Does ChatGPT Save Your Conversations? Full Privacy Guide

Does ChatGPT save conversations?

Yes, ChatGPT can save standard conversations in your account history so you can return to them later. You can delete chats, turn off the use of new conversations for model improvement, manage ChatGPT Memory separately, or use Temporary Chat. Deleted and Temporary Chats are generally scheduled for deletion within 30 days, subject to limited legal and security exceptions.

Does ChatGPT Save Conversations? Privacy & Chat History Explained

ChatGPT normally saves standard conversations to your account history until you delete them. Saving a conversation is different from using it for AI model training. Users can turn off model improvement, manage ChatGPT Memory, delete conversations or use Temporary Chat. Temporary Chats do not appear in normal history, do not create or use memories, and are not used for model training.

Does ChatGPT Save Conversations?

Yes, ChatGPT can save conversations, but the complete answer depends on how you use the service, which privacy settings you have selected, whether you use a normal or temporary chat, and whether you later delete the conversation.

In a standard ChatGPT conversation, your chat will normally appear in your conversation history so you can return to it later. That is why you may see previous discussions listed in the sidebar or available through chat history across supported devices. Think of it like a digital notebook: unless you choose a mode designed to be temporary or manually remove a conversation, the discussion may remain associated with your account and available for you to revisit.

The important detail is that saving a conversation is not the same thing as using that conversation to train an AI model. These are separate issues controlled in different ways. A conversation may remain in your history even if you have switched off the setting that allows new chats to be used for model improvement.

Likewise, using Temporary Chat changes several things at once: the conversation does not appear in normal history, does not create or use memories, and is not used to train OpenAI’s models. OpenAI’s current privacy information also says that users can download their chats, delete conversations and control whether content may contribute to model improvement. (OpenAI)

So, if you searched for “does ChatGPT save conversations?”, the simplest answer is yes—but you have meaningful control over what happens next. You can keep chats for convenience, turn off model improvement while retaining history, use Temporary Chat for conversations you do not want in your normal history, delete individual discussions, export your data or delete your account.

The rest of this guide explains each of those choices because the privacy question is more nuanced than a simple yes or no.

Quick Answer: Yes, ChatGPT Can Save Your Chats

When you start a standard conversation while signed into ChatGPT, the service can keep that conversation in your chat history. This makes ChatGPT more practical because you can return to an old research session, continue writing an article, revisit a plan or pick up a discussion where you left off.

Without saved conversations, every interaction would feel like writing on a whiteboard that is wiped clean the moment you leave the room. For many users, conversation history is one of the features that makes an AI assistant useful for ongoing work rather than just one-off questions.

However, there are several separate concepts that people often mix together. Chat history refers to conversations available in your account. Model improvement concerns whether eligible content may be used to help improve AI systems. Memory concerns information ChatGPT may use to personalise future interactions.

Temporary Chat is a privacy-focused mode that behaves differently from a standard conversation. Understanding those differences is the key to answering questions about whether ChatGPT keeps, remembers or learns from what you type.

According to current OpenAI information, users have controls for temporary chats, data usage and memory. Temporary conversations are designed not to appear in normal history, not to create or use memories, and not to be used for training.

OpenAI also states that users can turn off the setting that allows future conversations to contribute to model improvement while still keeping ordinary chat history. This means you do not necessarily have to choose between keeping useful conversations and controlling training use. (OpenAI)

The practical answer, then, is straightforward: normal chats can be saved, but you have several ways to control them. If you want easy access later, use a standard conversation. If you want a conversation excluded from normal history and model training, Temporary Chat may be more suitable. If you want to remove an existing conversation, delete it rather than merely assuming that closing your browser has erased it.

Where Are ChatGPT Conversations Stored?

ChatGPT conversations are not simply stored as text files on your laptop or phone. When you use the online service, information is processed through OpenAI’s systems so the service can respond to your prompts and provide account features such as conversation history.

This is why signing into the same account on another supported device may allow you to access your existing chats. The experience is closer to web-based email than to a document saved only on one computer: your account provides access to information managed through the service.

OpenAI’s privacy policies explain that personal data may be processed to provide, maintain, analyse and improve services, personalise experiences where applicable, communicate with users and meet safety, security and legal obligations. The exact handling of data can depend on the product, account type, settings and applicable law.

For users in the European Economic Area, Switzerland and the United Kingdom, OpenAI publishes European privacy information explaining available controls, including the ability to export history, delete or archive chats and use Temporary Chat. (OpenAI)

It is also important to distinguish the conversation itself from data on your own device. Your browser may retain login information, cached content or browsing records depending on your browser settings, but that is a separate privacy issue from ChatGPT’s account-level conversation history.

Deleting your browser history does not automatically mean that a conversation has been deleted from your ChatGPT account. Similarly, closing a tab or switching off your computer does not normally delete a standard chat.

If privacy matters for a particular discussion, do not rely on assumptions about where the text “lives.” Use the controls provided for the purpose you actually have in mind. Delete the conversation if you no longer want it retained in your account, review Data Controls if you are concerned about model improvement, review Memory settings if you are concerned about personalisation, and consider Temporary Chat before beginning a conversation you do not want placed in normal history.

How Long Does ChatGPT Save Conversations?

For ordinary ChatGPT conversations, the key point is that chats you keep remain associated with your account until you choose to delete them, subject to the applicable service and retention policies.

There is no universal rule saying that every normal conversation automatically disappears after a few days. This is why users can often return to older discussions long after they were created. If you want a normal conversation removed, you generally need to delete it rather than wait for it to vanish automatically.

Once a chat is deleted, the situation changes. OpenAI’s current retention information says deleted chats are scheduled for permanent deletion from its systems within 30 days, unless the content has already been de-identified and disassociated from your account or OpenAI must keep it for longer for security or legal reasons.

The current European privacy policy similarly states that, after a user chooses to delete personal data, it is removed within 30 days unless longer retention is necessary or permitted under the circumstances described in the policy. (OpenAI Help Center)

Temporary Chats follow a different path. They do not appear in ordinary chat history and are automatically deleted from OpenAI’s systems within 30 days. This is an important distinction because “temporary” does not necessarily mean the data ceases to exist the instant you close the window. A better analogy is a hotel room scheduled for checkout rather than a message written in disappearing ink: it is designed not to become part of your permanent normal history, but a limited retention period may still apply.

The answer to how long ChatGPT saves conversations, therefore, depends on what you do. A normal chat you keep can remain in your history. A deleted chat is generally scheduled for removal within the stated deletion period, subject to limited exceptions. A Temporary Chat is automatically deleted within 30 days.

Knowing which type of conversation you are using gives you a much clearer answer than treating every ChatGPT interaction as though it follows one identical storage rule.

What Happens When You Delete a Chat?

Deleting a ChatGPT conversation is different from simply hiding it, closing it or archiving it. When you delete a chat, it is removed from your visible history and scheduled for permanent deletion from OpenAI’s systems within the applicable retention period.

Current OpenAI documentation states that deleted chats are scheduled for deletion within 30 days unless they have already been de-identified and disassociated from the user or need to be retained longer for security or legal reasons. (OpenAI Help Center)

This is one reason you should think carefully before pressing delete. A deleted conversation should not be treated like a document moved into a recycle bin that you can casually restore later.

If the chat contains research, writing, business notes or other information you may need, copy or export what matters before removing it. OpenAI provides data export options through account controls, which can be useful if you want your own copy of account data before making major changes.

Another important detail involves ChatGPT Memory. Deleting a conversation does not necessarily mean that a separately saved memory connected with information from that conversation has also been removed.

OpenAI has explained that saved memories and chat history are separate systems. If you want ChatGPT to stop retaining a saved memory, you may need to delete that memory through the relevant Personalisation or Memory controls, as well as remove the original chat.

This distinction catches many users by surprise. Imagine tearing a page out of a diary after separately copying one fact from that page onto a reminder card. Destroying the diary page does not automatically destroy the reminder card.

In the same way, deleting a conversation and managing saved memories can require separate actions. If your goal is a thorough privacy clean-up, review both your conversation history and your memory settings rather than assuming one control automatically manages everything.

Can OpenAI Keep Deleted Conversations for Longer?

Under normal deletion procedures, OpenAI says deleted personal data is removed from its systems within 30 days, but there are stated exceptions. Information may need to be kept for longer where retention is required for legal, safety or security reasons.

This type of exception is not unique to AI services; online platforms may face obligations connected with fraud prevention, legal disputes, regulatory requirements, abuse investigations and other legitimate circumstances. The important point is that the 30-day period should not be interpreted as an absolute promise that no exceptional situation could ever require longer retention. (OpenAI)

There was also considerable public discussion in 2025 about a legal order connected with litigation involving The New York Times. That situation caused confusion because some people assumed ChatGPT had permanently changed its standard retention practices for everyone.

OpenAI later stated that the obligation under the earlier order ended in September 2025 and that it had returned to standard data retention practices. This is a useful reminder that privacy claims can change when legal circumstances change, which is why current official information matters more than old social media posts or outdated articles. (OpenAI)

For an everyday user in 2026, the practical rule remains simple: if you delete a chat, expect it to disappear from your account and enter the normal deletion process, but understand that limited exceptions may apply. Do not use ChatGPT as the only storage location for something you need permanently, and do not assume that deletion is instantaneous at the infrastructure level.

Privacy policies can sound intimidating because they have to cover unusual situations as well as normal ones. The best approach is to focus on the controls you can use: avoid entering highly sensitive secrets, use Temporary Chat when appropriate, delete unwanted conversations, manage memory separately and keep your account secure.

Those actions provide more meaningful protection than worrying about unlikely scenarios while ignoring everyday privacy habits.

Does ChatGPT Use Your Conversations for Training?

Some ChatGPT conversations may be used to improve models depending on the product and your settings, but users have controls over this. 

OpenAI states that chat data can help improve model quality, while also providing a setting that allows users to turn off the use of future conversations for model improvement. On personal ChatGPT workspaces, the relevant control is commonly labelled “Improve the model for everyone.” When this is switched off, new conversations will not be used to train OpenAI’s models. (OpenAI)

This is where many online explanations become inaccurate. Saving a conversation in your history and using a conversation for model improvement are not identical actions. You can keep chat history while switching off model training for new conversations.

That separation matters because a user may want the convenience of returning to past chats without wanting new content to contribute to model improvement.

OpenAI’s May 2026 explanation of privacy and training says that model development uses a mixture of publicly available information, partnership data and information provided or generated by users, contractors and researchers. It also describes safeguards intended to reduce personal information in training data, including privacy filtering.

For user conversations, the article specifically connects potential training use with whether “Improve the model for everyone” is enabled.

The safest mindset is still to avoid treating any general-purpose online AI service as a vault for secrets. Even when you have disabled training, that setting addresses model improvement; it does not transform a standard cloud service into an offline notebook. If a piece of information would cause serious harm if exposed—such as a password, full payment-card details or highly confidential business secrets—the better decision is usually not to paste it into a consumer chat service in the first place.

How to Stop New Chats Being Used for Model Improvement

If you want to keep your ChatGPT history but do not want new personal-workspace conversations used to improve models, OpenAI provides specific data control. Current official instructions direct users to open their profile, go to Settings, select Data Controls, find Improve the model for everyone, and switch the setting off.

OpenAI states that after opting out, new conversations will not be used to train its models.

This setting is useful because it separates two choices that users often assume are bundled together. You can value saved conversation history and still decide against allowing future chats to contribute to model improvement.

Picture two switches on a wall rather than one master switch: one controls whether you can return to your conversation, while another controls whether eligible content may be used for improving models.

Temporary Chat offers another option for individual conversations. OpenAI says Temporary Chats do not appear in history, do not create or use memories and are not used to train models. This may be useful when you normally want conversation history but occasionally have a discussion you do not want treated like an ordinary saved chat.

(OpenAI) Settings and interfaces can evolve, so it is sensible to review your privacy controls occasionally rather than assuming a choice you made years ago still reflects how you want to use the service today. OpenAI’s consumer privacy information presents Temporary Chat, Data Controls, Memory Controls and data deletion or export as separate tools. Understanding each one lets you choose the right control for the right concern instead of switching off useful features unnecessarily.

What Is Temporary Chat in ChatGPT?

Temporary Chat is a privacy-focused conversation mode designed for discussions you do not want placed in your normal chat history. According to current OpenAI information, Temporary Chats do not appear in history, do not create or use ChatGPT memories and are not used to train OpenAI’s models. They are also automatically deleted from OpenAI’s systems within 30 days.

This makes Temporary Chat useful for one-off questions that you do not need to revisit. Perhaps you want help rewriting a private draft, brainstorming a temporary project or asking a question that has no value in your long-term conversation history. Rather than creating a standard chat and remembering to delete it later, you can start in a mode designed to be temporary from the beginning.

However, users should understand what Temporary Chat does not mean. It does not mean that the conversation is guaranteed to disappear from all systems the instant you close the chat. OpenAI’s retention policy states that Temporary Chats are automatically deleted within 30 days. The distinction matters because the word “temporary” can create an image of a self-destructing message, while the actual policy describes a limited retention process. (OpenAI Help Center)

Temporary Chat is best understood as a tool for controlling history, memory and model improvement rather than as permission to share anything whatsoever. You should still avoid entering passwords, authentication codes, full financial credentials and other information that does not need to be shared. Privacy features reduce unnecessary retention and use; good judgement reduces unnecessary exposure in the first place.

How Temporary Chat Changes Conversation Storage

A standard ChatGPT conversation can remain available in your account history until you delete it. Temporary Chat changes that experience by keeping the discussion out of normal history and placing it on an automatic deletion path.

OpenAI currently says Temporary Chats are deleted from its systems within 30 days. This gives users a practical middle ground between maintaining a permanent-looking history and manually deleting every one-off discussion. (OpenAI Help Center)

Temporary Chat also affects personalisation. The conversation does not create new memories or use existing memories in the normal way described for personalised chat experiences. That can be useful when you want a clean-slate conversation that is not influenced by information ChatGPT may otherwise use to personalise responses.

The feature also changes model-training treatment. OpenAI states that Temporary Chats are not used to train models. This combination—no normal history, no memory use or creation and no model training—explains why Temporary Chat is one of the most relevant features for anyone searching “does ChatGPT save conversations?” The answer is not just about whether the platform saves chats; it is about which conversation mode you choose.

For routine work you want to continue later, a normal chat may be more convenient. For a one-time discussion you do not need in your sidebar, Temporary Chat may make more sense. The choice is similar to deciding whether to write something in a permanent notebook or on a temporary scratchpad. Both can help you think, but they are designed for different purposes.

Is Chat History the Same as ChatGPT Memory?

No. Chat history and ChatGPT Memory are related but different features. Chat history is the collection of conversations you can return to, while memory is designed to help ChatGPT retain or use relevant information across conversations for personalisation. A user might have hundreds of old conversations without ChatGPT treating every sentence in every chat as a permanently saved memory.

OpenAI’s Memory FAQ explains that ChatGPT does not retain every detail from past chats and distinguishes saved memories from broader chat-history reference features. Saved memories can include details intended to be useful in future conversations, while chat history provides another source of context where supported and enabled. The exact personalisation features available can depend on the user’s settings, plan and product experience.

This difference matters for privacy management. Deleting a chat is not always the same as deleting a saved memory. OpenAI has explicitly explained that memories can exist separately from the original conversation, meaning a user who wants information fully removed from personalisation may need to manage both the chat and the memory. (OpenAI)

Think of chat history as a bookshelf and memory as a set of notes taken from selected books. Removing one book from the shelf does not automatically destroy a separate note card created from something written in that book. If your goal is simply to clean up your conversation list, delete or archive chats as appropriate. If your goal is to stop ChatGPT from using a remembered detail, review Memory controls as well.

Can ChatGPT Remember Information After You Delete a Conversation?

Potentially, yes, if information from the conversation exists as a separate saved memory. This is one of the most important details for anyone managing ChatGPT privacy.

OpenAI has explained that deleting a chat does not automatically erase saved memories created from that conversation. To remove the remembered information, you may need to delete the relevant saved memory separately.

This does not mean that every deleted chat remains secretly available as a memory. ChatGPT does not simply convert every word you type into a permanent personal fact. The point is narrower: conversation deletion and memory deletion are separate controls. If a detail has been saved or retained through the memory system, removing the original chat alone may not be enough to remove that separate memory.

Users who want greater control can review, edit or delete saved memories and can turn memory features off. OpenAI’s consumer privacy page states that memory is optional and provides controls for reviewing, editing, deleting or disabling it.

A practical privacy check, therefore, has two parts. First, review your chat history and delete conversations you no longer want. Second, review your Personalisation or Memory settings and remove saved information you no longer want ChatGPT to use. Treating these as separate cupboards to clean is much more effective than emptying one and assuming the other must also be empty.

Can You Delete ChatGPT Conversations Permanently?

Yes, users can delete ChatGPT conversations. Current OpenAI retention information states that deleted chats are scheduled for permanent deletion from its systems within 30 days, unless they have already been de-identified and disassociated from the account or must be retained for longer for legal or security reasons.

This means deletion is a real account control, but the back-end process is not necessarily instantaneous. (OpenAI Help Center)

If you are deleting a chat because it contains something important, remember that deletion can be difficult or impossible to reverse. Save anything you need first. If you want a broader record, OpenAI provides a data export option through Data Controls. This can be useful for people who have used ChatGPT for long-term projects, research or writing and want a personal copy before cleaning their account.

Deleting an individual conversation is also different from deleting your entire account. Account deletion is a much larger action and should not be used merely because you want to remove one embarrassing question or old project. Use the smallest control that achieves your goal.

The central lesson is that users are not powerless over saved chats. You can remove individual conversations, manage memories, export data, use Temporary Chat and, where appropriate, delete your account. The challenge is simply knowing which control corresponds to the privacy outcome you actually want.

Deleting, Archiving and Exporting Your Chats

Deleting, archiving and exporting are three different actions. Deleting is for conversations you want removed. Archiving is primarily an organisational action that can remove clutter from your main chat list without treating the conversation as deleted.

Exporting creates a copy of your data for your own records. Choosing the wrong option can lead to confusion, especially when someone archives a chat and assumes it has been erased.

If privacy is your goal, deletion is the relevant action rather than archiving. If organisation is your goal, archiving may be more suitable because you can reduce sidebar clutter without throwing away useful work. If you are preparing to delete a large amount of content or close an account, exporting first may give you a useful backup.

OpenAI’s current privacy information confirms that users can export ChatGPT history and data through account controls and can delete or archive chats. Its ChatGPT FAQ directs users to Settings → Data Controls → Export for data export. (OpenAI)

Think of the three options as a filing cabinet. Archiving moves a document to another drawer. Exporting photocopies for your own records. Deleting sends it into the removal process. Once you understand that distinction, managing ChatGPT conversation history becomes much simpler.

Are ChatGPT Conversations Private?

ChatGPT provides privacy and security controls, but users should not interpret the word “private” as meaning that a standard cloud-based AI conversation is identical to an offline diary locked in a safe.

OpenAI processes information to provide the service and describes various purposes and safeguards in its privacy policies. Users also have controls over training, memory, temporary conversations, data export and deletion. (OpenAI)

Your own account security also matters. A carefully configured privacy setting cannot protect a conversation if someone gains access to your account or an unlocked device. Use a strong, unique password, secure your email account and enable stronger authentication options where available.

Shared computers deserve particular care because leaving an account signed in can expose conversation history to the next person who uses the device.

You should also consider the content you choose to enter. Privacy controls are valuable, but data minimisation is even simpler: if ChatGPT does not need a secret to help you, do not provide the secret. You can often replace real names with placeholders, remove account numbers, redact confidential client information and describe a problem without pasting the entire sensitive document.

The sensible approach is not to panic and not to blindly trust. Use the service for the tasks it is designed to help with, understand the controls available to you and avoid unnecessary disclosure. That balance lets you benefit from AI without treating every prompt as either completely public or magically invisible.

Should You Share Passwords or Sensitive Information With ChatGPT?

You should not share passwords, authentication codes, private keys or other credentials in ChatGPT. There is rarely a legitimate reason for an AI assistant to know your actual password. If you need help creating a stronger password policy, troubleshooting a login process or understanding an error, describe the problem without providing the secret itself.

The same principle applies to sensitive personal and business data. Before pasting a document, ask whether ChatGPT needs every detail. Could you replace a customer’s name with “Client A”? Could you remove a home address? Could you show only the relevant paragraph of a confidential report? Privacy often improves dramatically when you share the minimum information necessary.

Financial and identity information deserves similar care. Avoid pasting full payment-card details, bank login credentials, government identification numbers or security answers into a general chat. Even if you have adjusted training settings, minimising unnecessary exposure remains a strong habit.

A useful rule is this: if the AI does not need the secret to answer the question, remove the secret before sending the prompt. This takes only a few seconds and works across almost every online service, not just ChatGPT. Privacy settings are the locks on the door; careful data sharing is deciding what valuable items you bring into the room.

Do Business and Enterprise ChatGPT Accounts Save Conversations Differently?

Business-oriented ChatGPT products have different data commitments from personal consumer workspaces. OpenAI states that, by default, it does not use data from ChatGPT Business, ChatGPT Enterprise, ChatGPT Edu and its API platform to train or improve models. This distinction is particularly important for organisations evaluating AI for internal work, as business data governance requirements often differ from those of an individual asking everyday questions.

That does not mean every organisation should assume that all business use is automatically risk-free. Companies still need their own policies covering what employees may upload, which accounts they should use, how confidential data is classified and how access is managed. A secure enterprise product can still be used badly if staff paste information into the wrong workspace or ignore internal rules.

Organisations should also examine retention and compliance requirements rather than focusing only on training. A regulated business may need specific controls for record keeping, legal holds, data residency, access logging or deletion. OpenAI provides business privacy, security and compliance information for organisations evaluating those needs.

For an individual user, the key takeaway is that an answer about personal ChatGPT should not automatically be copied into a corporate context.

Consumer accounts and business products can have different defaults and commitments. If you use ChatGPT for work, follow your employer’s approved tools and policies rather than assuming your personal settings apply to company information.

How to Make Your ChatGPT Conversations More Private

You do not need to stop using ChatGPT to improve your privacy. A few deliberate choices can make a substantial difference. The most useful first step is to review Settings, particularly

Data Controls and Personalisation or Memory options. Decide whether you want new conversations to contribute to model improvement, whether you want memory enabled and whether old saved memories still make sense.

For conversations you do not want in normal history, consider Temporary Chat. For existing chats you no longer need, delete them rather than merely closing the browser. If a conversation led to a saved memory you no longer want used, manage that memory separately. OpenAI’s current privacy resources specifically provide controls for temporary conversations, training preferences, memory and deletion.

You can also improve privacy before the conversation begins. Remove unnecessary names, contact details, account numbers and confidential identifiers from prompts. Summarise sensitive documents instead of uploading the entire file when the full text is not required. Use placeholders for real people and businesses where their identity is irrelevant to the answer.

Finally, protect the account itself. Sign out of shared devices, secure the email account connected to your login and review account security options. Privacy is a chain, and the weakest link may not be AI training or data retention at all—it may simply be an unlocked laptop in a public place. Good privacy comes from combining sensible settings, careful sharing and strong account security.

Conclusion

So, does ChatGPT save conversations? Yes, standard ChatGPT conversations can be saved in your account history, allowing you to return to them later. However, that simple answer hides several important distinctions. Saved chat history is not the same as model training, and neither is it identical to ChatGPT Memory. Users have separate controls for these different parts of the experience.

Current OpenAI information says users can turn off the use of new personal-workspace conversations for model improvement while keeping chat history.

Temporary Chats do not appear in normal history, do not create or use memories and are not used for model training; they are automatically deleted from OpenAI’s systems within 30 days. Deleted standard chats are also scheduled for permanent deletion within 30 days, subject to stated exceptions such as legal or security requirements. (OpenAI Help Center)

The most important privacy habit is to use the correct control for the correct concern.

Delete a chat when you want it removed. Manage Memory when you want ChatGPT to stop using a remembered detail. Switch off model improvement if you do not want new eligible personal-workspace conversations used for training. Use Temporary Chat when you want a one-off conversation outside normal history.

Above all, avoid sharing information the AI does not need. Passwords, authentication codes and unnecessary confidential details should stay out of prompts. ChatGPT offers useful privacy controls, but the strongest approach combines those controls with careful judgement about what you type in the first place.

Frequently Asked Questions

Five Common Questions About Saved ChatGPT Conversations

1. Does ChatGPT save every conversation?

Standard conversations can remain in your account history, but not every chat follows the same rules. Temporary Chats do not appear in normal history and are automatically deleted within 30 days. Your exact experience can also depend on your settings and the product you are using.

2. How long does ChatGPT keep deleted conversations?

OpenAI currently says deleted chats are scheduled for permanent deletion from its systems within 30 days. Exceptions may apply if the information has already been de-identified and disassociated from the account or needs to be retained longer for legal or security reasons.

3. Can I stop ChatGPT from using my conversations for training?

Yes. On eligible personal workspaces, you can go to Settings → Data Controls → Improve the model for everyone and switch the setting off. OpenAI says new conversations will then not be used to train its models.

4. Does deleting a chat also delete ChatGPT Memory?

Not necessarily. Chat history and saved memories are separate. If information has been saved as a memory, you may need to delete the memory separately, as well as delete the original conversation.

5. Is Temporary Chat completely private?

Temporary Chat offers additional privacy controls because it does not appear in normal history, does not use or create memories and is not used to train models. However, OpenAI says Temporary Chats are automatically deleted from its systems within 30 days, so “temporary” should not be interpreted as instant deletion.
