What cookies are

When we provide services, we want to make them easy, useful and reliable. Where services are delivered on the internet, this sometimes involves placing small amounts of information on your device (eg computer or mobile phone). These include small files known as cookies, and other technologies which conduct a very similar function of understanding people's behaviour while using websites and mobile applications. They can sometimes be used to provide information about your device or its approximate location through the unique IP address associated with it.

These pieces of information are used to improve services for you by, for example:

  • Enabling a service to recognise your device so you don't have to give the same information several times during one task
  • Recognising that you may already have given a username and password so you don't need to do it for every web page requested
  • Remembering your previously searched journeys on our journey planner so you can complete the same search quicker and easier
  • Storing bus routes, roads and tube lines that you have chosen to add to your favourites on your device so the TfL website will be personalised on your device when you next return
  • Measuring how many people are using our online services, so they can be made easier to use and there's enough capacity to ensure they are fast
  • Analysing anonymised data to help us understand how people interact with our site so we can make it better

Changing your cookie settings

We use cookies based on your 'implied consent'. This means that if you continue to use our website, we will assume you are happy for us to set cookies. If you aren't, then there are a number of things you can do. We currently have plans to update the way you give consent for us to use cookies - to make it easier and clearer.

You can set your web browser (eg Chrome, Firefox, Internet Explorer etc) to disable all cookies; allow only 'trusted' sites to set them; or to accept cookies from websites only for the duration of your visit. However, please be aware that if you choose to delete or restrict cookies, some features of our website may not work.

You can also visit the AboutCookies website, for more information about cookies and how to manage them.

We sometimes use external suppliers to deliver services on our behalf, which means these cookies may be set by a third party (third-party cookies). We do not control these cookies so if you would like more information about them or information on how to opt out, please see their individual privacy policies (listed below).

Our cookies and what they do

Strictly necessary cookies

Without these essential cookies, our website won't work properly. They help you move around secure areas of the website and carry out specific tasks, like journey planning or making a payment.

Strictly necessary local storage

  • BIGipServerSSO_Account_Pool

What they do:

  • Remember information you've entered in a form or details about a payment you want to make. Without them, this would be lost every time you moved to a new page
  • If you're signed in to a secure area, like Oyster online, they recognise that you have already signed in. Without them, you'd need to sign in each time you moved to a new page

Embedded content

Sometimes, we embed images or videos from websites such as YouTube. As a result, when you visit a page featuring such content, you may be presented with cookies from these websites. We do not control these cookies and cannot prevent these sites or domains from collecting information on your use of this content.

You should check the relevant third-party website for more information about them and how to opt out. If you are not logged in to their services, they will not know who you are but may still gather anonymous usage information (eg number of views, plays, loads etc).

Social networking and sharing tools

On some pages, we also feature embedded 'Share' buttons or widgets that enable you to share content with friends through a number of popular social networking sites (eg Google+1; Twitter; Facebook 'Like' etc).

These sites may set cookies which can identify you as an individual when you are also logged in to their services. This means they may be collecting information about what you are doing all around the internet, including on TfL sites. We do not control these cookies and you should check the relevant third-party website to see how your information is used and how to opt out.
