The Data Protection Act 1998 is a law in the United Kingdom that says that people must take care of the information that they have about you. It also says that people can only use the information they have about you for certain reasons, like if you gave them permission or if they need it to deliver a service to you. This law also gives you certain rights like the right to know what information people have about you, and the right to ask them to delete it if you don't want them to keep it anymore.
