Frequently asked questions

Most people who use ChatGPT every day have never read OpenAI’s privacy policy. Privacy policies are long, dense, and written by legal teams whose job is precision rather than clarity. But the gap between what users assume about their conversations and what OpenAI actually does with them is real, and it matters.

This guide explains it in plain English, without panic and without dismissing the concerns. The goal is simple: give you an accurate picture, practical options, and an honest assessment of what tools (including VPNs) can and can’t help with when privacy is on the line.

The plain-English answer: yes, and here’s what that means

Yes, ChatGPT stores your conversations. By default, they’re saved in your account indefinitely. OpenAI may use them to train future AI models unless you opt out. When you delete them, they remain on OpenAI’s internal systems for up to 30 days. Even in the most privacy-friendly setup, some retention still happens.

When you type something into ChatGPT, that text is sent to OpenAI’s servers. It’s processed there, and the response is generated there. By default, a record of the conversation is also stored, inside your account, so you can access it later, and so OpenAI can use it according to its policies.

That’s not automatically a “scandal.” ChatGPT uses conversation history to maintain context within a session and across sessions. Storing conversations is part of how the product works, not just an accidental side effect.

The privacy questions that matter are more specific: How long is it stored? What is it used for? Who can access it? What happens when you delete it? And can you stop it? This guide answers those questions one by one.

What exactly does ChatGPT store

ChatGPT stores the content of your conversations (your prompts and ChatGPT’s responses), metadata about your sessions (timestamps, device type, IP address), your account information, and usage data. If you use the API, operator-configured retention settings apply instead of your personal account settings.

OpenAI’s privacy policy and help documentation describe several categories of data collected when you use ChatGPT

Conversation content: Everything you type, every prompt, every follow-up question, every personal detail you share, and every response ChatGPT generates.

Session metadata: Technical information about when and how you connected: IP address, timestamps, browser or app version, device type, and general location derived from your IP address.

Account information: Your name, email address, payment details (for paid plans), and any profile information you provide

Usage and telemetry data: How you interact with the interface, what features you use, how long sessions last, what you click.

Uploaded files and images: If you upload a document, image, or file for analysis, that content is transmitted to and processed on OpenAI’s servers too. Retention rules for uploaded files can differ slightly from conversation text.

Voice input: If you use voice mode, your audio is transcribed and processed. OpenAI’s policy notes it’s used for transcription and may be retained for a period

The combination of conversation content and session metadata is the most sensitive part, because your IP address can be linked back to your identity through your ISP, and then it’s paired with what you said.

How long does OpenAI keep your conversations?

Conversations you keep in your account are stored indefinitely until you delete them. After deletion, they remain on OpenAI’s internal systems for up to 30 days. In Temporary Chat mode, conversations are deleted from your view immediately and removed from OpenAI’s systems within 30 days. Legal obligations can extend retention beyond these defaults

Standard conversations (history on, default setting): Saved indefinitely in your account. They persist until you delete them.

After you manually delete a conversation: OpenAI’s documented policy is that deleted conversations are removed from its systems within 30 days. During those 30 days, the conversation is no longer visible in your account, but it still exists on OpenAI’s infrastructure.

Temporary Chat mode: When you use Temporary Chat, the conversation isn’t saved to your account history. These conversations are deleted from OpenAI’s systems within 30 days, even without manual deletion. This is ChatGPT’s most privacy-friendly standard mode.

Legal retention exceptions: Both windows include a carve-out: “unless we are legally required to retain them.” If OpenAI receives a court order or is involved in litigation requiring retention of specific data, the 30-day window can be extended indefinitely.

Enterprise and API: Business customers using ChatGPT Team, Enterprise, or the API have different retention settings. Enterprise customers can configure zero-day retention. API users have retention governed by their service agreement, not personal account settings.

Does ChatGPT use your chats to train its AI?

The default position: On free and ChatGPT Plus accounts, OpenAI’s policy states that your conversations may be used to train and improve its AI models. In principle, the content you type could be reviewed by OpenAI staff or used as training data.

How to opt out: OpenAI provides an opt-out in account settings. Path: Settings → Data Controls → “Improve the model for everyone” → toggle off. With this disabled, your new conversations aren’t used for model training. Previously submitted conversations already used for training can’t be removed retroactively.

The caveat: Even with the training opt-out enabled, OpenAI reserves the right to review conversations for safety monitoring, abuse prevention, and policy compliance. That’s different from model training, but it does mean conversations aren’t completely off-limits to human review under any standard plan.

Enterprise and API: By default, OpenAI does not use conversations from Enterprise customers or API operators to train its models, one of the biggest privacy differences between consumer and enterprise plans

The honest framing: Opting out of model training narrows what OpenAI does with your data, not whether it holds it. Conversations are still stored, still subject to legal demands, and still reviewable under safety policies.

Who can see your conversations?

Your conversations can be seen by: you (via your account), OpenAI staff (under safety, abuse, and quality review policies), OpenAI’s AI systems (for model training, unless you opt out), and law enforcement (under valid legal process). Third-party plugins or integrations you authorize can also access conversation context.

You: Your conversation history is accessible in your account. You can read, archive, share, or delete it

OpenAI employees and contractors: Staff may review conversations for safety monitoring, abuse prevention, quality assurance, and product improvement. OpenAI says it has internal controls limiting access, but the access is real.

OpenAI’s AI systems: Whether your conversations are used for model training depends on your opt-out settings, but they’re still processed by OpenAI’s systems regardless.

Law enforcement and government agencies: Under a valid legal order, a subpoena, court order, or national security letter, OpenAI can be required to produce user data. OpenAI publishes a transparency report detailing these requests. Whether it notifies you depends on whether the order includes a gag provision.

Third-party plugins and integrations: If you use ChatGPT plugins or connect it to third-party services, those third parties receive the conversation context they need. Their data handling is governed by their own privacy policies, not OpenAI’s.

Shared conversations: ChatGPT lets you generate a shareable link for any conversation. Anyone with the link can read it. This is opt-in and requires your action.

What happens when you delete a conversation?

Deleting a conversation removes it from your account view immediately. It is then permanently deleted from OpenAI’s systems within 30 days, unless a legal obligation requires longer retention. Deletion does not retroactively remove conversation content already incorporated into model training runs

When you hit “Delete” on a ChatGPT conversation:

Immediately: The conversation disappears from your account interface.

Within 30 days: OpenAI deletes the conversation from its internal systems and backups.

Legal exceptions: If OpenAI is legally required to preserve specific data, the 30-day window can be extended. OpenAI doesn’t notify you of these exceptions in real time.

Training data: If your conversation was already incorporated into a model training run before you deleted it, that deletion doesn’t remove its influence on the model. The model has already been updated based on that data.

Account deletion: Deleting your entire OpenAI account triggers a similar 30-day retention window for all your data.

The practical implication: deletion is meaningful and removes most active access. It’s not the same as the conversation never having existed, especially if it was already used for training.

The difference between free, Plus, Team, and Enterprise

Privacy protections increase as you move up the plan tiers. Free and Plus users are subject to model training use by default (opt-out available). Team users have training opt-out on by default. Enterprise users have conversations excluded from model training and can configure stricter data retention. API operators control retention via their service agreement.

Free plan

Conversations stored indefinitely

May be used for model training (opt-out available)

No zero-retention option

ChatGPT Plus ($20/month):

Same storage defaults as free

Same training opt-out availability

Access to Temporary Chat mode

ChatGPT Team:

Model training opt-out enabled by default

Workspace admins can manage data retention settings

Not automatically zero-retention

ChatGPT Enterprise:

Conversations excluded from model training by default

Configurable data retention policies (can be set to zero additional retention after processing)

Encrypted at rest and in transit

Admin console with detailed data controls

API:

No storage of conversations for training by default (as of March 2023 OpenAI policy update)

Retention controlled by operator service agreements

If you or your organization handles genuinely sensitive information, Enterprise or the API with appropriate configuration is the right tier, not Plus.

Temporary Chat, what it does and doesn’t do

Temporary Chat mode prevents conversations from being saved to your account history and excludes them from model training. OpenAI still processes the conversation on its servers in real time, and retains it for up to 30 days for safety/abuse monitoring. It’s ChatGPT’s most private standard mode, but it’s not the same as the conversation never existing.

Temporary Chat is available via a toggle at the top of the interface. When enabled

What it does:

Conversation is not saved to your history

Not used for model training

Deleted from OpenAI’s systems within 30 days

What it does not do:

Does not prevent real-time processing on OpenAI’s servers

Does not prevent OpenAI from reviewing the conversation for safety/abuse during the 30-day window

Does not prevent OpenAI from complying with a legal order during that window

Does not prevent session metadata (IP address, timestamps) from being collected

Using ChatGPT without an account: OpenAI offers limited use without logging in. Conversations aren’t associated with an account, and retention behavior is shorter, but real-time server processing and some metadata collection still occur.

The honest summary: Temporary Chat is a genuine privacy improvement. It’s not a guarantee that the conversation leaves no trace on OpenAI’s infrastructure.

What ChatGPT knows about you beyond your messages

Beyond your conversation content, OpenAI collects your IP address (which can be linked to your identity via your ISP), device and browser fingerprint, geographic location derived from IP, usage patterns, and account information. If you use ChatGPT while logged into a Google or Microsoft account (via SSO), those providers also know you’re using the service.

IP address: Your real IP address is sent to OpenAI’s servers every time you connect. It reveals your approximate location and can be used by your ISP to link your sessions to your real-world identity.

Device and browser fingerprint: Browser type, operating system, screen resolution, language settings, and other technical attributes are collected. Combined with an IP address, these create a fairly specific identifier for your device.

Geographic location: Derived from your IP address, typically to the city or neighborhood level.

Usage patterns: When you log in, how often you use it, how long sessions last, which features you use.

Cookies and tracking technologies: OpenAI uses cookies on the ChatGPT web interface, which can persist across sessions and link your behavior over time.

Single sign-on (SSO): If you log into ChatGPT using “Continue with Google” or “Continue with Microsoft,” those platforms know you’re using ChatGPT and your account is linked to your identity there.

Can OpenAI be compelled to hand over your data?

Yes. OpenAI is a US company and must comply with valid US legal process, subpoenas, court orders, and national security letters. It publishes a transparency report. Whether it notifies you of a legal demand depends on whether the order includes a non-disclosure provision. Conversations stored on its servers are legally accessible to US authorities under appropriate legal process.

OpenAI is incorporated in the United States. US law enforcement and intelligence agencies can compel OpenAI to produce user data under various legal instruments, including subpoenas, court orders under the Electronic Communications Privacy Act (ECPA), and national security orders.

What a subpoena or court order can produce:

Your account information (name, email, payment details)

Your IP address and connection metadata

The content of your stored conversations

Gag orders: National security orders can include non-disclosure provisions preventing OpenAI from notifying you that your data was requested. This applies to all US internet companies, not just OpenAI.

Practical relevance: For most users, the risk of a government legal demand for their ChatGPT conversations is near zero. The risk is concentrated among specific categories: subjects of criminal investigations, journalists communicating about sensitive matters, activists in politically sensitive contexts, and people in industries with regulatory scrutiny.

If you fall into any of these categories, Temporary Chat mode, an Enterprise or API configuration, or simply not inputting sensitive information into ChatGPT is the practical protective measure.

What you should never type into ChatGPT

Given that conversations may be reviewed, retained, and legally accessible, avoid typing: full names combined with sensitive personal details, confidential client or patient information, passwords or access credentials, sensitive financial or medical specifics, and anything you wouldn’t want OpenAI’s staff or a US court to read.

ChatGPT is a powerful tool. It’s not a private journal, a confidential lawyer-client conversation, or a HIPAA-protected medical record. Here’s what to keep out:

Your full name + sensitive personal details in combination: Typing “My name is [Name] and I have [medical condition]” creates a record linking your identity to sensitive health information. It’s legally accessible even if OpenAI never misuses it.

Client, patient, or employee information: If you work in law, medicine, finance, or HR and paste client details into ChatGPT, those details are now on OpenAI’s servers and may violate professional confidentiality obligations.

Passwords, API keys, or access credentials: Treat it like pasting credentials into a public Slack channel.

Anything covered by an NDA: NDA-protected information leaves your control the moment you hit Enter. Assess the risk consciously rather than assuming it away.

Anything you’d be uncomfortable seeing in a court document: Whatever you type is accessible to OpenAI’s staff, potentially to US law enforcement with appropriate legal process, and potentially to opposing parties in litigation involving OpenAI.

How to reduce your ChatGPT data footprint, practical steps

The most effective steps are: turn off chat history and training in account settings, use Temporary Chat for sensitive sessions, use the API with zero-retention configuration for work involving sensitive information, use a VPN to mask your IP address from OpenAI’s servers, and avoid typing personally identifying details alongside sensitive information.

Step 1, Turn off model training (free and immediate): Settings → Data Controls → toggle off “Improve the model for everyone.” This stops your conversations from being used for model training, but it does not reduce storage or prevent safety review.

Step 2, Use Temporary Chat for sensitive sessions: Toggle Temporary Chat before any session involving sensitive topics. Conversations aren’t saved to your history, excluded from training, and removed from OpenAI’s systems within 30 days.

Step 3, Use a VPN when accessing ChatGPT: A VPN masks your IP address from OpenAI’s servers. Instead of your real IP, OpenAI sees the VPN server’s IP. This breaks the IP-to-identity link in OpenAI’s session metadata. More on this below.

Step 4, Delete conversations regularly: Delete conversations containing sensitive content as soon as you’re done. The 30-day retention clock starts from deletion.

Step 5, Don’t use SSO from Google or Microsoft: Create a standalone OpenAI account with an email address rather than linking it to your Google or Microsoft identity.

Step 6, For sensitive work, use the API with retention controls: If you need AI assistance for genuinely sensitive work, legal documents, medical records, financial analysis, the API with a zero-retention configuration is the correct tool, not the consumer ChatGPT interface.

Step 7, Delete your account if you stop using the service: Actively delete rather than just stopping logins. This triggers the 30-day retention clock for all your stored data.

Where a VPN fits into AI privacy

A VPN masks your IP address from ChatGPT’s servers and prevents your ISP from seeing that you’re connecting to OpenAI. It does not encrypt or hide the conversation content itself, ChatGPT needs to see your prompts to respond. A VPN mainly helps by removing the IP-to-identity link from OpenAI’s session metadata, which is a meaningful privacy improvement even though it doesn’t directly address the conversation content.

What a VPN genuinely helps with:

IP address masking from OpenAI: OpenAI’s servers see the VPN server’s IP, not your real one. Your real IP, which your ISP can use to identify you, isn’t recorded in OpenAI’s session metadata.

ISP visibility: Without a VPN, your ISP can see that you’re connecting to OpenAI’s servers, a record that, in the US, can be sold to data brokers or compelled by law enforcement. A VPN prevents your ISP from seeing that you’re using ChatGPT at all.

Public WiFi eavesdropping: A VPN encrypts the connection between your device and the VPN server, preventing anyone else on a public network from intercepting your traffic.

What a VPN does not help with:

Conversation content: ChatGPT needs to receive your prompts to generate responses. A VPN can’t hide your words from the service you’re using.

Account-based identity: If you’re logged into a ChatGPT account, OpenAI knows you’re the account holder regardless of what IP you’re connecting from.

Conversation storage: A VPN has no effect on whether OpenAI stores your conversations after receiving them.

The practical combination: The most effective approach combines Temporary Chat mode, training opt-out, and a VPN. Together, these meaningfully reduce your data footprint compared to default settings, without making the conversation completely private.

Common myths about ChatGPT privacy

Myth 1: “ChatGPT conversations are private between me and the AI.”

ChatGPT is not a private messenger. Conversations are processed on OpenAI’s servers, may be reviewed by staff, may be used for model training, and are legally accessible to US law enforcement under appropriate legal process.

Myth 2: “Turning off chat history means OpenAI can’t see my conversations.”

Disabling chat history prevents conversations from being saved to your account. OpenAI still processes them on its servers in real time and retains them for up to 30 days for safety monitoring. “Not in your history” is not the same as “not on OpenAI’s servers.”

Myth 3: “Deleting a conversation removes it from OpenAI’s systems immediately.”

Deletion removes the conversation from your view. It remains on OpenAI’s infrastructure for up to 30 days. If it was already used for model training before deletion, that influence on the model remains.

Myth 4: “OpenAI can’t be legally compelled to produce my conversations.”

OpenAI is a US company. US law enforcement and intelligence agencies can compel it to produce user data under appropriate legal process, just as they can compel Google or Microsoft.

Myth 5: “Using a VPN means OpenAI can’t track me.”

A VPN masks your IP address from OpenAI, a real improvement. It does not prevent OpenAI from seeing your conversation content, and it does not prevent account-based identification if you’re logged in. A VPN is one layer of a privacy approach, not a complete solution.

How OllaVPN protects your network layer when using AI tools

When you use ChatGPT, your network connection carries two types of identifiable information: the content of your requests, and metadata about your connection (primarily your IP address and session timing). A VPN addresses the metadata layer. OllaVPN is built to handle it thoroughly.

What OllaVPN does for your ChatGPT sessions:

Masks your IP address from OpenAI’s servers. Every connection appears to come from OllaVPN’s infrastructure, not your home or mobile IP. Your ISP has no record of you connecting to OpenAI.

Prevents your ISP from logging your AI tool usage. Without a VPN, your ISP sees every domain you connect to, including api.openai.com. With OllaVPN, your ISP sees only that you’re connected to a VPN server.

Encrypted tunnel on public networks. OllaVPN encrypts the tunnel between your device and the VPN server, preventing anyone else on a public network from intercepting the connection.

Zero-logs architecture. OllaVPN does not record connection timestamps, session durations, your real IP address, or DNS queries. There’s nothing to produce, not because we won’t share it, but because we don’t have it.

DNS inside the encrypted tunnel. Your DNS queries go through OllaVPN’s own resolver, inside the tunnel. Your ISP can’t see which services you’re connecting to.

No account required on the free plan. No email address needed to get started.

Post-quantum encryption on every connection. The hybrid X25519 + ML-KEM-768 handshake protects your VPN traffic against future quantum decryption.

What OllaVPN doesn’t do:

It cannot hide your conversation content from OpenAI. It cannot prevent OpenAI from using your conversations under its retention and training policies. It cannot make you anonymous to OpenAI if you’re logged into a ChatGPT account. A VPN is the network layer; the content and account layers require the ChatGPT-specific steps described in the reduce footprint section (#reduce-footprint).

OllaVPN plans:

Lifetime free · $0 · 10 Mbps Zero-logs. In-tunnel DNS. Kill switch always on. PQC-ready. No account required. No data caps. Every country.

Paid plan · $2 / month · 10 Gbps Same privacy architecture. Faster. Five devices.
