Cookies and browser storage
Cairn is a tool for managing your own devices and tickets. It carries no advertising, no analytics, and no third-party scripts, so there is nothing here that follows you anywhere else.
Cookies
| Name | Purpose | Lasts |
|---|---|---|
portal_session |
Keeps you signed in. It holds a random value, not your identity — the account it belongs to is looked up on our side each time. | Until it expires or you sign out |
__Host-portal_sso |
Set only when you sign in with Microsoft or Google, so that the sign-in can be finished only in the browser that started it. It holds a random value. | 10 minutes, or until the sign-in finishes |
__Host-portal_consent |
Set only when somebody starts connecting Microsoft 365, so that the connection is finished for the sign-in that started it. It holds a random value. | 15 minutes, or until the connection finishes |
Each is marked HttpOnly so no script can read it,
Secure so it is only ever sent over HTTPS, and
SameSite=Lax so another site cannot use it to act as you. Signing
out deletes the session cookie here and ends the session on our side, so a copy of it is no
longer good for anything.
Kept in your browser, not sent to us
| Name | Purpose |
|---|---|
portal-theme |
Your light or dark choice, saved only if you pick one. Left alone, the portal follows whatever your device already asks for. |
portal-cookie-notice |
That you have read the notice at the bottom of the page, so it stops appearing. Kept here rather than in a cookie, so that reading a notice about cookies does not set one. |
Why there is no “accept” button
Consent rules cover cookies that are not needed to provide the thing you asked for — advertising, analytics, tracking between sites. A cookie that keeps you signed in is not one of those: refuse it and Cairn cannot work at all. Offering a choice that is not a real choice would be theater, so you get told plainly instead.
Clearing them
Signing out removes the session cookie. Clearing site data for this address in your browser removes everything above; Cairn will then ask you to sign in again and follow your device's light or dark setting until you choose otherwise.
The rest
How RVA Tech Visions handles your information more broadly is in the privacy policy, and the terms and conditions cover the service itself.
