This Cookie Policy describes what kinds of cookies and similar technologies OpenAI uses in connection with our Services (as defined in our 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.

Types of cookies

Cookies 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.

Necessary cookies

These cookies are required to operate our Services. For example, they allow us to authenticate users or enable specific features within the Services, including for security purposes.
