What Google Gemini actually does with your data

Google's chatbot, one tap away on Android phones, in Chrome and in search. On a personal account, the training switch is on until someone finds it.

What AI is in it?

  • The chat itself. Whatever someone types, pastes or uploads goes to Google's servers to be answered, the same shape as ChatGPT.
  • Everywhere Google already is. Gemini is built into Android phones, Chrome and Google search, so staff meet it without ever deciding to visit an AI tool. The assistant on a work phone is the same Gemini described here.

Does your data train AI models?

Depends on the account.

On personal accounts, with the Keep Activity setting on, which is the default, Google says it uses your activity to provide, develop and improve its services, "including training generative AI models". Turn Keep Activity off and future chats are not used for training, unless you send feedback.

Two details deserve daylight.

A subset of chats goes to human reviewers to improve Google's services, and reviewed chats are kept for up to three years. And Google's own privacy hub says, in its own words: "Please don't enter confidential information that you wouldn't want a reviewer to see or Google to use to improve our services." That sentence, from the vendor, is your staff rule written for you.

Work and school accounts under Google Workspace sit under different terms, which the Google Workspace entry covers.

Where is your data processed?

Google LLC for UK users.

For people in the UK, Gemini is provided by Google LLC, the American company; Google Ireland covers the EEA and Switzerland, and since Brexit that is not us.

Google does not publish a per-chat processing location. Even with Keep Activity off, chats are retained for 72 hours, and Google still uses them to respond and to protect its services.

What changes between free and paid?

The account is the story.

As with ChatGPT, the tier that matters is not free versus paid, it is personal versus organisational.

A staff member chatting to Gemini on a personal Google account is a consumer, and your organisation has no contract, no visibility and no say in the settings. Google Workspace accounts move the same chat under terms your organisation actually holds.

Can your organisation turn it off?

Not for personal accounts.

If staff use personal Google accounts, there is nothing for your organisation to control: the settings belong to the individual, including Keep Activity. Google Workspace gives administrators actual controls, which is the subject of its own entry.

What does this mean for the people you support?

Gemini is closer to hand than the other chatbots because it lives on the phone and in the browser staff already hold, which means it gets used without anyone deciding to use an AI tool.

A support worker asking their Android phone to tidy up case notes is having that conversation with Google, on consumer terms, on a device your organisation may not even manage.

What to check this week

  1. Find the setting on personal accounts. Anyone using Gemini for anything work adjacent should open Gemini's settings and check Keep Activity, and switch it off if they would not want the chat used for training. It is on by default.
  2. Adopt Google's own sentence as the rule. "Don't enter confidential information you wouldn't want a reviewer to see." Put it in your AI policy verbatim, credited to Google. Nobody can argue with the vendor's own advice.
  3. Give regular users a proper home. If people rely on it, a Google Workspace plan with Gemini, or a private alternative, puts the use under an agreement your organisation holds rather than the member of staff's personal account.

Everything above is my plain English reading of what Google publishes. The originals:

Vendors change these documents quietly and often. If you spot something out of date, email me and I'll re-verify the entry.

What this page cannot tell you

This page can tell you what Google Gemini does with what goes into it. It cannot tell you what goes into it at your organisation, and that is the half that matters.

The answers above kept splitting on whose account it is, and the free personal kind is invisible to you: it shows up in no system you run and on no bill you pay, and nobody declares it on a survey.

So the next step is not a setting. It is finding out what is being pasted, by whom, from which accounts, which is what a discovery is for. And your team needs a rule clearer than "be careful", which my free Charity AI Policy Generator writes with you in a few minutes.

See your whole toolkit at once

This page covers one tool. The AI Exposure Report Generator covers your toolkit: tick the tools your charity uses and get one report showing what the AI inside each of them does with your data, as a Word document you can table at your next meeting. Free, and nothing you tick leaves your browser.

Start with a discovery

The first step is always the same, and it's a small one: a short, fixed-price discovery. Over a couple of weeks I work out what your team is already doing with AI, where your data actually lives, and the one thing worth building first. You get a written report and a call to talk it through, with no obligation to go further. It's genuinely useful on its own, whether or not we end up building anything.

Here's a sample, laid out exactly as the real one is delivered.

For context: I work mainly with UK charities and non profits, with chief executives, operations and finance directors, programme leads, and the people who look after data and IT. Respectfully, I don't work with recruitment or development agencies.
