AI and Your Privacy: What AI Tools Learn About You

Your prompt is data, not a private conversation

When you chat with an AI tool, your words travel to a company's servers, may be stored in your chat history, and — depending on the tool and its settings — may be reviewed by staff or used to improve future models. That does not make AI tools dangerous, but it does mean you should treat them like a public noticeboard with a good memory, not like a diary. The rule is simple: if you would not want it quoted back to you, do not paste it into an AI tool.

What AI tools typically collect

• Your prompts and uploads — the text, images, files and code you send
• Account and device details — your email, device type, location region and usage patterns
• Conversation history — saved chats that the tool can remember across sessions, unless you delete them
• Feedback signals — thumbs up or down, corrections and regenerations, which also teach the system

Some tools also offer “memory” features that remember facts about you across chats. Useful, but remember: every remembered fact is a fact stored somewhere else, not only in your head.

The never-paste list

• Passwords, PINs, one-time codes and bank or card details — never, in any tool
• Your full address, ID numbers, passport or student ID details
• Private photos, especially of children or other people, and voice recordings of others
• Other people's personal data — a classmate's assignment, a colleague's email, a client's document
• Unpublished work you must submit as your own, exam papers, or confidential workplace documents

When you need help with code or writing, paste a small, invented example that shows the same problem instead of your real file. You get the same help with none of the exposure.

Check the settings — a 10-minute privacy audit

• History: find the chat-history setting and decide whether you want chats saved; delete old chats you no longer need
• Training: look for a setting about using your data for training or improvement, and turn it off if you prefer your prompts not to be used that way
• Memory: review what the tool remembers about you and delete anything you do not want stored
• Sharing: check whether shared links make a chat public — never share a link to a chat containing anything personal
• Apps and logins: remove AI apps and browser extensions you no longer use, and keep the ones you keep updated

AI at school, university and work

Follow your institution's rules first: some universities and employers restrict which AI tools you may use and what you may upload. When in doubt, ask before pasting coursework, research data or work documents. Using AI to learn — explanations, practice questions, feedback on your own draft — is very different from uploading someone else's private material or submitting AI output as your own work.

Practice task (20 minutes)

Run the privacy audit above on one AI tool you actually use: check its history, training and memory settings, delete two old chats, and write down in your own words what the tool stores. Then rewrite one past prompt you sent into a safe version — same question, invented example, no personal details — and compare: did the safe version still get you the help you needed?

Common mistakes to avoid

• Assuming a chat window is private because it feels like a conversation
• Pasting a whole document when a short example would do
• Sharing a chat link without checking what is inside it
• Uploading photos or documents belonging to other people without their permission
