What is a cookie?
A cookie is a small file that can be placed on your device that allows us to recognise and remember you. It is sent to your browser and stored on your computer’s hard drive or tablet or mobile device. When you visit our sites, we may collect information from you automatically through cookies or similar technology.
How do we use cookies?
We use cookies in a range of ways to improve your experience on our site, including
Keeping you signed in
Understanding how you use our site
Showing you journalism that is relevant to you
Showing you Guardian products and services that are relevant to you
Working with partners to serve you relevant advertising
Ultimately, this allows us to publish the journalism that you read on our sites and apps.
In the next section, we explain in more detail how we use cookies and similar technology on our sites and apps for a number of purposes.
Other organisations also collect user information on our sites through cookies, tags and pixels. Tags and pixels, also known as web beacons, are similar to cookies but are collected through embedded images.
Using cookies and other technology allows other organisations to help us to analyse how our site is being used, measure the number of visitors to the site, and display advertising.
Cookies that are used by the Guardian are referred to as “first-party cookies” and those that are used by our partners are “third-party cookies”. Because of how cookies work, our website cannot access third-party cookies; nor can other organisations access the data in the cookies we use on our website. There are more details about both in the following sections.
What types of cookies do we use ?
We use four types of cookies, which we describe in this section.
Essential – cookies that are essential to provide you with services you have requested. For example, these include the cookies that make it possible for you to stay logged into your Guardian account and make comments. If you set your browser to block these cookies, then these functions and services will not work for you. In particular, we won’t be able to save your preferences about cookies.
Performance - cookies which measure how often you visit our sites and how you use them. We use this information to get a better sense of how our users engage with our journalism and to improve our sites and apps, so that users have a better experience. For example, we collect information about which of our pages are most frequently visited, and by which types of users. We also use third-party cookies to help with performance. For example, the Google Analytics cookie gives us information such as your journey between pages and whether you have downloaded anything (details of how to opt out of it are below).
Functionality – cookies that are used to recognise you and remember your preferences or settings when you return to our site, so that we can provide you with a more personalised experience. For example, if you are based in the United Kingdom, we will remember this and make sure that you receive the UK homepage when you visit our site, rather than the US or Australia homepage. A mix of first-party and third-party cookies are used.
Advertising – cookies that are used to collect information about your visit to our site, the content you have viewed, the links you have followed and information about your browser, device and your IP address. We have set out more details on this below.
How do we use cookies for advertising?
Cookies are a key part of how we deliver advertising on our sites. Among other uses, they allow us to show more relevant advertising to people who visit theguardian.com by showing you adverts that are based on your browsing patterns and the way you have interacted with our sites and apps. We can then show you adverts which we believe may interest you.
From the very first edition of the Manchester Guardian, published in 1821, our journalism has been funded in part by advertising. Our editorial content is not influenced by the advertising we display and our journalists are free to, and often do, challenge the activities of companies and organisations that advertise and sponsor content that appears in Guardian sites and publications.
As you browse our site, some of the cookies and similar technology we place on your device are for advertising, so we can understand what sorts of pages you read and are interested in. We can then display advertising on your browser based on these interests. For instance, if you have been reading a lot of food and drink articles, you may be shown more adverts for food and drink.
We are a partner in the Ozone Project that may use cookies, pixels and similar technology (see ‘Ozone Project’ and its service provider ‘Lotame’ in the table below) to collect information about what your have viewed and how you have used our sites and our app. They will make assumptions about your interests and preferences and add you to groups based on those assumptions, in order to show you advertising. For example, if you look at a page in our travel section you might be added to a group for people interested in holidaying abroad, and then we might show you adverts for holidays abroad.
The advertising techniques we use do not collect information such as your name, email address, postal address or phone number. We sometimes use information such as your IP address and browser type and also sometimes share some limited aspects of this with third parties for advertising purposes.
There are times when we want to reach Guardian readers who use social media to market our own products and services such as our live events, Guardian Soulmates and Guardian Jobs. We use cookies to help with this.
For example, we place a pixel on our web pages that allows Facebook to place cookies on web browsers. When a Guardian reader who uses Facebook returns to Facebook, Facebook can identify them as part of a group of Guardian readers and on behalf of the Guardian they can serve them with marketing messages from us. The data that can be obtained from a visit to the Guardian is limited to the URL of the pages that have been visited and, in some cases, the status of any unfinished or completed commercial transactions undertaken with us, together with the limited information a browser might pass on, such as its IP address. If you are a Facebook user you can opt out by following the link below.
We may also share online data collected through cookies and similar technology with our advertising partners. This means that when you are on another website, you may be shown advertising based on your browsing patterns on theguardian.com. We may also show you advertising on theguardian.com website based on your browsing patterns on other sites that we have obtained from our advertising partners.
Online retargeting is another form of online advertising that allows us and some of our advertising partners to show you advertising based on your browsing patterns and interactions with other sites. The use of cookies may mean that when you are on another site, you may be shown advertising based on what you have looked at on theguardian.com.
For example, if you have visited the website of an online clothes shop, you may start seeing adverts from that same shopping site displaying special offers or showing you the products you were browsing. This allows companies to advertise to you if you leave their website without making a purchase.
The Guardian app integrates third-party software that provides us with information about how the app is used and what content you have viewed for the purposes of online advertising and analytics, in a similar way to the sites. It uses cookies from some of the providers listed here, among others.
Increasingly, our readers fund us directly – either by buying a newspaper, or taking out a print or digital subscription or through making one-off, regular or monthly contributions. But to grow that number of supporters we are reliant on marketing, and we still rely in part on advertising to fund our journalism.
