What this notice covers
This notice explains the cookies and similar technologies we use on nuoptima.com. "Similar technologies" matters here, because the rules that apply in the UK cover more than cookies. They cover anything that stores information on your device or reads information already stored there. That includes tracking pixels, tags, scripts, software development kits and browser storage such as local storage and session storage. Everywhere this notice says "cookies", read it as covering all of those. The site is operated by NUOPTIMA Limited, a company registered in England and Wales with company number 14407366, registered office 1 Beauchamp Court, 10 Victors Way, Barnet, Hertfordshire, England, EN5 5TZ. We are the data controller. You can reach us at [email protected].
What cookies are
A cookie is a small text file that a website asks your browser to save. When you come back, the browser hands it over again, so the site can recognise the session, remember a setting, or count the visit. Some cookies are set by us and some are set by other companies whose services run on our pages. Local storage works in a similar way but keeps the data in the browser until it is cleared.
The categories we use
- Strictly necessary. Needed to deliver the site securely and reliably, including protection against attacks and abuse. These do not need your consent because the site cannot work without them.
- Functional. Support features you actively use, such as the chat widget and the booking calendar.
- Analytics. Tell us how many people visit, which pages they read, and where things break.
- Advertising. Measure the results of our campaigns and let us show ads to people who have already visited.
We do not show a cookie banner. What runs depends on where you are. In the UK, the European Economic Area and Switzerland, Google's tags run without cookies (Google Consent Mode set to denied) and the analytics and advertising tools loaded through our tag container do not run; RB2B and Bento load there too, and RB2B identifies visitors outside the United States at company level only. Everywhere else, the tools below run by default. If your browser sends a Global Privacy Control signal, the advertising and visitor identification tools stay off wherever you are. The Browser controls section explains how to block cookies yourself, and blocking them has no effect on your ability to read the site or contact us.
What actually runs on this site
The table below lists every provider we load. Apart from Cloudflare, the chat widget, Bento, the booking calendar and RB2B, all of them are loaded through our Google Tag Manager container (GTM-MK3WWKP) rather than being written into the page code. Where a provider sets its own cookies under names it controls and changes from time to time, we say so rather than publishing a list that would go stale.
| Provider | What it does | Category | Cookies or storage used | Where it runs |
|---|---|---|---|---|
| Google Tag Manager | Loads and manages the tags listed below. It does not track you by itself. | Tag container | None of its own | Everywhere |
| Google Analytics 4 | Measures audience and traffic: visits, pages viewed, how people arrive. | Analytics | _ga, _ga_KPM79C7M8J |
Everywhere; without cookies in the UK, EEA and Switzerland |
| Google Ads | Conversion measurement and remarketing for our paid search campaigns. | Advertising | _gcl_au |
Everywhere; without cookies in the UK, EEA and Switzerland, and without advertising cookies where a Global Privacy Control signal is sent |
| Meta Pixel | Advertising and remarketing across Facebook and Instagram. | Advertising | _fbp |
Outside the UK, EEA and Switzerland, and not where a Global Privacy Control signal is sent |
| LinkedIn Insight Tag | Advertising and conversion tracking for our LinkedIn campaigns. | Advertising | LinkedIn sets its own | Outside the UK, EEA and Switzerland, and not where a Global Privacy Control signal is sent |
| Microsoft Clarity | Session recording and heatmaps. See the section below. | Analytics and behavioural | Microsoft sets its own | Outside the UK, EEA and Switzerland |
| RB2B (Retention.com) | Visitor identification. Works out who is visiting our site by matching the visit against contact data its partners hold. See the section below. | Advertising and identification | RB2B sets its own | Everywhere, except where a Global Privacy Control signal is sent; you can opt out with RB2B directly (see below) |
| Ahrefs Analytics | Traffic analytics alongside our search performance reporting. | Analytics | Ahrefs sets its own | Outside the UK, EEA and Switzerland |
| Chatwoot | Runs the chat widget, which appears about ten seconds after a page loads. | Functional | Chatwoot sets its own | Everywhere |
| Bento | Our email marketing platform. Its script records page views against a visitor identifier, and against your email address once you have given it to us, so we can see which pages a known contact has read. | Analytics and advertising | Bento sets its own | Everywhere |
| GoHighLevel / LeadConnector | Runs the booking calendar. It loads when you open the booking page or click a booking button: that is a service you are explicitly requesting, so the embed itself is strictly necessary to provide it. | Functional | userID, firstPage |
When you book a call |
| Cloudflare | Hosting, security and performance monitoring, including bot and attack protection and the invisible Turnstile check on our forms (see the Turnstile Privacy Addendum). | Strictly necessary | Cloudflare sets its own | Everywhere |
| NUOPTIMA (this site) | Stores a two-letter country code for 24 hours so the site knows which of the rules above apply to your visit. It does not identify you. | Strictly necessary | nu_geo |
Everywhere |
Durations we measured on this site on 1 August 2026: _ga and _ga_KPM79C7M8J last about 400 days, _gcl_au and _fbp about 90 days, and userID and firstPage about one day; Chatwoot's and Bento's cookies are governed by those providers. The providers set these durations and can change them, and the cookies set directly by LinkedIn, Microsoft, Ahrefs and Cloudflare are governed by those providers. Treat the figures above as current rather than fixed.
Microsoft Clarity
Clarity deserves a separate mention because it does more than count visits. It records how people move through and interact with our pages: scrolling, mouse movement, clicks and taps, and the order in which pages are viewed. Those recordings are played back without name or contact details attached and combined into heatmaps. We use them to find pages that confuse people, buttons that do not get seen, and layouts that fail on smaller screens. We configure Clarity to mask input fields, so text you type into forms is not captured in the recording. Clarity does not run for visitors in the UK, EEA or Switzerland, and Microsoft processes the data under its own terms as well as ours.
RB2B
RB2B, run by Retention.com, Inc, identifies business visitors to our site. When you visit, cookies and similar technologies may be used by RB2B and its data partners to associate your visit with other personal information they already hold about you, including your name, business email address and the company you work for, and RB2B then tells us who visited and which pages were viewed. RB2B provides person level details only for visitors it identifies as being in the United States. If RB2B identifies visitors outside the United States, that identification is company level only. We use it to understand who is researching our services, and we may follow up by email. RB2B runs by default wherever you are, unless your browser sends a Global Privacy Control signal, in which case it does not load. You can also opt out with RB2B directly at app.retention.com/optout. If you are outside the United States, RB2B also offers an international opt-out at rb2b.com/rb2b-gdpr-opt-out.
Your choices
We do not ask for consent through a banner. The site applies the rules above by region, honours the Global Privacy Control signal, and leaves the rest to controls you hold yourself: your browser settings, described in the next section, and the opt-outs the providers offer, such as RB2B's opt-out pages above. If you block cookies or send a Global Privacy Control signal, the site still works. You can read every page, use the contact form and reach us by email.
Browser controls
Your browser can block cookies, delete them, or clear them automatically when you close it. Most browsers also offer a private browsing mode that discards them at the end of the session. These controls sit with you and work independently of anything on our site. Blocking all cookies can break parts of some websites, including features on ours such as the chat widget. The settings live in your browser's own preferences under privacy or site data.
Third-party cookies
Several of the cookies described above are set by the providers in the table, not by us. Those companies act as independent controllers for their own purposes, which can include measuring their advertising networks and improving their own products. We do not control what they do with data collected in that capacity, and we cannot delete it on your behalf. If you want to know how a particular provider handles your data, how long it keeps it, or how to object, check that company's own privacy and cookie policies and the account or ad settings it offers.
Changes to this notice
We update this notice when the technologies on the site change, so it stays an accurate description of what actually runs. Material changes to the categories or providers will be reflected here. If you have a question about anything on this page, or want to ask about the data we hold, email [email protected].
