This notice explains the cookies and similar technologies used by supervisionvms.com. We keep this deliberately minimal: one strictly necessary cookie for our own staff, plus optional analytics cookies that are set only if you accept them. We use no advertising or cross-site tracking cookies.
1. Cookies we use
| Cookie | Purpose | Type | Lifetime |
|---|---|---|---|
sv_admin |
Set only for our own staff after they sign in to the site's admin area. It is a signed session token, scoped to the admin pages, and is never set for ordinary visitors. | Strictly necessary | Session (short-lived) |
_ga, _ga_<id> |
Set by Google Analytics 4 to distinguish visitors and remember session state so we can measure how the site is used (pages viewed, sign-ups, downloads). Set only after you accept analytics. Contains a randomly generated client identifier — no name, email, or precise location. | Analytics (optional, consent-based) | Up to 2 years |
The sv_admin cookie is set with the HttpOnly, Secure, and SameSite=Lax attributes. HttpOnly means client side scripts cannot read them, Secure means they are only sent over HTTPS, and SameSite=Lax limits it to first party navigation. Its value is signed with HMAC so they cannot be tampered with.
We also store a small flag in your browser's localStorage (sv_consent) to remember your analytics choice. It is not a cookie and is never sent to a server. The download links we email set no cookie at all.
2. Your analytics choice
The first time you visit, we show a consent banner asking whether we may use Google Analytics. No analytics cookies are set and no analytics scripts load until you click "Accept." If you click "Decline," nothing is loaded. Your choice is remembered in your browser (sv_consent) so you are only asked once; clear your browser storage for this site to be asked again. The strictly necessary cookie above does not require consent because it is only set for our own staff when they sign in.
3. Analytics
When you accept, we use Google Analytics 4 (GA4), provided by Google, to understand aggregate usage — which pages are visited, and how many people sign up or download. GA4 is configured with IP anonymization and without Google advertising features, and we do not use it for cross-site tracking. You can withdraw consent at any time by clearing this site's cookies/storage in your browser, and you can learn more about Google's data practices at policies.google.com/privacy. This is described further in our Privacy Policy.
4. Managing cookies
You can delete or block cookies through your browser settings. The site, the contact form and the emailed download links all work without cookies.
5. Changes
We may update this notice from time to time and will revise the effective date above.
