Cookie Policy

There is no earlier text to compare against — this is the first full capture of OpenAI's Cookie Policy, so every line shows up as "added" rather than as a real change to your rights. The policy itself lists the cookies OpenAI sets, including a large set of advertising and marketing trackers from Meta, Google, TikTok, Reddit, LinkedIn and Bing, plus cookies tied to an ads.openai.com domain and "personalized marketing" consent. Nothing here shows terms getting worse than before; the notes below describe what the policy says today so you know what you're agreeing to.

Ad and social companies get tracking cookies on OpenAI sitesMeta, Google, TikTok, Reddit, LinkedIn, and Bing all set cookies on openai.com,…

Meta, Google, TikTok, Reddit, LinkedIn, and Bing all set cookies on openai.com, chatgpt.com, and ads.openai.com. These identifiers let those companies tie your visits to OpenAI back to the profiles they already keep on you, and they can be used to target ads elsewhere. This is disclosure of current practice, not a newly added right — but it is the biggest privacy item in the document.

“| [Meta](https://www.facebook.com/privacy/policies/cookies/) | datr | 400 days | Marketing measurement | openai.com”

What you can do — Open cookie settings on openai.com and chatgpt.com and turn off marketing cookies, then repeat on every browser and device you use.

DATA SHARING

There are dedicated consent cookies for "personalized marketing" and several cookies scoped to an ads.openai.com domain. That means your activity can be used to tailor which ads you see, not just to count how ads perform.

“| [OpenAI](https://openai.com/policies/privacy-policy/) | personalized\_marketing\_consent | 6 months | Personalized marketing consent\* | openai.com”

What you can do — Decline personalized marketing in the cookie banner or settings; the choice is stored for 6 months, so re-check it twice a year.

DATA COLLECTION
Some tracking identifiers last over a yearSeveral trackers stick around for a very long time — Meta's datr and sb for 400 days,…

Several trackers stick around for a very long time — Meta's datr and sb for 400 days, Google's IDE and Meta's API for 24 months, and multiple OpenAI cookies for 1 to 2 years. A device identifier that lives that long can link activity across many separate visits.

“| [Google](https://policies.google.com/technologies/partner-sites) | IDE | 24 months | Marketing measurement | openai.com”

What you can do — Clear your browser cookies periodically, or use a browser setting that deletes third-party cookies automatically.

DATA RETENTION
Cookie controls are not available everywhereThe policy only promises cookie choices where the law requires them. If you live somewhere…

The policy only promises cookie choices where the law requires them. If you live somewhere without strong cookie rules, you may not be offered the option to turn marketing cookies off at all.

“If you are in a jurisdiction that allows for that control, you can access your cookie settings directly on our various sites.”

What you can do — If you see no cookie settings on the site, use your browser's own controls to block third-party cookies instead.

1This Cookie Policy describes what kinds of cookies and similar technologies OpenAI uses in connection with our Services (as defined in our [Privacy Policy](https://openai.com/policies/privacy-policy/)), and how you can manage them. This Cookie Policy does not address how we process your personal information outside of our usage of cookies. To learn more about how we process your personal information, please read our [Privacy Policy](https://openai.com/policies/privacy-policy/).
+ ADDEDFirst full capture of the Cookie Policy

The prior snapshot was empty, so the whole document appears as new. Nothing in this diff proves OpenAI changed its cookie practices — it just means this is the starting point for tracking future changes.

3## Types of cookies
4
5Cookies are small text files that may be placed on your device when you interact with online services. They can help websites remember details about your visit, such as your preferred language or when you logged in, which can enhance your experience on subsequent visits. Cookies can also be used for other purposes, such as troubleshooting errors, better understanding service usage, and supporting marketing efforts. Cookies set directly by us are called first-party cookies. We also use third-party cookies, which originate from a domain different from the one you are currently visiting. Similar technologies, such as pixels, web beacons, sharing of device IDs and other identifiers via APIs or local storage, can also be used for these purposes. For simplicity, we also refer to these technologies as "cookies" in this Cookie Policy.
+ ADDED"Cookies" covers more than cookies

The policy says that pixels, web beacons, device IDs shared through APIs, and browser local storage are all lumped in under the word "cookies." That means some tracking happens through methods your browser's cookie controls may not touch.
