Zeyt uses a small set of cookies so a session stays with the right person. These cookies are required for the service to work.
After a team member signs in, a session cookie keeps that sign-in so the workspace does not ask again on every page.
When a guest verifies an email on a brand site, an HttpOnly cookie keeps that guest session on that site. Ordering without identifying does not create one.
These cookies are not an advertising profile. They exist to keep the workspace and, when a guest asks for it, the guest session.
