Cookie policy

Last updated 22 October 2026

This Cookie Policy explains how Charnwood Industries Pty Ltd ('Company', 'we', 'us', and 'our') uses cookies and similar technologies to recognise you when you visit our website at charnwoodsystems.io and its subdomains (together, the 'Website'). It explains what these technologies are and why we use them, as well as your rights to control our use of them.

This is Charnwood Systems' own Cookie Policy and it covers this Website alone. Charnwood Systems is the consulting and software engineering practice of Charnwood Industries Pty Ltd, and 'Charnwood Systems' is a registered business name of that company rather than a separate company.

A cookie cannot be shared between two separate domains, so the choice you make here applies across charnwoodsystems.io and its subdomains and nowhere else. You can review and change it at any time on our Manage cookies page.

In some cases we may use cookies to collect personal information, or that becomes personal information if we combine it with other information.

What are cookies?

Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information.

Cookies set by the website owner (in this case, Charnwood Industries Pty Ltd) are called 'first-party cookies'. Cookies set by parties other than the website owner are called 'third-party cookies'. Third-party cookies enable third-party features or functionality to be provided on or through the website (e.g. advertising, interactive content, and analytics). The parties that set these third-party cookies can recognise your computer both when it visits the website in question and also when it visits certain other websites.

Why do we use cookies?

We use first- and third-party cookies for two reasons. Some are required for technical reasons in order for our Website to operate, and we refer to these as 'essential' or 'strictly necessary' cookies. The rest are optional: one measures how visitors use the Website, and the others measure whether our own advertising elsewhere is working and build the audiences it is shown to. Every one of them is listed below, and all of them can be turned off.

How can I control cookies?

You have the right to decide whether to accept or reject cookies. You can exercise your cookie rights by setting your preferences in the Cookie Consent Manager. The Cookie Consent Manager allows you to select which categories of cookies you accept or reject. Essential cookies cannot be rejected as they are strictly necessary to provide you with services.

The Cookie Consent Manager can be found on our Manage cookies page, where you can revisit and change your preferences at any time, and in the notification banner where one is shown to you. Whether a banner is shown, and whether optional cookies run before you have chosen, depends on where you are: this is set out under 'Which third parties set cookies on our Website?' below. If you choose to reject cookies, you may still use our Website though your access to some functionality and areas of our Website may be restricted. You may also set or amend your web browser controls to accept or refuse cookies.

The Cookie Consent Manager groups cookies into three categories: strictly necessary, analytics, and advertising. Which cookies fall into each category on this Website is set out in this policy rather than on that page, under 'Which cookies do we set ourselves?' and 'Which third parties set cookies on our Website?' below.

How can I control cookies on my browser?

As the means by which you can refuse cookies through your web browser controls vary from browser to browser, you should visit your browser's help menu for more information. The following is information about how to manage cookies on the most popular browsers:

In addition, most advertising networks offer you a way to opt out of targeted advertising. If you would like to find out more information, please visit:

What about other tracking technologies, like web beacons?

Cookies are not the only way to recognise or track visitors to a website. The third-party tags listed below work partly through web beacons (sometimes called 'tracking pixels' or 'clear gifs'): tiny graphics files carrying a unique identifier, which let the company that set one recognise that a page was viewed. That is how an advertising tag reports whether one of our advertisements led to a visit here. We put no web beacon in any email we send, so opening one of our emails tells us nothing. In many instances these technologies rely on cookies to function properly, so declining cookies will impair their functioning.

Which cookies do we set ourselves?

Some of the cookies on this Website are set by us rather than by a third party. Most of them are essential: they remember your cookie choice and your display theme. They are always on and cannot be switched off.

One cookie we set ourselves is an advertising cookie, and it is subject to your advertising choice. When you arrive on this Website by clicking one of our Google advertisements, the link carries a click identifier generated by Google. We store that identifier in a cookie named _cw_click on your device for up to 90 days, which is the period over which Google itself attributes a click, so that if you enquire on a later page of this Website we can report to Google that its advertisement led to an enquiry. Our advertisements can point at any page here, including pages with no form on them, which is why the identifier has to survive the page you land on.

What that cookie holds, and what it does not. It holds the click identifier and nothing else. It does not hold your name, your email address, your phone number, your message, or anything else you type into a form, and it is not readable by any script running in your browser. It is set only while advertising cookies are running for you, so if you decline advertising cookies it is never written, and you can remove it at any time by declining on our Manage cookies page or by clearing cookies in your browser. What we report to Google, and what we deliberately do not, is set out in our Privacy Notice: charnwoodsystems.io/privacy-policy.

One cookie we set ourselves is an analytics cookie, and it is subject to your analytics choice. Links we publish in our newsletter, in our social media posts and in our advertisements carry campaign labels in the address (the utm_ parameters), naming the channel and the piece, never you. When you arrive on this Website by such a link, we store a random identifier in a cookie named _cw_visit on your device for up to 90 days after your latest such visit, and keep on our own server, against that identifier, the labels of the first and the latest tagged link you arrived by, the page each landed on and when. If you then enquire on any page of this Website, those labels are recorded with your enquiry, so that we can tell which of our newsletters, posts and advertisements lead to enquiries.

What that cookie holds, and what it does not. It holds a random identifier and nothing else, and it is not readable by any script running in your browser. What we keep against it is the campaign labels, the landing pages and the times: not your name, email address, phone number or message, not your IP address, and not the other pages you view. No third party receives any of it. It is set only while analytics cookies are running for you; if you decline analytics cookies on our Manage cookies page, the cookie is removed and what we kept against it is deleted on your next visit to any page here, and you can also clear it in your browser at any time.

Which third parties set cookies on our Website?

Five third-party tags run on this Website, and they are the whole list. This is the website that carries our advertising, which is why it runs an analytics tag and four advertising ones.

  • Google Analytics (analytics), to measure how visitors use the Website. Visits here are measured in a Google Analytics property held for Charnwood Systems. That property is linked to our Charnwood Systems advertising account with Google, so what it measures can also be used to build the audiences our advertisements are shown to. It receives page-view information and none of the details you enter into a form.
  • X (Twitter) website tag (advertising), to measure the effectiveness of our advertising and to build audiences. It reports into an X advertising account held for Charnwood Systems. It receives page-view information and none of the details you enter into a form.
  • Google Ads (advertising), to measure the effectiveness of our advertising and to build the audiences our advertisements are shown to. It receives page-view information and none of the details you enter into a form.
  • Meta (Facebook) pixel (advertising), to measure the effectiveness of our advertising and to build audiences. This one does more than set a cookie. Meta's automatic advanced matching is switched on, so when you submit a form on this Website the pixel also reads the name, email address and mobile number you entered, hashes each value in your browser, and sends the hashed values to Meta. Meta uses them to match you against its own record of the same details. Hashing here is a matching mechanism, not anonymisation, and Meta is an overseas recipient. What is sent, why, and how to stop it are set out in full in our Privacy Notice: charnwoodsystems.io/privacy-policy.
  • LinkedIn Insight Tag (advertising), to measure the effectiveness of our advertising and to build audiences. It receives page-view information and none of the details you enter into a form.

This list is the tags we actually load, not the accounts we hold. If we switch another one on, it is named here in the same change.

Whether any of these run before you have chosen depends on where you are. If you are in the European Economic Area, the United Kingdom or Switzerland, or we cannot tell where you are, we ask you first and nothing optional loads until you accept. Everywhere else, including Australia, the optional cookies and tags above are treated as accepted unless and until you turn them off. You can turn them off at any time on our Manage cookies page, and if you have declined, none of them load at all.

Do you serve targeted advertising?

No advertising is displayed on this Website. The advertising tags listed above do something different: each tells its platform that a visit happened, so that we can measure whether our own advertisements elsewhere are working and so that the platform can build the audiences those advertisements are shown to. The information collected that way does not ordinarily enable us or them to identify your name, contact details, or other details that directly identify you unless you choose to provide these. The Meta pixel is the exception to that last sentence, and on this Website it is the one to read. As set out under 'Which third parties set cookies on our Website?' above, the details you enter into a form on this Website are sent to Meta in hashed form, and hashing there is a matching mechanism rather than anonymisation.

How often will you update this Cookie Policy?

We may update this Cookie Policy from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal, or regulatory reasons. Please therefore revisit this Cookie Policy regularly to stay informed about our use of cookies and related technologies.

The date at the top of this Cookie Policy indicates when it was last updated.
