Title: Data deletion request — Free tier data processed before billing was enabled

Body:

I am requesting deletion of data submitted to the Gemini API under
the Free/Unpaid Service tier before I enabled billing on my project.

Account: y...@gmail.com
Project number: 491727698..
Project name: graphify
API key name: graphify-gemini
Date of the unpaid-tier request: 2026-09-02 (before billing activation,
same day)
Nature of the data: personal notes/documents (Markdown files) submitted
via the Gemini API for semantic text extraction

I was not aware at the time of the request that unpaid-tier usage may
be used to improve Google products and reviewed by human annotators.
Billing was enabled on the same project shortly after this request,
and all subsequent requests have been made under the Paid Service tier.

I would like to request:

  1. Deletion of the specific unpaid-tier request(s) made on 2026-09-02
    under this project/API key, to the extent technically possible.
  2. Confirmation of whether this data has already been used in any
    training pipeline, and if so, what options exist.

Thank you for your assistance.

Hello @Yoontrade ,

Under the Gemini API Additional Terms of Service, content submitted under the unpaid tier is disconnected from your Google Account, API key, and Cloud project before it is processed or reviewed. Because this data is de-identified upon ingestion, specific unpaid requests cannot be linked back to your project or deleted.

For requests made after enabling billing on your project, they are processed under the Paid Services terms, where Google does not use your prompts or responses to improve products or train models.
