Cookie Policy
This policy lists the cookies and similar technologies brillnexsystems.com uses, what each one is for, how long it lasts, and how to turn the optional ones off.

1. What cookies are
Cookies are small text files a website stores on your device. They let a site remember your actions and preferences, and let us measure how the site is used. This policy also covers similar technologies (local storage, pixels and browser-side scripts) that do the same job by different means.
2. Cookies this site uses
| Set by | Type | Purpose | Typical lifetime |
|---|---|---|---|
| Brillnex Systems | Strictly necessary | Remembers your cookie choice (brillnex_consent), so we do not ask again on every page. It does not identify you. | 12 months |
| Brillnex Systems | Strictly necessary | Remembers whether your region requires us to ask (brillnex_geo), so we do not check again on every page. It does not identify you. | 24 hours |
| Google Analytics | Analytics | Measures pageviews, sessions, traffic sources, and approximate location so we can see which pages are useful (_ga and _ga_<ID>). | Up to 2 years |
| Vercel Analytics | Analytics | Privacy-focused traffic measurement for page performance and visit counts. Does not use cross-site identifiers. | No cookies (cookieless measurement) |
| Apollo.io | Analytics / business identification | Identifies the organisation associated with a visitor’s IP address. In the United States it may also match professional contact details. | Up to 24 months |
| Congreeto | Functional | Runs the chat widget and remembers your conversation so it persists between pages. Uses browser session storage (__congreeto_attr_v1, __congreeto_sess_v1_<token>, __congreeto_pos_v1_<token>), not cookies. | Cleared when the tab closes |
We do not use advertising cookies, and we do not sell data collected through cookies.
3. Strictly necessary vs optional
Strictly necessary cookies are required for the site to function and cannot be switched off through a consent control. Everything else (analytics and business identification) is optional. The chat widget loads for all visitors because it is part of how we answer enquiries; it stores only the session data needed to run the chat. Blocking the optional ones does not stop you reading any page on this site or contacting us by email or phone.
If you are visiting from the United Kingdom, the EEA or Switzerland, we ask before any analytics or visitor-identification cookie is set. Choose Decline and Google Analytics and Apollo never load at all. Everything on the site stays available to you: every page, the contact form, and the chat widget.
Outside those regions we load analytics without asking, as permitted by local law. You can still block them in your browser at any time using the controls in the next section.
4. How to control cookies
You can control or delete cookies at any time:
- Change your mind at any time using Cookie settings in the footer.
- Browser settings: every major browser lets you block or delete cookies, and most offer a "block third-party cookies" option. Check the privacy or security section of your browser’s settings.
- Google Analytics opt-out: Google publishes a browser add-on that prevents Analytics from collecting your data on any site.
- We do not currently respond to Do Not Track signals; use the cookie controls above instead.
- Blocking scripts: a reputable content blocker will stop the analytics and visitor-identification scripts loading at all.
Blocking strictly necessary cookies may cause parts of the site to behave unexpectedly.
5. Changes to this policy
We review this policy whenever we add or remove a tool that sets cookies. The "last updated" date above always reflects the current version.
