Is It Safe to Put Customer or Employee Data Into ChatGPT?
A Canadian business guide to using ChatGPT with personal information, including legal authority, approved plans, data minimization, controls, and review.
Do not put customer or employee data into ChatGPT until your business has confirmed that the use is lawful, necessary, covered by an approved business account, and controlled by clear internal rules.
A vendor's security and training commitments matter, but they do not remove the organization's own privacy obligations. The Office of the Privacy Commissioner of Canada states that organizations developing, providing, or using generative AI must comply with applicable privacy laws and remain accountable for their decisions.[1]
This article provides general operational guidance, not legal advice. Privacy obligations vary by jurisdiction, sector, information type, purpose, and the relationship between the organization and the individual.
What OpenAI says about business data
OpenAI states that it does not train its models on an organization's inputs or outputs by default when the organization uses ChatGPT Business, ChatGPT Enterprise, ChatGPT Edu, ChatGPT for Healthcare, ChatGPT for Teachers, or the OpenAI API Platform.[2]
OpenAI also states that business data is encrypted at rest with AES-256 and in transit using TLS 1.2 or higher. Its business offerings include administrative and security controls that vary by product and plan.[2]
Those commitments answer part of the vendor-risk question. They do not answer all of the business's legal and operational questions, including:
- whether the organization has legal authority for the specific use;
- whether the individual received required notice;
- whether the information is necessary for the task;
- whether the correct ChatGPT plan and workspace are being used;
- who can access the inputs, outputs, and history;
- how long information is retained;
- where human review is required;
- what happens if the output is inaccurate, biased, or disclosed improperly.
Canadian privacy rules still apply
Canada's privacy commissioners published joint principles for responsible, trustworthy, and privacy-protective generative AI. Their guidance says organizations should establish and document legal authority for collecting, using, and disclosing personal information; limit collection and use to what is necessary; apply safeguards; be transparent; and remain accountable.[1]
The guidance also makes two points that are easy to miss:
- Information being publicly accessible does not automatically permit indiscriminate collection or use.
- An AI-generated inference about an identifiable person can itself be personal information and require legal authority.[1]
The business must therefore evaluate both the information entered into the system and personal information that may be inferred or produced.
A practical decision process before anyone pastes data
1. Identify the exact purpose
Write a narrow use statement. For example: "Use approved records to prepare a draft summary for review by an authorized employee."
Avoid broad purposes such as "use AI to analyze our customers." A narrower purpose makes necessity, access, retention, and review easier to assess.
2. Identify the information involved
List each data element and classify it under the organization's own policy. Common categories include:
- public information;
- internal business information;
- confidential commercial information;
- personal information;
- sensitive personal information;
- regulated or contract-restricted information.
This classification is a practical management method. The legal definition and treatment of each data element depends on the applicable law and context.
3. Confirm legal authority and contractual permission
Check the privacy law, employment context, customer commitments, confidentiality clauses, data-processing agreements, professional obligations, and sector rules that apply. If the answer is unclear, pause the use case and obtain appropriate privacy or legal advice.
4. Use an approved business workspace
Do not assume that every ChatGPT account has the same data terms, controls, administration, or retention options. OpenAI's published no-training-by-default commitment cited above applies to named business, education, healthcare, and API offerings.[2]
The organization should approve the specific product, plan, workspace, settings, connectors, and user accounts before personal or confidential information is used.
5. Minimize and de-identify where possible
The privacy commissioners recommend limiting collection and use to what is necessary for the stated purpose.[1] Remove direct identifiers and unnecessary details whenever the task can still be completed without them.
De-identification is not just deleting a name. Combinations of details may still identify a person. The appropriate method depends on the data and re-identification risk.
6. Control access and retention
Define:
- who may submit information;
- which roles may see outputs and histories;
- how accounts are authenticated;
- how connected sources are permissioned;
- how long data and outputs are kept;
- how access is revoked when roles change;
- how incidents are reported.
7. Review the output before use
NIST identifies confabulation as a risk in which generative AI confidently presents false or erroneous content.[3] Personal-data workflows can also produce unsupported inferences or reproduce bias.
A qualified person should review factual accuracy, source support, relevance, fairness, and appropriateness before the output affects an individual or leaves the organization.
A simple employee rule
Until a use case is approved, employees should not enter customer, employee, financial, health, credential, legal, confidential, or contract-restricted information into an AI service.
An approval should identify:
- the exact AI product and workspace;
- the permitted purpose;
- permitted and prohibited data;
- required de-identification;
- the reviewer;
- retention and deletion rules;
- the person to contact when uncertain.
Frequently asked questions
Does "not used for training" mean the data is automatically safe to upload?
No. It describes one part of the vendor's data practice. The organization must still assess legal authority, necessity, security, access, retention, accuracy, contracts, and the specific use case.
Is it safe if we remove the person's name?
Not always. Other details may identify the person directly or in combination. The organization should assess re-identification risk and remove information that is not necessary.
Can staff use a personal ChatGPT account for business work?
A business should define approved products and accounts rather than leaving that decision to individual employees. Product terms and controls differ, and the organization remains accountable for its handling of personal information.
Who is responsible if the AI produces a harmful or incorrect decision?
The privacy commissioners state that accountability for decisions rests with the organization, not the automated system supporting the decision.[1]
