Cookie Policy
Effective date: 23 March 2026
Official policy. This document is the current published version, in force from the effective date shown above. It is issued by MCILVEEN FUELS LTD, trading as MCESMR, and applies to your use of mcesmr.com and purchases made through it. Questions about this document can be sent to contact@mcesmr.com.
This Cookie Policy explains how MCESMR (mcesmr.com) uses cookies and similar technologies, the categories we use, the legal basis for each, and how you can manage or withdraw your consent at any time.
About this policy
This Cookie Policy applies to the website at mcesmr.com (the "Site"), operated by MCILVEEN FUELS LTD, a company registered in Northern Ireland under company number NI617829, with its registered office at 17 Dunesmullan Road, Markethill, Co Armagh, BT60 1TJ, United Kingdom, trading as MCESMR ("we", "us", "our").
It explains what cookies and similar technologies are, which ones we use, why we use them, how long they last, and the choices you have. It should be read together with our Privacy Policy, which sets out in more detail how we handle your personal data under the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018.
Our use of cookies is governed by the Privacy and Electronic Communications (EC Directive) Regulations 2003 ("PECR") and, where cookies process personal data, by the UK GDPR. Under PECR we may store and access cookies on your device only where they are strictly necessary to provide a service you have requested, or where you have given your consent.
Where we are registered with the Information Commissioner's Office (ICO), our registration reference is: to be confirmed.
What are cookies and similar technologies?
A cookie is a small text file that a website places on your device (computer, tablet or phone) when you visit. Cookies let the Site recognise your device, remember information about your visit, keep your shopping basket and session working, and help the Site run securely and reliably.
"Similar technologies" means other methods that store or read information on your device or track activity in comparable ways. Where we (or our providers) use any of these, we treat them under this policy in the same way as cookies. They include:
- Local storage and session storage — browser storage used to hold small amounts of data (for example, your cookie preferences or temporary checkout state) on your device.
- Pixels, tags and web beacons — tiny files or snippets of code, sometimes embedded in pages or emails, used to record that content has loaded or to support analytics and fraud prevention.
- Software development kits (SDKs) and scripts — code loaded from us or a third-party provider (such as our payments or analytics provider) that may set or read cookies or identifiers.
- Device or session identifiers — values used to distinguish one session or device from another, for example to keep you logged in or to help detect fraudulent activity.
Cookies can be "first-party" (set by mcesmr.com) or "third-party" (set by another organisation whose service we use, such as our payment provider). They can also be "session" cookies, which are deleted when you close your browser, or "persistent" cookies, which remain on your device for a set period or until you delete them.
How we use cookies
We use cookies and similar technologies for a limited and clearly defined set of purposes. We do not use cookies to build advertising profiles of you, and we do not sell your data. In summary, we use them to:
- Make the Site work — including loading pages, keeping your session active, and operating the WooCommerce shopping basket and checkout.
- Keep the Site and your purchase secure — including detecting and preventing fraud during payment, and protecting against abuse and security threats.
- Remember your preferences — such as your cookie choices and other settings, so you don't have to set them again on each visit.
- Understand and improve the Site — using privacy-respecting analytics to see, in aggregate, how the Site is used and where it can be improved.
Because we sell digital downloadable products (professional AI prompt collections) delivered instantly online and by email, some cookies are essential to taking payment and giving you access to your purchase. These cannot be switched off without preventing the Site from working as intended.
The categories of cookies we use
We group the cookies and similar technologies on our Site into four categories. The first category is always active because the Site cannot function without it. The other three are optional and are only used where you have given consent.
(a) Strictly necessary cookies. These are essential for the Site to operate and for you to use features you have asked for. They include cookies that keep your session secure, that operate the WooCommerce shopping basket and remember its contents, that carry you through the checkout, that balance load across our servers, and that record your cookie-consent choices so we can respect them. Without these cookies, services you have requested — in particular adding products to your basket and completing checkout — cannot be provided. These cookies do not require consent under PECR and cannot be switched off through our consent banner. If you block them in your browser, parts of the Site, including checkout and delivery of your purchase, may not work.
(b) Functional / preference cookies. These remember choices you make to give you a more convenient experience — for example, your cookie preferences, display or language settings, or that you have already dismissed a notice. They are optional. If you do not allow them, the Site will still work, but some conveniences may not be remembered between visits.
(c) Analytics / performance cookies. These help us understand how visitors use the Site — for example, which pages are visited and whether anything is causing errors — so we can improve it. We use a privacy-respecting analytics approach: data is used in aggregate, we limit or avoid the collection of directly identifying information, and we do not use analytics for advertising. These cookies are optional and are only set with your consent.
(d) Third-party cookies. Some cookies are set by trusted third parties whose services we rely on. The most important is Stripe, our payment provider, which sets cookies to process payments securely and to help detect and prevent fraud during checkout — this is part of providing the payment service you have requested and is treated as strictly necessary. Where we use a third-party analytics provider, any cookies it sets fall under the analytics category above and are only used with your consent. Third parties set these cookies under their own privacy policies; see the links further down this page.
Cookies we use — at a glance
The table below lists representative cookies and similar technologies we use, grouped by category. Cookie names, providers and durations can change as we and our providers update our services, and some names are set automatically by our software; where a specific name is not known in advance it is shown as a placeholder. This table is reviewed regularly and is intended as a clear, honest guide rather than an exhaustive, permanently fixed list.
- STRICTLY NECESSARY — Name/provider: woocommerce_cart_hash / WooCommerce (first-party). Purpose: Tracks whether your shopping basket has contents so the Site can display it. Type: First-party, functional to checkout. Duration: Session (deleted when you close your browser).
- STRICTLY NECESSARY — Name/provider: woocommerce_items_in_cart / WooCommerce (first-party). Purpose: Records the items currently in your basket. Type: First-party. Duration: Session.
- STRICTLY NECESSARY — Name/provider: wp_woocommerce_session_[hash] / WooCommerce (first-party). Purpose: Holds a unique identifier so your basket and checkout details persist as you move through the Site. Type: First-party. Duration: Up to ~2 days (persistent).
- STRICTLY NECESSARY — Name/provider: [cookie_consent_name] / MCESMR (first-party). Purpose: Stores your cookie-consent choices so we apply them and don't ask again on every visit. Type: First-party, preference of consent. Duration: Up to ~6–12 months (persistent).
- STRICTLY NECESSARY — Name/provider: PHPSESSID / Hosting (Hostinger / WordPress) (first-party). Purpose: Maintains your server session so the Site behaves consistently during your visit. Type: First-party. Duration: Session.

- STRICTLY NECESSARY (third-party) — Name/provider: __stripe_sid / Stripe (third-party). Purpose: Fraud prevention — links activity within a single checkout session. Type: Third-party, security. Duration: ~30 minutes (session-based).
- FUNCTIONAL / PREFERENCE — Name/provider: [preference_cookie_name] / MCESMR (first-party). Purpose: Remembers settings and choices (e.g. dismissed notices, display preferences) for convenience. Type: First-party, optional. Duration: Up to ~6 months (persistent).
- ANALYTICS / PERFORMANCE — Name/provider: [analytics_cookie_name] / [analytics_provider] (first/third-party). Purpose: Privacy-respecting, aggregate measurement of how the Site is used so we can improve it. Type: Analytics, optional (consent only). Duration: Up to ~12 months (persistent), or session-based depending on provider.
You can always inspect the exact cookies currently set on your device using your browser's developer tools (usually under "Application" or "Storage" → "Cookies"), which show the live name, provider, value and expiry for each cookie.
Legal basis for using cookies
The legal basis on which we use each cookie depends on its category:
- Strictly necessary cookies — used without consent under regulation 6(4) of PECR, because they are essential to provide a service you have requested (such as operating the basket and completing checkout) or for security. Where these cookies process personal data, our lawful basis under the UK GDPR is our legitimate interests in running a secure, functioning store and in fulfilling your order (performance of our contract with you).
- Functional / preference cookies — used only with your consent.
- Analytics / performance cookies — used only with your consent.
- Optional third-party cookies (e.g. analytics) — used only with your consent. Third-party cookies that are part of the payment service you have requested (Stripe's fraud-prevention cookies) are treated as strictly necessary, as above.
Where consent is the basis, we will not set the relevant cookies until you have given consent, and you are free to refuse or withdraw it at any time without affecting your ability to browse and buy from the Site.
How we obtain and record your consent
When you first visit the Site (and again periodically, or if we make material changes), you will see a cookie consent banner. Until you make a choice, we set only strictly necessary cookies. Optional cookies — functional, analytics and any optional third-party cookies — are not set unless and until you agree to them.
- You can accept all optional cookies, reject all optional cookies, or choose which categories to allow.
- Rejecting optional cookies is as easy as accepting them, and refusing optional cookies will not stop you from using the Site, browsing collections, or completing a purchase.
- We record your choice (using a strictly necessary consent cookie) so we can honour it and avoid asking you again on every page.
Consent obtained in this way satisfies the standard required by PECR and the UK GDPR: it is freely given, specific, informed and given by a clear affirmative action. We do not treat continued browsing, scrolling, or pre-ticked boxes as consent.
How to manage or withdraw your consent
You can change your mind at any time. You do not need to give a reason, and withdrawing consent is as straightforward as giving it.
- Through our consent tool — reopen the cookie settings on the Site (for example via the "Cookie settings" or "Manage cookies" link, usually in the footer) to review your choices and turn optional categories on or off.
- Through your browser — most browsers let you see what cookies are stored, block or delete cookies, and set preferences for future visits. You can usually find these controls in your browser's privacy or security settings.
- Deleting existing cookies — clearing cookies in your browser removes those already stored; the consent banner will then appear again on your next visit so you can set fresh preferences.
Withdrawing consent does not make any prior use of optional cookies unlawful, but it stops further use of those cookies going forward.
Important: please do not block strictly necessary cookies if you intend to make a purchase. If you block them — for example by disabling all cookies in your browser — the shopping basket, checkout, payment and secure delivery of your digital products may not work, and we may be unable to complete your order.
Browser-specific cookie controls
Each browser manages cookies differently. The official help pages below explain how to view, manage and delete cookies in the most common browsers:
- Google Chrome — see Google's Chrome cookie settings help: https://support.google.com/chrome/answer/95647
- Mozilla Firefox — see Mozilla's cookie settings help: https://support.mozilla.org/en-US/kb/cookies-information-websites-store-on-your-computer
- Apple Safari — see Apple's Safari privacy help: https://support.apple.com/en-gb/guide/safari/sfri11471/mac
- Microsoft Edge — see Microsoft's Edge cookie settings help: https://support.microsoft.com/en-us/microsoft-edge/delete-cookies-in-microsoft-edge-63947406-40ac-c3b8-57b9-2a946a29ae09
On mobile devices, similar controls are usually available within the browser app's settings and within your device's privacy settings. To learn more about cookies generally and how to manage them, you can also visit https://www.aboutcookies.org or https://www.allaboutcookies.org.
Third-party cookies and their privacy information
Some cookies are set by third parties whose services we use. We have no control over the cookies set by these third parties, and you should review their own privacy and cookie policies for full details. The main third parties are:
- Stripe — our payment provider, used to process payments securely and to help prevent fraud at checkout. See Stripe's privacy policy at https://stripe.com/gb/privacy and its cookie policy at https://stripe.com/gb/legal/cookies-policy.
- [analytics_provider] — our analytics provider (used only with your consent) for privacy-respecting, aggregate measurement of Site usage. Please refer to that provider's own privacy and cookie information for details of any cookies it sets.
- Hostinger — our hosting provider, on whose infrastructure the Site and store run; certain strictly necessary cookies (for example session and security cookies) may originate from this hosting/WordPress environment. See https://www.hostinger.com/legal/privacy-policy.
We choose providers that take privacy and security seriously, and we keep the list of third parties under review so it stays accurate.
How long cookie data is kept
How long a cookie remains on your device depends on whether it is a session or persistent cookie:
- Session cookies are temporary and are deleted automatically when you close your browser.
- Persistent cookies remain for a set period — typically from around 30 minutes up to about 12 months, depending on the cookie's purpose — or until you delete them, whichever comes first. The indicative durations are shown in the table above.
- Your cookie-consent choice is itself stored in a persistent cookie (typically for around 6 to 12 months) so we can keep applying your preferences; after it expires we will ask you again.
Where cookies feed into personal data we hold (for example order or analytics records), the retention of that underlying data is governed by our Privacy Policy. You can delete cookies from your device at any time using your browser settings.
Do Not Track and global privacy signals
Some browsers offer a "Do Not Track" (DNT) setting or other global privacy signals. There is currently no agreed industry standard for how websites must respond to DNT signals. We therefore rely on the cookie consent banner and the controls described above to give you a clear, reliable way to manage optional cookies. If we adopt support for a recognised standard in future, we will update this policy.
Changes to this Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in the cookies we use, in the technologies or providers we rely on, or in the law and guidance from the Information Commissioner's Office (ICO). When we make changes, we will revise the "Effective date" at the top of this page, and where the changes are material — for example, introducing a new category of optional cookies — we will ask for your consent again through the banner before setting those cookies.
We encourage you to review this page periodically so you stay informed about our use of cookies.
