# Is ChatGPT safe for confidential information?

ChatGPT can be safe for confidential information on a business plan with the right settings, but a personal account on default settings is a poor place for it. On Free, Go, Plus and Pro, OpenAI may use your chats to train its models unless you opt out, and authorized staff and contractors can access content in defined cases. ChatGPT Business, Enterprise, Edu and the API do not train on your data by default, though each still keeps some data for a period and remains subject to legal process.

## What happens to what you type, by plan

The rules on training, retention and access differ by plan. The table below summarizes OpenAI's own policy pages as of October 2026.

| Plan | Used for training by default | How long content is kept | Who at OpenAI can access it |
|---|---|---|---|
| Free, Go, Plus, Pro (personal) | Yes, unless you turn off "Improve the model for everyone" | Saved chats stay until you delete them. Deleted chats are scheduled for permanent deletion within 30 days, with exceptions for security and legal obligations | Limited authorized personnel and service providers, for abuse or security investigations, support, legal matters, and model improvement |
| Temporary Chat (any personal plan) | No, while it stays temporary | A copy may be kept for up to 30 days for safety purposes | Same as above |
| ChatGPT Business (previously Team) | No | Workspace admins set retention. Deleted or unsaved chats are removed within 30 days unless law or harm prevention requires longer | Authorized employees for engineering support, abuse investigation and legal compliance, plus contractors who review for abuse and misuse |
| ChatGPT Enterprise and Edu | No | Workspace admins set retention. Deleted chats are removed within 30 days unless law requires otherwise | Authorized employees only to resolve incidents, recover conversations with your permission, or where law requires |
| API Platform | No | Abuse monitoring logs kept up to 30 days by default. Approved customers can get Zero Data Retention on eligible endpoints | Authorized employees and contractors bound by confidentiality, for abuse and misuse review |

A few details sit outside the table. Turning off training does not delete anything: your saved chats stay in history until you remove them. If you rate a response with a thumbs up or thumbs down, OpenAI says the whole conversation tied to that feedback may be used for training, even after you opt out.

On the API, Zero Data Retention requires prior approval from OpenAI. It keeps your content out of abuse monitoring logs, and some endpoints, such as Assistants and Threads, are ineligible and still store data until you delete it. Our guide to [zero data retention AI](/guides/zero-data-retention-ai/) covers how ZDR works across providers.

## The risks that matter for confidential information

**Training.** On a personal plan with default settings, your prompts, files and images can feed future models. Once content has been used for training, you cannot pull it back.

**Human access.** OpenAI's consumer help center states that authorized personnel and trusted service providers may access content to investigate abuse, provide support, handle legal matters, or improve model performance. The same page asks you not to enter sensitive information you would not want reviewed or used.

**Litigation and preservation.** In May 2025, a federal court in the New York Times copyright case ordered OpenAI to preserve ChatGPT output logs that would otherwise have been deleted. That obligation ended on September 26, 2025. OpenAI says it still holds limited historical user data from April to September 2025 under legal hold, and Engadget reported in October 2025 that OpenAI must keep data tied to accounts the Times has flagged. In January 2026, Judge Sidney Stein affirmed an order requiring OpenAI to produce a sample of 20 million de-identified chat logs to the plaintiffs. OpenAI said Enterprise, Edu and Zero Data Retention API traffic fell outside the original order. The lesson for you: a 30-day deletion promise can be suspended by a court, and your chats can become evidence in a case you are not part of.

**Memory.** When Memory is on, ChatGPT can draw on past chats, saved memories, files in Library and connected apps such as Gmail. Deleting a chat does not delete a saved memory created from it, and OpenAI may keep logs of deleted memories for up to 30 days. A detail you shared once can resurface in a later answer.

**Third parties.** If a custom GPT sends data through an action, the receiving company's privacy policy governs that data, and it may keep it longer than 30 days.

## A practical checklist before you paste

- Use a business workspace (Business, Enterprise or Edu) for any client, deal or family matter. Confirm with your admin what retention period is set.
- On a personal account, open Settings, then Data controls, and turn off "Improve the model for everyone." Or select "Do not train on my content" in the OpenAI Privacy Portal.
- Use Temporary Chat for one-off questions you do not want in history or memory, and remember a copy may persist for up to 30 days.
- Avoid the thumbs up and thumbs down buttons on sensitive conversations.
- Review Settings, then Personalization, then Memory. Turn Memory off or delete saved memories that contain names, figures or account details.
- Delete sensitive chats, files in Library, and saved memories one by one, since deleting one does not remove the others.
- Strip names, account numbers and identifying terms before you paste, and summarize documents instead of uploading originals where you can.
- Check whether connected apps (email, drive, calendar) are necessary, and disconnect the ones you do not use.
- For legal or regulated work, read your engagement terms and professional rules before any client data leaves your systems.

## When you need more than a setting change

Every control above reduces exposure at one point: training, history, or memory. Your data still passes through a provider's servers, sits in its logs for a period, and stays reachable by its staff and by courts. For a family office, a law firm or an executive office, the question extends past the model to where memory lives, who can act on your accounts, and where the system runs. That broader design goal is called [private superintelligence](/what-is-private-superintelligence/).

Private SuperIntelligence from Mitosis Labs is an AI concierge for enterprises, family offices and private clients, built on six privacy layers: retention and deletion, communication, access and actions, model inference, data storage, and deployment. The provider retains nothing and trains on nothing. Intake is limited and the current intake is fully subscribed; you can [register interest](/#waitlist) for the next one.

## Frequently asked questions

### Does ChatGPT store my data?

Yes. Saved chats on a personal account stay until you delete them, and deleted chats are scheduled for permanent deletion within 30 days unless OpenAI must keep them for security or legal reasons. Business, Enterprise and Edu workspaces let admins set retention, and API logs are kept up to 30 days by default.

### Can I put confidential data into ChatGPT?

You can on a business plan whose terms your organization has reviewed, with Memory and connected apps set to match your policies. On a personal account, OpenAI's own help center asks you not to enter sensitive information you would not want reviewed or used, so treat client and financial data as off limits there.

### Is ChatGPT private if I turn off training?

Turning off training stops new conversations from being used to train models, but it does not delete chat history or end human access for abuse, support or legal purposes. Your content also stays subject to court orders, as the New York Times preservation order showed in 2025.

### Is Temporary Chat private?

Temporary Chat keeps the conversation out of your history, does not create memories, and is not used for training while it stays temporary. OpenAI may still keep a copy for up to 30 days for safety purposes, and saving the chat converts it into a regular one.

### Is ChatGPT Enterprise safe for confidential information?

Enterprise does not train on your data by default, lets admins control retention, and limits OpenAI employee access to incidents, permitted recovery and legal requirements. It also has SOC 2 Type 2 attestation and a Data Processing Addendum, which makes it a stronger fit than a personal account, though data still resides with OpenAI.
