| 5 Things You Should Never Tell ChatGPT: Protect Your Personal Information |
Introduction
As AI chatbots such as ChatGPT, Gemini, Copilot, and Claude become part of everyday life, users are increasingly turning to them for writing, research, health questions, work tasks, and personal advice. But convenience can come with AI privacy risks, especially when users share information that could identify them or expose confidential details.
- So, what should you avoid telling ChatGPT? The safest approach is to avoid sharing personal, medical, financial, confidential business, and highly intimate information unless you fully understand the service's privacy settings and policies.
Key Points
Avoid sharing personal identification information.
Do not upload sensitive medical records containing identifying details.
Keep banking and financial information private.
Never paste confidential company information or protected code.
Think carefully before sharing highly intimate personal details.
Review the AI privacy settings of the chatbot you use.
Remove names, addresses, account numbers, and other identifiers from documents before uploading them.
What Should You Never Tell ChatGPT?
There are five major categories of information that deserve extra caution when using an AI chatbot.
1. Personal Identification Information
What Counts as Personal Information?
Personal information includes details that can directly identify you, such as:
Full name
Home address
Phone number
Passport number
Driver's license number
Personal email address
Account numbers
Sharing several of these details together can create unnecessary privacy and identity theft risks.
Why Is This Information Sensitive?
Personal identifiers can potentially be combined with information from other sources to create a more complete profile of an individual.
For this reason, remove unnecessary identifiers before uploading a résumé, application, legal document, or other personal file to an AI chatbot.
Expert Quote: “If you share sensitive information in a dialogue with ChatGPT, Gemini, or other frontier models, it may be collected and used for training,” Stanford privacy researcher Jennifer King warned. (Stanford HAI)
2. Highly Intimate Personal Details
Why Do People Overshare With AI?
Conversational interfaces can feel more personal than traditional search engines. A user may therefore reveal thoughts, relationship problems, behavioral details, or other sensitive information without considering how that information is handled.
Stanford researchers have highlighted the growing privacy concerns associated with people disclosing intimate information through chatbot interfaces. (Stanford HAI)
What Should You Avoid Sharing?
Be cautious about providing:
Highly sensitive relationship details.
Private family disputes.
Intimate behavioral information.
Information that could embarrass or identify you.
Details that could be used to impersonate or manipulate you.
3. Medical Information
Can You Ask AI About Health?
Yes. AI can help explain medical terminology, prepare questions for a doctor, or organize general health information. However, users should avoid unnecessarily entering identifiable medical records.
Sensitive information may include:
Medical history
Patient identification numbers
Hospital records
Prescription details linked to your identity
Laboratory reports containing personal information
Insurance information
How Can You Protect Medical Privacy?
If you need help understanding a document, consider removing your name, address, medical record number, date of birth, and other identifying details first.
Important: AI-generated health information should not replace professional medical advice, diagnosis, or treatment.
4. Confidential Work Information
What Business Data Should Stay Private?
Employees should be particularly careful when using public or consumer-facing AI tools for workplace tasks.
Avoid entering:
Confidential company reports
Customer information
Trade secrets
Non-public financial data
Passwords and access credentials
Confidential contracts
Protected source code
Information covered by a non-disclosure agreement
Why Does This Matter?
Uploading confidential material could conflict with company policies, contracts, intellectual-property protections, or regulatory requirements.
Stanford research has also examined how uploaded documents and other files may fall within the data practices of AI services, depending on the provider and its policies. (Stanford HAI)
Expert Quote: Stanford researchers recommend minimizing the amount of sensitive personal data supplied to AI systems and making data-handling practices clearer to users. (Stanford HAI)
5. Financial Information
Which Financial Details Should You Protect?
Never casually paste sensitive financial information into an AI chatbot, including:
Bank account numbers
Credit card numbers
Online banking credentials
Investment account details
Tax documents
Salary statements
Financial identification numbers
Why Is Financial Data Risky?
Financial information can be valuable to criminals attempting fraud, impersonation, phishing, or social-engineering attacks.
Even when you need help understanding a financial document, it is better to remove account numbers, addresses, names, and other unnecessary identifiers.
AI Privacy: What Should You Check Before Sharing?
Before entering sensitive information, ask yourself three questions:
Does the chatbot really need this information?
Can I remove identifying details first?
Have I checked the service's current privacy and data-control settings?
These simple steps can significantly reduce unnecessary exposure.
Can ChatGPT Conversations Be Used for Training?
The answer depends on the product, account type, settings, and applicable policies.
A Stanford HAI analysis of six major U.S. AI developers found significant differences in how services handled chatbot inputs, training, retention, and user choices. (Stanford HAI)
OpenAI, for example, currently provides Data Controls that allow users to turn off the setting that lets conversations help improve its models. (OpenAI Help Center)
Use Temporary Chats for Sensitive Questions
OpenAI says Temporary Chats are not used to train its models and are automatically deleted, while also not being added to ChatGPT memory. (OpenAI)
Users should still avoid treating any online service as a place to store highly sensitive information unnecessarily.
Remove Personal Details From Files
Before uploading a document, consider deleting:
Names
Addresses
Phone numbers
Identification numbers
Account numbers
Signatures
Passwords
Confidential references
This practice is often called data minimization.
What About Passwords?
Passwords and authentication codes should never be entered into an AI chatbot.
The same rule applies to:
One-time passwords
Recovery codes
API keys
Private encryption keys
Security tokens
These credentials should remain in appropriate password managers or secure organizational systems.
Does AI Privacy Mean You Should Stop Using Chatbots?
No. AI privacy is primarily about using these tools thoughtfully.
Chatbots can be extremely useful for:
Writing and editing
Learning
Brainstorming
Research assistance
Summarizing non-sensitive information
Preparing questions for professionals
The key principle is simple: share the minimum information necessary to complete the task.
How to Use AI More Safely
Follow these practical steps:
Read the privacy settings.
Check whether conversations can be used for model improvement.
Use temporary or equivalent privacy-focused modes when appropriate.
Remove identifying information from documents.
Never share passwords or authentication codes.
Avoid confidential workplace material.
Review uploaded files before sending them.
Delete conversations you no longer need when appropriate.
Did You Know?
Did You Know? AI privacy policies can differ substantially between providers. Stanford researchers examined privacy documentation from six major U.S. AI developers and found differences in training practices, retention periods, and opt-out mechanisms. (Stanford HAI)
Expert Opinion
Why Is Data Minimization Important?
Privacy researchers increasingly emphasize data minimization: provide an AI system with only the information it needs to perform the requested task.
For example, if you want an AI tool to improve your résumé, it may not need your home address, telephone number, passport details, or other identifiers.
OpenAI also describes privacy safeguards and user controls designed to give users choices over how their data is handled. (OpenAI)

Some AI services offer memory features or conversation history. The exact behavior depends on the service, account, and settings. OpenAI says users can manage memory and data controls through available settings. (OpenAI)
Can I use ChatGPT for confidential work?
Only when your organization's policies and the specific AI service permit it. Consumer AI tools should not automatically be treated as approved repositories for trade secrets, customer information, or confidential company material.
What is the safest way to use AI chatbots?
The safest general approach is data minimization: provide only what the chatbot needs, remove unnecessary identifiers, and check the provider's current privacy controls before sharing sensitive information.
Conclusion
ChatGPT and other AI chatbots can make everyday tasks faster and easier, but convenience should not mean unlimited disclosure. Personal identifiers, intimate details, medical records, confidential business information, and financial data deserve particular caution.
The best rule is straightforward: if you would not want the information unnecessarily stored, reviewed, or exposed, think carefully before entering it into an AI chatbot.
By combining AI privacy settings, data minimization, careful file preparation, and basic cybersecurity habits, users can benefit from artificial intelligence while reducing unnecessary privacy risks.
