Is It Safe to Put Company Data into ChatGPT, Claude or Gemini?

Whether it is safe to put company data into ChatGPT, Claude or Gemini depends on three things: which plan you are signed in to, how its privacy settings are set, and what kind of data it is. A personal account with default settings is a different situation from a business workspace your employer has set up.

The short version: on all three providers, business and API plans do not use your data to train models by default, according to their own help pages. Consumer accounts work differently, and each provider has a setting that changes what happens. Below is what each provider’s official pages say, the exact settings to check, and a simple way to decide what can be pasted. Last verified: November 1, 2026.

What each provider says

OpenAI (ChatGPT)

• Personal accounts (Free, Plus, Pro): OpenAI’s data controls article says data sharing for model improvement is enabled by default. Turning off Improve the model for everyone under Settings → Data Controls means new conversations are not used to train OpenAI’s models. Turning it off does not delete your saved chats.
• ChatGPT Business, Enterprise, Edu and the API: OpenAI says that by default it does not use inputs and outputs from these products to train its models (ChatGPT Business privacy).

Anthropic (Claude)

• Consumer accounts (Free, Pro, Max): Anthropic’s Privacy Center says chats are used to improve Claude when you choose to allow it, when conversations are flagged for safety review, or when you otherwise opt in. It also says Incognito chats are not used to improve Claude, even if model improvement is enabled.
• Retention: with model improvement on, chats may be kept in de-identified form for up to 5 years in training pipelines. Deleted chats are removed from your history immediately and from back-end storage within 30 days (How long do you store my data?).
• Commercial products (Claude for Work, the API): “By default, we will not use your inputs or outputs from our commercial products” to train models, unless you report feedback or bugs or otherwise choose to allow it (commercial training article).

Google (Gemini)

• Gemini app with a personal Google account: Google’s Gemini Apps Privacy Hub says a subset of chats are reviewed by human reviewers, including trained service providers. It asks users: “Please don’t enter confidential information that you wouldn’t want a reviewer to see.” Turning off Keep Activity stops future chats from being reviewed. Temporary chats and chats with Keep Activity off are kept with your account for 72 hours; otherwise activity is auto-deleted after 18 months by default.
• Gemini in Google Workspace (work accounts): Google’s Workspace privacy hub says Workspace does not use customer data for training models without the customer’s permission, content is not human reviewed outside your domain without permission, and interactions stay within your organization.

Side by side

“Not used for training” is not the same as “not stored”. Every provider keeps data for some period to run the service, and each has its own retention rules. If retention matters for your work, read the provider’s retention page for your plan.

The plan is only half the answer

A business plan removes training by default, but the data is still leaving your company. Before pasting, ask:

• Does a contract forbid it? Client agreements and NDAs often restrict sharing information with third parties.
• Is it personal data? Data protection law may require a lawful basis and a processing agreement with the provider. Check whether your plan’s terms include one before relying on it.
• Would a leak matter? Mistakes happen: wrong account, a shared chat link, a screenshot.
• Who controls the account? On a personal account, the employee controls the settings and the chat history, and can keep it after leaving. On a business workspace, the company does. That alone is a good reason to keep work data in work accounts.

A traffic-light rule for staff

Most tasks work as well with amber or red details removed. A complaint reply does not need the customer’s address, and a formula needs only column headers, as our spreadsheet formulas guide shows. For meeting transcripts, see how to summarise meeting notes.

Settings checklist

1. Find out which account you are using: personal or a workspace managed by your employer.
2. On a personal ChatGPT account, decide on Improve the model for everyone in Settings → Data Controls.
3. On a personal Claude account, check the model improvement setting in privacy settings, and use Incognito chats for one-off sensitive drafts.
4. On a personal Gemini account, check Keep Activity, or use a temporary chat.
5. For a team, prefer a business plan or the API, and write down which tools are approved. Our AI acceptable use policy template has a ready-made section for this.

What a business plan costs

If the safest option is moving a team from personal accounts to a business plan or the API, compare the costs first. ChatGPT Plus vs Claude Pro vs Google AI Pro compares the individual plans and works through when the pay-as-you-go API is cheaper.
