Cookie Policy

Last updated: 14 November 2026. This page explains what cookies are, which cookies OpenChatGPT uses, and how you can control them.

What are cookies?

A cookie is a small text file that a website asks your browser to store on your device. When you visit the site again, the browser sends the cookie back, and the site remembers something about your last visit — for example, a setting you chose or a login. Cookies are a normal part of how the web works: they remember preferences, keep shopping carts, and help advertisers measure which ads were shown. Your browser controls them: you can block them, delete them, or set your browser to ask you each time a site wants to store one. This site also uses localStorage, which is a similar browser storage feature — your chat history is kept there, in your own browser, and it works the same way: it stays on your device and you can delete it at any time.

Which cookies does this site use?

Consent choice. When you answer the cookie banner at the bottom of the page — Accept or Dismiss — your choice is saved in your browser's localStorage so the banner does not appear on every page. If your browser blocks localStorage (for example, in private browsing mode), the choice is saved instead as a small cookie called ocg_consent_v1, which lasts for one year.

Advertising cookies (Google AdSense). This site shows ads through Google AdSense. Google and its advertising partners may set cookies on your device to show ads, to measure how often an ad was shown, and — if you have not opted out — to show ads based on your visits to this and other websites. These are third-party cookies: they are set by Google, not by OpenChatGPT, and they are governed by Google's own privacy policy, not by ours. The chat itself does not set any tracking cookies, and the site does not use cookies to build a profile of you or to sell your data.

No other cookies. The site does not set analytics cookies, social media cookies, or login cookies, because there is no account, no login, and no analytics tracking of its own. The chat page loads a markdown-rendering library from a public CDN (jsDelivr); that is a file download, not a cookie, although the CDN may see your IP address when the file is fetched, as with any website resource.

How to opt out of personalised ads

You can turn off personalised advertising from Google at any time. Visit google.com/settings/ads while signed in to your Google account and switch off ad personalisation — Google will then show you ads that are not based on your browsing. You can also opt out of personalised advertising from many providers at once through the Network Advertising Initiative at optout.networkadvertising.org. Opting out does not remove ads from this site: you will still see ads, but they will not be chosen based on your interests. You can also use the "Cookie settings" link in the footer of any page to re-open the consent banner and change your choice.

How to clear or block cookies

Every modern browser lets you delete cookies and block new ones. In Chrome, go to Settings, then Privacy and security, then "Delete browsing data" for cookies, or "Third-party cookies" to block them. In Firefox, go to Settings, then Privacy and Security, then "Cookies and Site Data". In Safari, go to Settings, then Privacy, then "Manage Website Data". In Edge, go to Settings, then "Cookies and site permissions". Deleting cookies signs you out of websites that use them and removes saved preferences, so you may need to answer the cookie banner again on your next visit. You can also set your browser to block third-party cookies only — that stops advertising cookies while leaving first-party cookies, like the consent choice, working normally.

What happens if you block cookies?

The chat works the same whether you accept or block cookies. Blocking cookies does not stop you from chatting, and it does not delete your chat history, because your chats are stored in localStorage, not in a cookie. If you block all cookies, the consent banner may appear again on your next visit, because the site cannot remember your choice without storing it somewhere. Ads may still appear, but they will be less personalised. Nothing else on the site depends on cookies.

Changes to this policy

If this policy changes in a material way, the "Last updated" date at the top will change and the new version will be posted here. Continued use of the site after a change means you accept the updated policy.
