Cookie Policy

What are cookies?

For a website to work properly, it needs to collect certain basic information about its visitors. To do this, a site will create files known as cookies – which are small text files – on your computer, tablet or mobile device. 

These cookies are designed to allow the website to recognise you on subsequent visits or to authorise other designated websites to recognise you for a particular purpose.

Cookies do a lot of different jobs which make your experience of the Internet much smoother and more interactive. For instance, they are used to remember your preferences on websites you visit often, your user ID or the contents of your shopping basket, and to help you navigate between pages more efficiently. 

They also help ensure that the ads that you see online are more relevant to you and your interests. Some data collected is designed to detect browsing patterns and approximate geographical location to improve user experience.

How we use cookies

We may use cookies, web beacons and similar technologies to collect, use and share certain information about your device(s), your use of our websites, app(s) or services, and other unique identifiers personal to you with third-party platforms so that they may target ads to you and to others, based on other information that third party may hold about you. 

In some cases, these third-party platforms may also collect some or all of the above information using cookies or similar technologies. Where they do so, the collection, use and protection of your information is governed by those third parties' privacy policies and practices, and not our privacy policy.

You may be able to opt-out of third-party advertising technologies (including cookies) which remember your browsing habits and try to display relevant ads when you use our websites, app(s) or services by visiting www.youronlinechoices.com/uk/your-ad-choices

If you choose to turn off these technologies, you may still be served ads but they are unlikely to be tailored to your interests.

We don't store information that could be used to identify you personally, but we do use the information we gather to help improve your experience of our website. For example, they help us to identify and resolve errors, or to determine the most relevant information and services to show you in the future.

What types of cookie are there and which do we use?

Most cookies fall into two different categories:

  • first-party cookies which are set by the website you’re visiting and can only be read by that site
  • third-party cookies which are set by someone other than the owner of the website you’re visiting.

These cookies can stay on your machine for varying amounts of time, dictated by whether they are:

  • a persistent cookie which remain on your device for a set period of time specified in the cookie. They are activated each time you visit the website that created that particular cookie
  • a session cookie which are temporary. They allow website operators to link your actions during a browser session. A browser session starts when you open a browser window and finishes when you close the browser window. Once you close the browser, all session cookies are deleted.

Cookies also have, broadly speaking, four different functions and can be categorised as follows: 

Essential cookies

Essential cookies are strictly necessary to enable you to move around the website and use essential features. These cookies don’t collect any information that is used to identify you personally. Accepting these cookies is a condition of using this website. If you prevent these cookies, we may be unable to protect your privacy or predict how our website will perform during your visit.

Performance cookies

Performance cookies collect data for statistical purposes on how you use a website. They don’t contain personal information such as names or email addresses and are used to improve your user experience of a website.

The information collected by our performance cookies includes:

  • number of visitors
  • length of time spent on the site
  • which pages have been viewed 
  • where visitors have come from
  • types of device visitors use.

Information supplied by performance cookies helps us to understand how you use the website. For example, whether you've visited the site before, what you looked at or clicked on, and how you found us. We can then use this data to help improve our services and try out different ideas. 

We generally use independent analytics companies (such as Google Analytics) to perform these services for us and when this is the case, these cookies may be set by a third-party company and are therefore third-party cookies.

Functionality cookies are used to anonymously recognise you, so you're able to use certain on-site functionality, such as live chat, watching a video or taking a donation payment. They are also used to remember your preferences or settings when you return to our site, so that we can provide you with a more personalised experience.

Targeting or advertising cookies

Advertising cookies are used to deliver adverts and marketing that is more relevant to you. They can also limit the number of times you see a particular ad and measure the effectiveness of an advertising campaign by tracking clicks. 

If you switch these cookies off, the ads you encounter online will be less relevant to you and your interests.

They are usually placed by third-party advertising networks with a website operator’s permission, but can be placed by the operator themselves. They can remember that you have visited a website, and this information can be shared with other organisations, including other advertisers. They cannot determine who you are though, as the data collected is never linked to your profile.

The main ways we use advertising cookies are set out below:

  • Interest-based advertising (or online behavioural advertising) is where cookies are placed on your device by our third-party service providers. These remember your online browsing activity and group together your interests in order to provide you with targeted advertisements which are more relevant to you when you visit thebraintumourcharity.org. Your previous browsing activity can also be used to infer things about you, such as your demographics (age, gender etc). This information may also be used to make the advertising on headsmart.org and askBRIAN.org more relevant to you.
  • ‘Retargeting’ is a form of interest-based advertising that enables us to show you ads based on your online browsing activity away from our website. This allows companies to advertise to people who previously visited their website. These cookies will usually be placed on your device by third-party advertising networks.
  • Social media cookies help us advertise our products and services to members of our community who are on social media, for example, promoting our support services or fundraising events. These cookies help social media operators (Facebook for example) recognise users who have visited The Brain Tumour Charity website and serve them adverts on our behalf. We participate in Facebook’s Custom Audience and Lookalike Audience programmes so that you can receive relevant ads from us when you use Facebook, and so that we can raise awareness among other Facebook users who share similar interests to you. We provide personal information such as your email address to Facebook to enable them to determine if you are a registered account holder with Facebook. Our adverts may then appear when you access Facebook and on your Facebook feed. Your data is sent in an encrypted format that is deleted by Facebook if it does not match with a Facebook account. For more information please read the Facebook Business page about Custom Audiences and Facebook's Data Policy.
