Cookies and Online Tracking

Effective Date: April 7, 2023

The Antidote website may use Cookies, Web Beacons, Pixels, Tags (including server-to-server tag tracking such as Application Programming Interfaces ‘API’), and other similar online tracking technologies. We are required by law to obtain your consent for any online tracking technologies that we place other than those that are ‘Strictly Necessary’. 

This page details what Cookies, Web Beacons, Pixels, Tags and other similar online tracking technologies we may collect, and how and why we use them. We will never share personally identifiable information with a third party, except where you give us explicit permission to do so. To the extent any personally identifiable information is collected through online tracking technologies, our Privacy Policy shall apply. 

How do the different online tracking technologies work?


Cookies are small pieces of data that are stored into your browser when you visit a website, which are stored there for a certain length of time. Cookies allow the website to customize itself to you.

Cookies cannot be executed as code or used to deliver viruses. Cookies cannot give us access to the stored information on your device.

Pixels (also known as 'marketing pixels' or 'tracking pixels'); are short lines of HTML or JavaScript code, which are fired upon a particular website event/or visit. Pixels are used to track and gather website performance through behavioral information about visitors to the website. This then helps in sending custom (i.e. more helpful and interesting) ads to website visitors.

Pixels cannot give us access to the stored information on your device. 


Tags (also known as 'content tags', ‘collaborative tags’ or ‘social tags‘); are also short lines of HTML or JavaScript code used for applying digital labels to online content. All Tags are a form of Pixel - generated after an event/or visit and resulting in a recording of that event/or visit in the form of a Cookie (N.B. but not all Pixels are Tags).

Tags may also include server-to-server tracking (such as Application Programming Interfaces ‘API’) through Google, social media - not limited to Twitter, Tik Tok, Meta (Facebook, Instagram), plus other advertising partners. Tags facilitate searching functionality, plus associations/linking of related content. Tags cannot give us access to the stored information on your device.

How does Antidote use Cookies and other online tracking technologies? 

  1. To record that you are logged in (if you chose to register and log in), so that you don’t need to keep logging in - and so that we can pre-fill certain data in forms. 
  1. To monitor our website’s performance and to help us enhance usability, we collect information on usage patterns using our own and third party analytics software. This includes tracking things like which pages are visited on our site, the sequence in which people explore the site and how long is spent on each page. 
  1. To tailor aspects of the site based on your previous usage patterns and information relating to your location. This includes remembering that you have selected a certain language preference - or setting it automatically because you appear to be based in a certain location.
  2. To offer certain functionality that is provided by third party sites such as social sharing and authentication (e.g. Facebook logins).

Please also note that blocking tracking may adversely impact some functionality on our site (e.g. the ability to register and apply for a clinical trial).
