Cookies allow for a recognition of a specific device or browser. Other tracking technologies include web beacons, Java Scripts, entity tags, and HTML5 local storage.

2. Similar technologies
Similar technologies are technologies which enable tracking user behaviour.
- Web Beacons – Small, transparent images embedded in web pages, applications, and emails that are sometimes called “clear gifs”, “single pixel gifs”, “page tags” or “web bugs”. We use web beacons in marketing emails to track and to test the effectiveness of marketing activities, and to find out if an email has been opened and acted on.
- JavaScript – Code snippets embedded in various parts of websites and applications that facilitate a variety of operations including accelerating the refresh speed of certain functionality or monitoring usage of various online components.
- Entity Tags – HTTP code mechanisms that allow portions of websites to be stored or “cached” within your browser and validates these caches when the website is opened, accelerating website performance since the web server does not need to send a full response if the content has not changed.
- HTML5 Local Storage – Allows data from websites to be stored or “cached” within your browser to store and retrieve data in HTML5 pages when the website is revisited.
