AI tools and client data

Is Gemini CLI safe for client data?

Short answer: Whether Gemini CLI is safe for client data turns on which plan your staff are on, which account they signed in with, and what you have told them they may put in it — not on the product itself. On Gemini Code Assist Standard (existing subscription) and on Gemini Code Assist Enterprise (existing subscription), Google says it does not train its models on code and prompts, by default. Every fact on this page is Google's own, quoted from its own pages and dated, and where we did not find a statement this page says so rather than filling the gap. Obsidian Ridge's free 30-day AI security assessment shows which AI tools your staff actually use.

Plan by plan, in Google’s own words

Gemini CLI is Google's command-line coding tool; these rows cover existing business licenses during their published retirement period.

An empty cell is not a reassurance and not a criticism. "Not found in the pages we read." means the Google pages listed under Sources, read on the dates shown, do not answer it — so there is nothing for us to repeat, and something for you to ask Google before client information goes near it.

What this means for

The duty does not change because the tool is new. What changes is where the client information ends up.

  • Law firms. A client confidence pasted into a personal account has left the firm’s control. Our law firm page sets out the duties we build evidence for; the decision here is whether a personal account may touch a client matter at all.
  • Dental and medical practices. We didn't find a BAA statement in the pages listed below; ask Google before any patient data goes in. See dental practices.
  • CPA and accounting firms. Your written information security plan has to describe the tools people actually use, not the ones you approved. See accounting firms.
  • Financial advisers. Client account data in a personal assistant is the exposure; see financial advisers.
  • Software teams. A coding assistant reads the repository and can run commands, so the question is what it can reach, not what it was asked. See what AI agents on work laptops can reach.

How to tell which version your staff use

The plan is the whole answer, and you cannot tell from the outside. Three ways to find out, in order of how much they prove.

  1. 1. Ask

    Quick, free, and incomplete. People forget the tool they installed once and the account they signed in with.

  2. 2. Look at the billing and the admin console

    This finds what the business pays for. It does not find a personal account, which is the one that matters here.

  3. 3. Look on the computers

    A tool somebody installed themselves never appears in an IT list. Obsidian Ridge’s free 30-day AI security assessment takes a quiet inventory for 30 days and shows what each tool could reach, then a CISSP goes through it with you. See the assessment, or read a sample set of findings.

Will Google sign a Business Associate Agreement for Gemini CLI?

We didn't find a BAA statement in the pages listed below; ask Google before any patient data goes in.

How do we find out which version of Gemini CLI our staff are using?

Google sells this to practices rather than to individuals, so there is no personal account to find.

What decides the answers above is which plan your practice is on and what your own administrator has switched on, both of which are in your subscription and your admin console rather than on anybody's laptop.
