What Can You Type Into AI? Will Your Information Leak?
This is one of the questions people age 40+ ask most often before starting with AI, and it is a very good question because it means you know how to be careful.
You can use AI safely if you know a few simple rules.
The easiest way to think about it is this: imagine you are talking to a stranger with a very good memory. General topics are fine to discuss, but if there is something you would not want anyone to know, do not tell it yet.
The information you type into AI may be stored to improve the system. Always assume that what you type may not be 100 percent confidential.
3 Things You Should Not Type In
Remember these 3 categories, and you can use AI with more peace of mind.
Information Used to Verify Your Identity
ID card numbers, bank account numbers, credit card numbers, or OTP codes should never be typed into AI under any circumstances, because they are keys to your identity and your money.
If you want AI to help with documents related to these things, replace the real numbers with words like “ID number,” or use made-up numbers instead.
Passwords of Any Kind
Email passwords, banking app passwords, workplace Wi-Fi passwords: there is no reason to tell AI these. AI can help you without knowing any of these passwords.
Other People’s Secrets and Company Secrets
Customer information, confidential contracts, private matters involving people around you, or internal workplace information should be kept private, because it is not your information alone to decide to reveal.
3 Things You Can Type with Confidence
After reading this far, do not get so worried that you are afraid to use AI. Most everyday tasks can be typed safely.
General Knowledge Questions
Ask about basic health information, history, cooking methods, or things you want to understand. You can type freely because this is public knowledge already.
Draft Work That Has No Confidential Information
Ask it to draft emails, write greeting messages, summarize articles, or brainstorm ideas. As long as sensitive personal information is not mixed in, this is fine.
Fictional Information Instead of Real Information
If you want AI to help calculate or plan something that requires numbers, try using fictional but realistic numbers instead of your real ones. You get the same kind of result without revealing real information.
Simple Settings to Increase Safety
Most AI tools have privacy settings you can adjust yourself.
In ChatGPT, you can go into settings and turn off the option that allows your conversations to be used for system training. Once it is turned off, what you type will not be used to improve the model.
Another method is to delete your conversation history from time to time, like clearing your browser history, so old information does not remain in the system.
Stay on the Safe Side
If you are not sure whether a piece of information is okay to type, use one simple rule: if it is something you would not feel comfortable telling a stranger, do not type it into AI.
This caution lets you use AI with peace of mind, which matters more than using it a lot while still worrying about your data.
Update box: What Data Protection Options Are Available Right Now (June 2026)?
This section contains information that changes according to the AI’s capabilities and will be updated regularly. The core concepts above will always apply.
Major AI apps now have options to stop your conversations from being used for further training, and they offer business plans with stricter data protection than general consumer versions. Try opening the privacy settings in the app.
Even with these options, the original principle is still best: do not type personally identifiable information or secrets in the first place.
