Before you send a prompt about someone you know, ask: Could a person familiar with the situation recognize them from these details? If so, remove or broaden details that are not needed to get a useful answer. Leaving out a name is not enough if the rest of the story points to one person.
A four-step check before you send a prompt
- Describe the task without naming the person. Start with what you need help doing, such as preparing questions for a doctor or thinking through a difficult conversation.
- Keep only context that changes the answer. Remove background details that do not affect the advice you are seeking.
- Generalize identifying details. Broaden dates, locations, job titles, relationships, and unusual circumstances. A unique combination can identify someone even when each detail seems harmless on its own.
- Leave out sensitive material unless it is genuinely necessary. Avoid sharing another person’s health records, financial information, private messages, passwords, login credentials, or confidential documents. These are examples, not a complete list of sensitive information.
For example, instead of writing, “My sister Maya, a nurse at the only clinic in [small town], was diagnosed on Tuesday with [rare condition],” you could ask, “A family member has a health concern; what questions might they ask a clinician?” Keep a detail only if it materially changes the help you need. This broader wording is an editing example, not a guarantee that the person is anonymous.
Canadian privacy commissioners recommend using anonymized or de-identified information in generative-AI prompts where possible and reasonable. They also explain that inferences about an identifiable person can count as personal information. UK government guidance warns that linking data can re-identify people thought to be anonymous. In practice, consider whether someone who knows the people or events could work out who you mean—not just whether you included a name.

Be especially cautious with someone else’s private material
A tool’s ability to accept an upload does not mean a document, image, or message is appropriate to share. Before uploading someone else’s private material, ask whether you have a clear need and an appropriate basis to share it. If a summary or general question will work, use that instead of supplying the original.

Anthropic’s guidance specifically identifies financial information, health records or medical information, passwords or private login credentials, and confidential business or personal documents as information to handle thoughtfully.

Privacy settings limit particular uses; they do not make prompts anonymous
Settings can affect whether conversations are used for model training or improvement, appear in history, or are retained. Their effects differ by service, and a setting that limits one use does not mean the prompt contains no personal information or receives no processing to provide the service. The descriptions below reflect the cited provider pages as checked on October 4, 2026. Product names, menus, defaults, retention practices, and rules may change or vary by location and account type; check the current controls and privacy notice for the account you use.

Privacy-law duties depend on jurisdiction and context. The Canadian commissioners’ principles and CNIL’s English courtesy translation discuss responsible organizational handling of personal data; they do not provide a universal legal test for whether an individual may disclose another person’s information in an everyday prompt. CNIL’s translation, dated January 5, 2026, describes transparency principles and notice duties for organizations handling directly or indirectly collected personal data in AI development. If the matter is consequential, check your organization’s policy and seek jurisdiction-specific advice rather than relying on a consumer privacy setting.
