoring prompt logging, so that prompts/responses and identifiable metadata are cleared prior to logging, as described in the official docs: https://ai.google.dev/gemini-api/docs/zdr
Our integration already meets the ZDR requirements: no explicit context caching (cached_content), no File API persistence, no Grounding with Google Search/Maps, and no Interactions API state storage.
Questions:
What is the exact process to request ZDR approval for a Gemini Developer API project? Is there a request form, or is invoiced billing required?
Is ZDR available for small / non-enterprise paid-tier accounts on the Developer API?
I can provide the project ID privately if needed. Thank you!
Following up — is there any official guidance from the Google team on the ZDR request process for Developer API projects? Still hoping for a reply. Thank you!
Thank you for getting back to me, and thank you for the DM.
Yes, we are currently considering migrating to Vertex AI, as it was also recommended to us by the Google Cloud sales team. We understand that Vertex AI does not use customer data for training and offers stronger data governance, which fits our requirements as a professional firm handling confidential client documents.
Before we proceed, I would appreciate your guidance on two points:
On Vertex AI, is there an official process to request an exemption from abuse-monitoring data logging (i.e., zero data retention)? If so, could you point me to the application route or documentation?
Is there anything else we should be aware of when migrating from the Gemini Developer API to Vertex AI (e.g., differences in API endpoints or model availability)?
We’re in the same boat and would really appreciate an official answer. We run the Gemini API (paid tier) in production via the Developer API. We’d like to enable Zero Data Retention (opt out of abuse-monitoring prompt logging). Could someone from the team confirm:
Can ZDR be enabled on an existing Gemini Developer API project as-is?
Is invoiced billing (or an enterprise agreement) required to qualify?
If the Developer API can’t support ZDR, is Vertex AI the recommended path — and where’s the exact opt-out request?
+1 and our company signed up for paid tier 1 after seeing that we can enable ZDR for projects created using AI Studio. If ZDR requires Vertex AI, then Google’s documentation is misleading as it clearly states
“When your request for ZDR for a particular project is approved, all user content (prompts and responses) and identifiable metadata (such as IP addresses and Google Account IDs) are cleared prior to logging.”
@Mustan_lokhand can you please DM me as well? Appreciate it!
Hi, I would like to request Zero Data Retention for my paid Gemini Developer API project, as described at ai.google.dev/gemini-api/docs/zdr.
Project number: 7702887203..
Context: We are an EU-based education service (slohujeme.sk) that helps teachers assess handwritten school essays. All uploads are anonymized before they reach the API, but since the content originates from school pupils (children), ZDR is important for our GDPR posture and for the data processing agreements we sign with schools.
Our integration already meets every technical ZDR precondition listed in the documentation:
no Grounding with Google Search or Google Maps,
no Interactions API (stateless generateContent calls only),
no Live API,
no File API — all images are sent inline within the request,
no explicit context caching (cached_content).
The abuse-monitoring logging exemption is therefore the only remaining piece. Could you please let me know the request process, or process the approval for the project above? Happy to provide any additional information.
We have the same requirement for a paid Gemini Developer API project in the EEA.
We created a dedicated paid Google Cloud project specifically for private business data processing and would like to request Zero Data Retention (ZDR) for it. Developer logging is disabled, and the intended path will use store:false with no Grounding, Files API, explicit caching, persistent Interactions, or Live session resumption.
Could you please DM me with the information required to submit our project for ZDR approval? I can provide the Google Cloud Project ID privately.
