Information That Can Never be Shared with ChatGPT and AI

Artificial intelligence (AI) chatbots like ChatGPT have revolutionised how we seek information, draft emails, and even brainstorm ideas. However, as these tools grow more advanced, so do the risks of oversharing. Unlike human confidants, AI does not forget-every input may be processed, stored, or potentially exposed.

To safeguard your privacy, never share these five categories of information with ChatGPT or similar AI tools:

1. Personally Identifiable Information (PII)

Full name, home address, or phone number
National ID (NID) number, passport, or driving licence details Birthplace, family members’ names, or biometric data

 AI platforms may log conversations to improve performance. While companies like OpenAI claim data anonymisation, breaches or misuse could expose sensitive details to hackers or third parties.

2. Financial Secrets

Credit/debit card numbers and CVV codes
Bank account numbers and PINs
Bank account statements
Mobile phone numbers linked to Mobile Financial Services (MFS) Cryptocurrency wallet keys and investment amounts

Why it’s risky: Cybercriminals actively target financial data. Even if ChatGPT doesn’t store information permanently, a screenshot or accidental leak could lead to fraud or identity theft.

3. Passwords and Login Credentials

Email, social media, or banking passwords
Two-factor authentication (2FA) codes
Security question answers (e.g., “Mother’s maiden name”)

Why it’s risky: AI chats are not encrypted like password managers. If your chat history is compromised, attackers could take control of your accounts.

4. Confidential Work Data

Unreleased product designs or patents
Internal company strategies or financial reports
Proprietary code or client contracts

Why it’s risky: Many employers explicitly ban AI tools for confidential work. Leaks could violate non-disclosure agreements (NDAs) or intellectual property laws, risking legal consequences or job dismissal.

5. Private or Illegal Disclosures

Medical records or mental health struggles
Relationship conflicts or family disputes
Admissions of illegal activity (even jokingly)

Why it’s risky: AI responses aren’t legally privileged. In extreme cases, authorities could subpoena chat logs as evidence.

Bonus tip: How to use ChatGPT safely

While AI chatbots offer incredible convenience, protecting your privacy is crucial. Follow these simple rules to stay secure:

Use generic examples- replace real names, dates, or figures with fictional placeholders.
Never paste sensitive documents- avoid sharing contracts, NID scans, or confidential files.
Treat chats as public- even deleted conversations may persist in backups or logs.

The Bottom Line
ChatGPT is a tool, not a vault. Treat it like a crowded room: if you wouldn’t say it aloud there, don’t type it here.
