Is It Safe to Use AI? What Not to Share
Written for parents, people getting started later in life, small business owners, and creators.
Last updated October 16, 2026
AI tools can be useful, but a chat box is not the place for secrets. Never paste passwords, card numbers, ID numbers, or private health and family details. Share only what the task truly needs.
Treat the chat like a message to a company
An AI chat can feel personal because it answers in a friendly way. It is still a service run by a company. The words and files you submit travel through that service.
Before you paste something, ask: would I be comfortable putting this in an ordinary online form? If not, remove the private parts or use a blank placeholder.
What never to paste in
A useful prompt rarely needs your most sensitive information. Replace real details with words such as [account], [child], [customer], or [medical question].
- Passwords, sign-in codes, or security answers.
- Credit card, bank account, or payment details.
- Social Security, driver's license, passport, or other ID numbers.
- Private health records or details that identify a person.
- Private family, school, employee, or customer information.
- Confidential workplace documents or private contracts.
Review privacy settings in the tool you use
Look in the tool's settings for sections named privacy, data controls, chat history, memory, or training. The names and choices can change, so read the explanation shown in the tool itself.
A setting is not a reason to share more than necessary. Keep using blanks, summaries, and made-up examples whenever the real details are not needed.
A simple example
Someone wants help understanding a medical bill. The AI tool does not need the patient's name, account number, address, or diagnosis. The person removes those details and asks only about the general wording.
Explain these general billing terms in plain English: amount billed, allowed amount, and patient responsibility. Do not give medical or legal advice. I have removed all names, account numbers, and health details.
What to look for
- Only general explanations, without private information.
- A reminder to check the real bill or contact the correct organization.
- No request for identity numbers or account access.
Try this
Help me rewrite this message without private details. Replace every name, account number, address, health detail, and family detail with a clear placeholder in square brackets. Do not guess what the missing information is: [paste a version you have already checked for secrets].
Check the text yourself before pasting it. If it still contains something sensitive, remove it first.
Common mistakes
- Sharing a full document when a summary would workDescribe the part you need help with and remove names, numbers, and identifying details.
- Assuming a friendly chat is privateThe tool is a company service, even when the conversation feels personal.
- Trusting one privacy setting foreverSettings and product choices can change. Review the current explanation inside the tool.
- Uploading someone else's informationDo not share private family, customer, student, patient, or employee information without proper permission.
- Using AI for a sensitive final decisionFor health, legal, financial, or safety decisions, use a qualified person or official source.

It can be used for ordinary tasks, but you should still protect private information and check important answers. Use the official service and review its current privacy and data settings.
Can I paste my password into an AI chat?
No. Never share a password, sign-in code, or security answer in an AI chat.
Can I upload a medical record?
A general consumer AI chat is not the place for a private medical record. Ask a general question without names or identifying health details, and use a qualified professional for medical advice.
What can I use instead of real information?
Use clear placeholders such as [customer name], [account], or [date]. You can also describe the situation in general terms.
Where are the privacy settings?
Look in the tool's settings for privacy, data controls, history, memory, or training. The exact names can change, so use the current help information from that tool.
What if I already shared something sensitive?
Stop sharing more. Change an exposed password or sign-in code through the official service, contact the relevant bank or organization when financial information is involved, and use the tool's current help options to manage the conversation or account.
