Cookie Policy

OpenAI's cookie policy table was updated mainly to document cookies for a new sub-domain, chatgpt.site, which looks like it supports a new 'build and host sites/apps' feature. Six new cookies were added there (login, session, visitor tracking, preview/admin tokens), a new analytics cookie was added for that domain, and an existing 2-year tracking identifier (oai-did) was extended to also run on help.openai.com. Several duplicate rows for consent cookies were also cleaned up, and some infrastructure/security cookies were extended to a couple of additional subdomains.

OpenAI added several new cookies tied to a new product area at the chatgpt.site domain, including sign-in and session cookies that can last up to 400 days. These are mostly needed for the feature to work, but it means a new set of identifiers tied to you now exists on a domain you may not have interacted with before.

A new cookie tracks visitor activity on the chatgpt.site domain for up to 90 days. Unlike the necessary cookies, this one is for analytics, so you may be able to turn it off.

“__Host-appgarden-visitor | 90 days | Analytics | .chatgpt.site”

What you can do — Check your cookie preference settings on the site and opt out of analytics cookies if you don't want this tracking.

The 'oai-did' cookie, a 2-year device identifier, is now also placed when you visit help.openai.com, slightly widening the set of pages where this identifier can follow you.

ALSO IN THIS CHANGE, NOT TIED TO ONE LINE

  1. + ADDEDNew cookies for the chatgpt.site domain

    Six new cookies were added tied to a new site/app domain (.chatgpt.site): a 365-day functionality cookie, two sign-in cookies (one lasting 400 days), a 400-day session cookie, and two security tokens for previewing and admin review.

    chatgpt_sites_siwc_session | 400 days | User authentication | .chatgpt.site

  2. + ADDEDNew analytics cookie for chatgpt.site

    A new 90-day analytics cookie, __Host-appgarden-visitor, was added to track visitor behavior on the .chatgpt.site domain.

    __Host-appgarden-visitor | 90 days | Analytics | .chatgpt.site

  3. − REMOVEDRemoved duplicate rows for country, analytics_consent, and marketing_consent

    Three cookie rows that duplicated entries already listed earlier in the table (with a different, shorter duration) were removed. This is a cleanup of the table, not a change to how these cookies work.
