Can we reuse customer or employee data in an AI tool? Only after assessing what the data was collected for, what the AI will do with it, what affected people could reasonably expect, and what risks and safeguards apply. Having data on hand does not automatically make a new AI use appropriate.
The answer depends on the jurisdiction and the facts. UK guidance emphasizes compatibility with the original purpose; Australian guidance highlights reasonable expectations and the relationship to the primary purpose. Neither is a universal legal test. The practical business decision is whether to proceed with controls, narrow the use, seek consent or offer an opt-out where appropriate, or not reuse the information.
Why an existing dataset can create a new privacy risk
Privacy risk can arise when personal information is put to a purpose beyond the one specified when it was collected. The National Institute of Standards and Technology (NIST) says such processing can create privacy risks, and that measures should be commensurate with those risks. In an AI context, the proposed use might be to develop a model or to deploy one in a business process; those are distinct purposes to identify and assess.
The issue is not limited to whether information was lawfully collected in the first place. A new use may change who or what is affected, how the information is processed, and what could happen if it is exposed or used unexpectedly. Public accessibility does not settle the question either: the OECD’s 2024 report notes that publicly accessible sources can contain personal data, and that accessibility alone does not make collection and AI-training use unrestricted.

What to assess before reusing information in AI
1. Describe the proposed use
Write down what information is involved, why it was originally collected, and the specific new AI-related purpose. State whether the tool will be used to develop a model or deploy one. Identify who may be affected and what the system is expected to do with the information. A description such as “use customer data for AI” is too broad to support a meaningful decision.
2. Check purpose fit and people’s expectations
Compare the proposed use with the purpose explained at collection, then consider whether affected people could reasonably expect the new use. Apply the relevant jurisdiction’s rules rather than treating purpose compatibility and reasonable expectations as one global test.
- United Kingdom: The Information Commissioner’s Office (ICO) says a new purpose must be compatible with the original purpose under its UK GDPR purpose-limitation guidance. The guidance page was updated on March 23, 2026, including changes reflecting the Data (Use and Access) Act. Record the purposes as part of the organization’s documentation obligations.
- Australia: The Office of the Australian Information Commissioner (OAIC) says secondary AI use should be assessed in light of people’s reasonable expectations and its relationship to the primary purpose. If an organization cannot clearly establish those factors, OAIC says it should seek consent and/or offer a meaningful, informed opt-out to reduce regulatory risk.
These are jurisdiction-specific sources, not a complete legal checklist for every location. The OECD’s principles-level discussion can inform an organization’s thinking, but it does not replace analysis under applicable law.

Identify plausible consequences for people and for the organization if the information is exposed, processed in an unexpected way, or used to produce an outcome that affects someone. Consider the sensitivity of the information and how it will be handled by the AI service. Then identify safeguards that address the risks of this particular use. NIST’s guidance supports matching risk-management measures to the risks; it does not prescribe a universal set of controls for every AI project.
4. Document the decision and choose a response
Keep a record of the proposed purpose, the assessment of purpose fit and expectations, the risks considered, the safeguards selected, and the reason for proceeding or declining. The documentation should make the business judgment understandable to people responsible for privacy, security, and the AI system—not merely record that approval occurred.
Depending on the facts and governing law, a business can proceed with suitable controls, narrow the use, seek consent or provide an opt-out where appropriate, or avoid using the information for that purpose. In the Australian scenario described by OAIC, consent and/or a meaningful, informed opt-out is the stated risk-reduction response when reasonable expectations or the relationship to the primary purpose cannot be clearly established.

How the decision changes for public AI chatbots
Publicly available AI chatbots warrant a clear data-entry rule. OAIC recommends as best practice that organizations do not enter personal information—particularly sensitive information—into publicly available AI chatbots because of the significant and complex privacy risks. This is an Australian regulator’s best-practice recommendation, not a universal legal rule.

For a business, the practical response is to tell staff what information may not be entered into public tools and to direct them to an approved alternative or a process for getting the use assessed. A tool’s public availability or convenience does not itself establish that it is suitable for personal information.
Best Value
Use frameworks to organize governance, not to replace law
NIST’s AI Risk Management Framework (AI RMF) can help organizations structure risk work across AI design, development, use, and evaluation. NIST describes it as voluntary; it is not a legal safe harbor. NIST also states that its Privacy Framework does not have the force or effect of law. These resources can support internal governance, but the applicable legal obligations still depend on the jurisdiction and the specific processing.
NIST reports that the AI RMF is being revised, so organizations using it should check the current framework materials when setting or updating internal processes.
A practical choice: reuse, restrict, or do not reuse
Compare the proposed AI use with a restricted-use or no-reuse alternative. The point is not to assume that AI use is always inappropriate, but to make the trade-off explicit and document why the selected option is suitable.

Pick the symptom - the matching free tool is one click away.
- Purpose fit: Is the proposed use compatible with the original purpose under the applicable law? Where relevant, how does it relate to the primary purpose?
- Expectations: Was the use explained at collection, and can the organization establish that affected people could reasonably expect this secondary use?
- Sensitivity and exposure: Does the proposal involve personal or sensitive information, particularly in a publicly available tool?
- Risk management: Are safeguards proportionate to the risks, and can a voluntary framework such as NIST AI RMF help structure the work without being mistaken for law?
- Accountability: Can the organization explain the purpose, assessment, safeguards, and reason for its decision in its records?
If the purpose fit or expectations are unclear, or the risks cannot be managed acceptably, narrowing the use or declining it may be a better business decision than reusing the data as proposed.
