Cookie Policy
Our sites use the cookies they need to sign you in and keep bots out. Google Analytics is the only optional one, and it does not load until you allow it. Global Privacy Control keeps it off without asking.
Table of Contents
1. What This Covers
This policy covers sentinelgrid.us and the SentinelGrid services at its subdomains: the Client Portal, Help Desk, Billing portal, status pages and onboarding form. It explains each cookie and each piece of browser storage we use. How we handle personal data more broadly is in the Privacy Policy.
2. Strictly Necessary
These make the services work, so they cannot be switched off. They are never used for advertising or to follow you across other sites.
- Sign-in session cookies on portal.sentinelgrid.us, support.sentinelgrid.us, billing.sentinelgrid.us and our internal tools. Signed, HttpOnly and Secure. They last for your session or until you sign out, and are cleared when an account is disabled.
- Form and sign-in security: a short-lived token that protects a form from being submitted by another site (CSRF), set only while you are using that form.
- Cloudflare security cookies such as
__cf_bmandcf_clearance, which Cloudflare may set to tell people from bots. They last up to 30 minutes for__cf_bmand as set by the challenge forcf_clearance. - Cloudflare Turnstile, the bot check on our public forms, which reads browser signals when you submit a form. See Cloudflare's Turnstile privacy addendum.
3. Preferences in Your Browser
The website keeps a few settings in your browser's own storage (localStorage and sessionStorage), not in cookies. They stay on your device and are never sent to us.
sg-theme: light, dark or follow your device.sg-motion: the animation setting in the footer.sg-gpu,sg-perf: whether to draw the background in a lighter mode on slower computers, for this visit only.sg-consent: your answer to the analytics question, so we do not ask on every page.
4. Analytics (Optional)
With your permission we use Google Analytics 4 on sentinelgrid.us to see which pages are useful. It sets first-party cookies named _ga and _ga_<id>, which last up to two years, and sends Google the page you viewed, your approximate location, your device and browser, the page that sent you, and a pseudonymous identifier. We use it to understand the site, not for advertising.
None of this loads until you choose Allow analytics. If you choose No thanks, or never answer, Google Analytics does not run. We do not run advertising pixels from Meta, LinkedIn or anyone else.
5. Third-Party Requests Without Cookies
- Google Fonts: your browser downloads our typefaces from Google, so Google sees your IP address. Google Fonts sets no cookies.
- The chat bubble loads from support.sentinelgrid.us, our own help desk. It sets no cookies. What you type is described in the Privacy Policy.
- The email security grader looks up public DNS records through Cloudflare and Google public DNS from your browser. It sets no cookies.
6. Your Choices
You can change your analytics answer at any time. Choosing No thanks after a yes removes the Google Analytics cookies from this site.
The same switch is in the footer of every page as Cookie settings. If your browser sends Global Privacy Control, we treat it as a no on every page and never ask. You can also block or delete cookies in your browser settings; the strictly necessary ones are needed to sign in.
7. Changes
If we add a cookie or a tag, we update this page and the date at the top before it goes live. A new optional tag will not load until you are asked again.
