How to Stop ChatGPT Training on Your Data

The Exact Steps to Turn Off Model Training

OpenAI puts the control in one place. On Free, Plus, and Pro accounts, training is on by default, so you have to switch it off yourself. The setting is called Improve the model for everyone, and it lives under Data Controls. Once you flip it off, new conversations stop feeding OpenAI's training runs.

The change applies to your whole account, not just the chat you have open. It takes effect for conversations going forward, so anything already used in a past training run cannot be pulled back out.

• Step 1: Open ChatGPT and click your profile, then Settings.
• Step 2: Select Data Controls in the settings menu.
• Step 3: Find the toggle labeled Improve the model for everyone.
• Step 4: Switch the toggle off.
• Step 5: Confirm the toggle now reads as disabled. The setting applies across your entire account.

Does Turning It Off Delete Your Chat History?

No. This is the part that confuses most people. An older version of ChatGPT bundled training and history into a single switch, so turning off training also wiped saved conversations. That is no longer how it works.

Today the Improve the model for everyone toggle is separate from chat history. You can disable training and still keep every past and future conversation visible in your sidebar. Your day-to-day experience does not change. ChatGPT answers the same way, remembers what you allow it to remember, and keeps your history exactly where it was.

If you want a record of what you typed and you also want to stay out of training, this is the combination to use: history on, training off.

• Disabling training does not hide or delete your chat history.
• History and training are independent settings now, not one switch.
• Your normal ChatGPT experience stays the same after opting out.

Temporary Chat: A Stronger Per-Conversation Option

Some conversations are sensitive enough that you do not want them saved at all. Temporary Chat handles those. Start one from the model picker, and the session behaves like a clean slate. It will not appear in your history, it will not read from or write to memory, and it will not be used to train OpenAI models.

Temporary Chats are not kept forever. OpenAI deletes them from its systems within 30 days. The trade-off is that ChatGPT forgets the conversation the moment you close it, so it suits one-off questions rather than ongoing projects.

Temporary Chat works even when your account-wide training toggle is still on, which makes it a useful per-conversation override for anything you want kept out of training and out of memory.

• Temporary Chat skips history, memory, and model training.
• Sessions are deleted from OpenAI systems within 30 days.
• Use it for sensitive one-off questions, not long-running work.
• It overrides training on a single conversation, even if the global toggle is on.

Free and Plus Versus Team, Enterprise, and Edu

The defaults differ by plan, and this matters. On consumer plans, Free, Plus, and Pro, OpenAI uses your conversations to improve its models unless you opt out. The opt-out is the toggle described above.

Business and education plans flip that default. ChatGPT Team, ChatGPT Enterprise, ChatGPT Edu, and the API platform are not used to train OpenAI's models by default. Enterprise and Team accounts also sit under contractual data processing terms that bar OpenAI from training on organizational data. If you are on one of these plans, there is no per-user training toggle to chase, because the protection is already in place at the account level.

If you are unsure which plan you are on, check your subscription details. A personal paid Plus account is still a consumer plan and trains by default until you opt out.

• Free, Plus, and Pro: training is on by default, opt out manually.
• Team, Enterprise, Edu, and the API: not trained on by default.
• Business and Enterprise data is covered by contractual terms, not just a toggle.
• A personal Plus subscription is consumer-tier, so the opt-out still applies to you.

What Opting Out Does and Does Not Cover

Opting out stops future conversations from entering training runs. It does not retroactively remove data already used. It also does not stop OpenAI from retaining logs for operational or legal reasons. In 2025 a federal court order in the New York Times copyright case required OpenAI to preserve user logs, including some that users expected to be deleted. Retention for a legal hold is different from training, but it is a reason to treat any chatbot as a place where text can persist.

There is one more catch. If you submit feedback on a response, such as a thumbs up or down with a comment, the conversation tied to that feedback may be used to train models even when your toggle is off. Skip feedback on anything sensitive.

For information you never want sent toward a training pipeline in the first place, the cleaner approach is to keep it out of the open chat box entirely. A private-by-architecture memory layer like MemX stores your context with per-user isolation and encryption at rest, backed by Google Cloud KMS, so personal and project context stays separated by user rather than pooled into a shared conversation stream. MemX is a complement to ChatGPT, not a replacement for it: you still chat in ChatGPT, but the context you care about most lives in a space you control.

• Opting out is forward-looking and does not erase past training data.
• Logs can still be retained for operational or legal reasons.
• Submitting feedback can pull that conversation into training, toggle aside.
• MemX keeps sensitive context per user, with encryption at rest and Google Cloud KMS.

A Practical Checklist

Pick the level of control that matches your needs. For most people, flipping one toggle is enough. For sensitive work, layer Temporary Chat on top. For organizational data, the plan you choose does most of the work for you.

• Everyday privacy: turn off Improve the model for everyone in Data Controls.
• Sensitive one-offs: start a Temporary Chat for that single conversation.
• Avoid submitting feedback on private conversations.
• Organizations: use Team, Enterprise, or Edu so training is off by default.
• Keep your most personal context in a controlled memory layer instead of the open chat box.
