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, for example, computer or tablet. These include small files known as cookies or tracking technologies. They cannot be used to identify you personally.
These pieces of information are used to improve our services to you, including:
1. enabling a service to recognize your device so you don't have to give the same information several times during one task;
2. recognizing that you may already have given a user name and password so you don't need to do it for every web page requested;
3. measuring how many people are using our services, so they can be made easier to use and to ensure enough capacity.
By understanding how people use Secret Files from World Wars to Cold War, we can improve the information provided. This also ensures that the service is available when you want it and fast. We use a number of different methods of gathering this data; see below for details:
