Does ChatGPT Share Your Data? Key Facts for UK Businesses
Many business owners in the UK consider whether ChatGPT actually shares their data and under what circumstances. OpenAI (the provider of ChatGPT) collects prompts, other user inputs, and account details. For ChatGPT Free and Plus, your prompts may be used to further train AI models unless you proactively opt out. ChatGPT Enterprise offers enhanced data controls: it does not use business prompts for training and gives teams more visibility and control.

How Does ChatGPT Process, Store, and Delete Your Data Under UK GDPR?
What Data Does ChatGPT Collect From UK Users?
ChatGPT collects every prompt typed in, user account details like email addresses, device data, and meta-data such as access time and session frequency. Payment information is taken if you subscribe to paid versions. All this data is stored by OpenAI, at least temporarily, depending on your settings and account type.
How Long Does ChatGPT Retain Data?
OpenAI states that, under ChatGPT Free and Plus, most user prompts and related content are retained for up to 30 days—but may be kept longer if legally required. Simply deleting a chat from your account does not mean it’s wiped from OpenAI servers instantly. ChatGPT Enterprise users get better data deletion guarantees and additional admin controls for erasure and export.
What Are the Main UK GDPR Risks When Using ChatGPT for Business?
Which GDPR Principles Are Most Relevant When Using ChatGPT?
For UK businesses, several GDPR principles are especially important:
- Lawfulness, fairness, transparency: Tell people in plain English why and how their data is processed.
- Purpose limitation: Only process data for clear, legitimate business purposes.
- Data minimisation: Only input the minimum information necessary.
- Integrity and confidentiality: Secure all business and personal data.
- Accountability: You must evidence your compliance at all times.
Ignoring these can trigger an ICO investigation or fines.
Can Businesses Be Fined If Staff Share Confidential Data in ChatGPT?
Yes. If confidential client, employee, or business information is exposed, your business is accountable under UK GDPR, regardless of whether risk occurs through error or intent.
ChatGPT Free, Plus and Enterprise: Data Privacy & GDPR Compliance Comparison
Does ChatGPT Use Prompts For AI Training?
By default, ChatGPT Free and Plus prompts may be reviewed by OpenAI and used to improve its models unless you actively change your account’s data control settings. This means anything you type into ChatGPT may help refine future versions of the AI, increasing the risk that sensitive or unique data could be surfaced in outputs.
ChatGPT Enterprise makes a contractual promise that business prompts won’t be used for model training. Enterprise users also gain admin dashboards, audit trails, and improved privacy features.
Data Controllers vs Data Processors: UK GDPR Roles Explained
Data Controller vs Data Processor—What’s the Difference?
A data controller determines why and how personal data is processed. Nearly every UK business is a controller for its own data. A data processor (like OpenAI, when you use ChatGPT) processes data strictly according to the controller’s instructions.
Controllers are legally responsible for GDPR compliance, must carry out DPIAs, and are held liable for any breaches involving their data. Processors must only use data as instructed and protect it accordingly.
What Does This Mean for ChatGPT Users?
If your team enters client or staff data into ChatGPT, your business is the controller and carries legal responsibility for that data. OpenAI acts as the processor by running the platform under your direction. You must ensure you have a suitable contract in place, proper privacy notice wording, and a completed DPIA to remain compliant.
How to Use ChatGPT Legally: 7-Step UK GDPR Compliance Checklist
What Must You Do Before Introducing ChatGPT at Work?
- Assess your use case: Check if your AI use involves personal data, confidential information, or business secrets.
- Complete a DPIA: Identify and reduce potential privacy risks through a documented impact assessment.
- Update privacy notices: Clearly state your use of ChatGPT and how it handles personal data.
- Review vendor contracts: Ensure OpenAI’s processors duties are clarified in your agreements.
- Train staff: Teach all employees the dos and don’ts of AI input—what’s permitted, what’s not.
- Set up opt-outs: For Free or Plus, proactively set account preferences to stop prompts being used for model training.
- Monitor and review: Regularly audit chat logs and account settings for non-compliance or unintentional sharing.
What Should a DPIA for ChatGPT Cover?
A DPIA (Data Protection Impact Assessment) for ChatGPT must include:
- An explanation of ChatGPT’s intended business use
- The types and scope of data being processed
- Identified privacy and security risks (such as accidental disclosure or data retention)
- Proposed mitigations, including staff guidance and technical settings
- Involvement from stakeholders like team leads or your DPO
- A schedule for regular reviews
Drafting a Robust AI Usage Policy for Your Business
A clear AI usage policy defines what employees can and cannot input, outlines how outputs should be checked, and assigns roles for policy enforcement. Key elements of a legally valid AI policy include:
- Banning the entry of sensitive or personal data unless this is permitted and covered by contract and DPIA.
- Mandating employee training and regular policy reviews.
- Specifying deletion, audit, and retention processes for any AI-generated or processed data.

Common Data Mistakes with ChatGPT & How to Avoid Them
Most Common Data Disclosure Errors
- Entering client information (names, addresses, emails) into ChatGPT for summaries or drafts.
- Assuming that deleting a ChatGPT conversation instantly removes it from OpenAI’s servers.
- Not updating client privacy notices to reflect ChatGPT or other AI tool use.
- Allowing staff to use unmonitored ChatGPT Free or Plus accounts for business data without proper opt-outs.
How Can You Prevent Accidental GDPR Violations?
- Always anonymise or redact personal data before inputting it into any third-party AI tool.
- Limit staff access to AI tools and require approval for processing sensitive data.
- Carry out regular audits on chat logs and data settings.
- Ensure DPIAs and privacy policies are actively maintained and visible to your whole team.
Understanding ChatGPT’s 30-Day Data Retention Policy
OpenAI retains prompts and files for up to 30 days under standard Free and Plus accounts. Some data may be stored longer if required by law. This means even if you delete a chat or shared file locally, the data may still be accessible by OpenAI (and by extension legally available to data subjects or regulators) for up to 30 days.

Frequently Asked Questions
Is ChatGPT GDPR-compliant for business use in the UK?
ChatGPT can form part of a compliant workflow if you run a DPIA, control what staff enter, update privacy notices, and maintain clear usage policies.
Can ChatGPT use my company’s data to train its AI?
Free and Plus users may have their prompts used for model training unless they opt out in settings. Enterprise accounts are excluded from AI training by default.
How do I stop ChatGPT from using my business prompts?
For Free/Plus, go to your account’s Data Controls and opt out of training prompts. Enterprise accounts do this automatically.
What happens if my staff enter sensitive information into ChatGPT?
Your business, as data controller, could breach UK GDPR—facing possible ICO investigations or fines, and must notify impacted individuals where there’s a risk of harm.
Do I need to tell my clients that we use ChatGPT in our work?
Yes. Transparency is a legal duty. Update your privacy policy, itemise AI tool use, and obtain client consent for any personal data entered into ChatGPT.
How can I create a GDPR-compliant AI policy for my startup?
Use our AI policy builder to generate a custom, UK-specific template, including rules for data entry, output checks, and regular compliance reviews.
What should my Data Protection Impact Assessment for ChatGPT include?
It must explain your use case, identify risks, document controls, include input from staff or your DPO, and plan reviews or updates.
