Only the cookies ROOF needs.
ROOF currently uses essential cookies for sign-in, security and private-site access. It does not use advertising or analytics cookies.

- roof_access keeps a signed-in session active for a limited period.
- roof_refresh securely renews an eligible session for up to 30 days.
These cookies are HttpOnly, Secure and SameSite=Lax, which means page scripts cannot read them and browsers limit when they are sent.
Hosting access
Because the beta is hosted as a private ChatGPT Site, the hosting service may use strictly necessary cookies to verify that a visitor is permitted to open it and to protect the service.
No tracking cookies
ROOF has no advertising pixels, behavioural tracking, analytics service, social embed or cross-site marketing cookie. A cookie banner is therefore not shown: rejecting the essential cookies would prevent secure sign-in or private-site access. If optional analytics or marketing technology is introduced, it will remain off until the visitor makes a clear choice.
Browser controls
You can remove or block cookies through browser settings. Blocking essential cookies will sign you out or prevent the private beta from opening.
