AI tools have become part of everyday life. People use them to write emails, understand documents, prepare presentations, improve resumes, study difficult topics, create business plans, and solve daily problems.
The convenience can make an AI chat feel like a private conversation. You type a question, receive an instant response, and continue talking as if you were messaging a helpful assistant.
However, an AI chatbot is still an online service. The information you enter may be processed, stored, connected with other services, or handled according to the provider’s privacy policy and your account settings.
Different AI platforms follow different data practices. Some provide temporary conversations, training controls, memory settings, and deletion options. Others may use selected conversations to improve their products or allow trained reviewers to examine some data. Google’s Gemini privacy notice, for example, specifically advises users not to enter confidential information they would not want a reviewer to see.
This does not mean you should stop using AI. It means you should learn what not to share with AI tools and how to ask for help without exposing sensitive information.
Here are 12 types of information you should keep private.
1. Passwords, PINs and Security Answers
Never paste a password into an AI chatbot.
This includes passwords for:
- Email accounts
- Social media profiles
- Banking applications
- WordPress websites
- Cloud storage
- Work accounts
- Payment services
- Wi-Fi networks
You should also keep PINs, account recovery codes, backup codes, security-question answers and device unlock patterns private.
You may sometimes want AI to check whether a password is strong. Instead of sharing your real password, create a fictional example with a similar structure.
For example, do not type:
My real password is Rumpa@Bank2026. Is it secure?
Ask:
Is a 16-character password containing random letters, numbers and symbols generally stronger than a short password based on a name?
Use a trusted password manager to generate and store unique passwords. The FTC also recommends strong passwords and two-factor authentication to protect online accounts.
2. One-Time Passwords and Verification Codes
A one-time password, commonly called an OTP, is designed to confirm that the person logging in or approving a transaction is really you.
Never share:
- Banking OTPs
- Email verification codes
- Login approval codes
- Password-reset codes
- SIM verification codes
- Two-factor authentication codes
A legitimate AI assistant does not need your OTP to explain how a login process works.
Scammers may create fake chatbots, websites or support messages that look trustworthy. If anyone or any tool asks for a verification code, stop immediately and use the official app or website instead.
A code that expires in a few minutes can still give someone enough time to access an account or approve a transaction.
3. Bank Account and Payment Details
Do not paste complete financial information into a general-purpose AI tool.
Keep the following private:
- Bank account numbers
- Debit or credit card numbers
- CVV codes
- UPI PINs
- Net-banking credentials
- Payment screenshots
- Loan account details
- Complete bank statements
- Cryptocurrency recovery phrases
- Wallet private keys
You can still use AI to create a budget, understand financial terms or organize expenses. The safer method is to replace real information with general categories.
Instead of uploading a statement containing your name, account number and transactions, write:
My monthly income is approximately ₹40,000. My main expenses are rent, food, travel and subscriptions. Help me create a basic budget.
This gives the AI enough information to help without exposing your financial identity.
4. Government Identification Documents
Identity documents contain information that can be misused for impersonation, account creation or fraud.
Avoid uploading unedited copies of:
- Aadhaar cards
- PAN cards
- Passports
- Driving licences
- Voter identification cards
- Birth certificates
- Social-security documents
- Residence permits
- Employee identity cards
These documents may contain your full name, date of birth, photograph, signature, identification number and address in one place.
The FTC advises people to protect documents containing personal and financial information and to question whether an organization genuinely needs a sensitive identifier before providing it.
When you need help understanding a form, remove or cover all identifying details before uploading it. You can also type only the section or question you do not understand.
5. Confidential Work and Client Information
AI can help summarize reports, improve proposals and draft professional messages. But you should not paste confidential workplace information into an unapproved public AI tool.
Examples include:
- Customer names and contact details
- Private contracts
- Internal emails
- Employee records
- Salary information
- Sales databases
- Unreleased financial results
- Supplier pricing
- Meeting transcripts
- Legal disputes
- Password-protected company documents
Your employer or client may have specific rules about which AI services are approved. Breaking those rules could damage trust or violate a contract, even when you had no harmful intention.
Before using AI for work, ask:
- Is this tool approved by my organization?
- Does the document contain personal or confidential data?
- Can I remove names, figures and identifying details?
- Can I describe the problem without uploading the original file?
A safe prompt might be:
Write a polite follow-up email for a customer who has not replied in seven days.
You do not need to include the customer’s name, phone number, order history or private messages.
6. Medical Records and Identifying Health Information
People often use AI to understand symptoms, medical terms, test reports or questions they want to ask a doctor.
General health education can be useful, but avoid sharing complete medical records containing identifying information.
Keep private:
- Patient names
- Hospital registration numbers
- Prescription numbers
- Insurance details
- Complete laboratory reports with personal data
- Medical identification numbers
- Detailed psychiatric records
- Reproductive or sexual-health records linked to your identity
You can remove your name, address, date of birth, QR codes, barcodes and registration numbers before asking for a general explanation.
For example:
Explain in simple language what a high cholesterol result generally means.
This is safer than uploading a full report containing your identity.
AI should not replace a qualified medical professional, particularly when symptoms are serious, urgent or highly personal.
7. Private Conversations and Other People’s Secrets
A private message does not belong only to the person who received it. It also contains the words, emotions and personal details of the person who sent it.
Before copying a WhatsApp conversation, email thread or private message into an AI tool, consider whether the other person would agree.
Avoid uploading conversations involving:
- Relationship problems
- Family disputes
- Workplace complaints
- Financial difficulties
- Health conditions
- Personal photographs
- Intimate details
- Confidential confessions
You can describe the situation without copying the exact conversation.
Instead of pasting fifty private messages, write:
A friend feels ignored because I have been busy. Help me write a sincere apology that does not sound defensive.
This protects both people while still allowing the AI to help.
8. Children’s Personal Information
Children may not understand the long-term consequences of sharing personal data online. Adults should therefore be especially careful when using AI tools for schoolwork, parenting or family activities.
Do not share a child’s:
- Full name
- Home address
- School name
- Class schedule
- Identification number
- Medical record
- Daily travel route
- Private photograph
- Phone number
- Live location
When asking AI to help with homework or learning activities, use only the academic question.
Instead of saying:
My nine-year-old daughter Priya studies at ABC School in Kolkata and has a learning difficulty. Here is her complete report.
Say:
Create a simple reading exercise for a nine-year-old learner who needs short sentences and extra repetition.
The second prompt gives useful context without identifying the child.
9. Exact Home Address and Live Location
AI tools can help plan travel, find nearby services and organize daily schedules. However, sharing your exact location is not always necessary.
Avoid combining details such as:
- Full home address
- Apartment number
- Daily departure time
- Workplace address
- Child’s school route
- Dates when your home will be empty
- Real-time travel location
- Hotel room number
Small details can become sensitive when combined.
For a restaurant recommendation, your city or neighbourhood is usually enough. For travel planning, share the destination and approximate dates without giving unnecessary booking numbers or exact accommodation details.
Ask:
Suggest quiet cafés near Salt Lake, Kolkata.
Do not provide your complete address unless a trusted service genuinely requires it.
10. Legal, Tax and Insurance Documents
Legal and financial documents often contain several categories of sensitive information at once.
These may include:
- Full names
- Signatures
- Addresses
- Account details
- Property records
- Tax numbers
- Policy numbers
- Case information
- Witness details
- Confidential legal advice
AI may help explain difficult language, but uploading an entire unedited document can create unnecessary privacy risk.
A better approach is to copy only the clause you need explained and replace all names and numbers with placeholders.
For example:
Explain this contract clause in simple language. Replace “Company A” and “Client B” with generic parties.
For important decisions, verify the explanation with a qualified lawyer, accountant, tax professional or insurance adviser.
11. Business Secrets, Source Code and Access Keys
Developers, freelancers and business owners often use AI to troubleshoot code or improve business strategies.
Do not share:
- API keys
- Database passwords
- Authentication tokens
- Private repositories
- Customer databases
- Server credentials
- Proprietary algorithms
- Unreleased product designs
- Secret pricing plans
- Private marketing strategies
An API key can sometimes provide direct access to a paid service or company system. Treat it like a password.
Before pasting code, search for:
- Usernames
- Internal URLs
- Email addresses
- Tokens
- Keys
- Database strings
- Customer details
- Hidden comments
Replace them with obvious placeholders such as:
YOUR_API_KEY
EXAMPLE_EMAIL
DATABASE_URL
CLIENT_NAME
The AI usually does not need your real credentials to identify a coding error.
12. Signatures, Biometrics and Intimate Images
Your signature, face, voice and fingerprints can be used to confirm your identity. High-quality samples may also be misused for impersonation or synthetic media.
Be careful with:
- Scanned signatures
- Voice recordings containing private details
- Clear identity photographs
- Fingerprint images
- Face-verification videos
- Intimate photographs
- Private family images
- Documents showing both your face and identification number
Before uploading an image for editing or analysis, check the background for visible addresses, badges, number plates, computer screens, private documents or children.
Crop the image when possible. Blur identifying details and remove embedded location information before sharing sensitive photographs online.
Never upload another person’s private image without permission.
Privacy Settings Help, but They Are Not Permission to Overshare
Some AI tools provide useful privacy controls.
OpenAI currently allows users to turn off the setting that lets future conversations help improve its models. It also provides Temporary Chats, which are not used for training, do not create memories and are automatically deleted. Users can also manage saved memories and connected-app access.
These controls are valuable, but they should support good privacy habits rather than replace them.
Even when training is disabled, you should still avoid entering passwords, OTPs, banking credentials or confidential documents. Privacy settings reduce certain forms of data use; they do not make every type of disclosure necessary or risk-free.
A Safer Way to Use AI
Before submitting a prompt or uploading a file, use this quick process:
Remove
Delete names, account numbers, addresses, passwords and identifying details.
Replace
Use fictional placeholders such as “Client A,” “Employee B” or “Example Company.”
Reduce
Share only the small section needed to answer your question.
Review
Check the tool’s privacy policy, data controls, memory settings and connected applications.
Reconsider
Ask whether you would be comfortable seeing the information in an email accidentally sent to the wrong person.
If the answer is no, do not paste it into a general AI chatbot.
What to Do If You Already Shared Sensitive Information
Do not panic, but act quickly.
First, delete the conversation if the platform provides that option. Then review its privacy and data-control settings.
If you shared a password, change it immediately and sign out of other active sessions. Turn on two-factor authentication.
If you shared an API key, revoke it and create a new one.
If you shared banking information, contact your bank and monitor your account.
If you exposed an identity document, watch for suspicious messages, login attempts or accounts opened in your name.
If the information belongs to an employer, customer or client, follow the organization’s security-reporting process instead of trying to hide the mistake.
Final Thoughts
AI tools are useful because they can work with the information we provide. That same ability makes privacy awareness essential.
The safest approach is not to avoid AI completely. It is to give the tool only the information it genuinely needs.
Do not share passwords, verification codes, banking information, identity documents, confidential work files, private medical records, children’s data, exact location details, legal documents, business secrets or biometric information.
Before pressing Enter, pause for a few seconds and ask:
Does the AI really need this exact information to help me?
In many cases, the answer is no. You can remove the identity, simplify the situation and still receive a useful response.
Use AI for assistance—not as a storage place for your most private information.
FAQ
Is it safe to share personal information with AI tools?
It is better to avoid unnecessary personal information. Check the platform’s privacy policy and settings, and remove names, addresses, identification numbers and confidential details before submitting a prompt.
Can I upload a document after hiding my name?
Hiding your name is a good first step, but inspect the complete document. It may still contain account numbers, QR codes, addresses, signatures, metadata or other identifying information.
Are temporary AI chats completely risk-free?
Temporary-chat features can reduce storage, memory and training use depending on the provider, but they are not a reason to share passwords, banking credentials or highly confidential information.
Can I use AI to understand a medical or legal document?
You can ask for a general explanation after removing identifying details. Important medical or legal decisions should still be confirmed with a qualified professional.
What is the safest rule for using AI?
Share the minimum information required. When possible, replace real details with fictional examples or general descriptions.
