This page is about the cookies and similar technologies that may be set on your device when you visit a TfL website, and how you can manage them.
This Cookies policy applies to the websites of TfL and its subsidiary companies, including:

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
