Gemini CLI

If you use this, all of your code data will be sent to Google. From their terms:

https://developers.google.com/gemini-code-assist/resources/p...

When you use Gemini Code Assist for individuals, Google collects your prompts, related code, generated output, code edits, related feature usage information, and your feedback to provide, improve, and develop Google products and services and machine learning technologies.

To help with quality and improve our products (such as generative machine-learning models), human reviewers may read, annotate, and process the data collected above. We take steps to protect your privacy as part of this process. This includes disconnecting the data from your Google Account before reviewers see or annotate it, and storing those disconnected copies for up to 18 months. Please don't submit confidential information or any data you wouldn't want a reviewer to see or Google to use to improve our products, services, and machine-learning technologies.

It's a lot more nuanced than that. If you use the free edition of Code Assist, your data can be used UNLESS you opt out, which is at the bottom of the support article you link to:

"If you don't want this data used to improve Google's machine learning models, you can opt out by following the steps in Set up Gemini Code Assist for individuals."

and then the link: https://developers.google.com/gemini-code-assist/docs/set-up...

If you pay for code assist, no data is used to improve. If you use a Gemini API key on a pay as you go account instead, it doesn't get used to improve. It's just if you're using a non-paid, consumer account and you didn't opt out.

That seems different than what you described.
