Cookie management

There has been a lot of discussion about cookie management latety. Some notions first:

  • First-party cookies are cookies whose domain matches the domain name of the Website on which they are used. For example, if you visit a site called <www.acme-corp.com>, a first-party cookie would target the domain *.acme-corp.com
  • Third-party cookies are cookies that target a domain name that is not the domain name of the Website on which they are used. For example when visiting the <www.acme-corp.com> website, a third-party cookie would point to the *.advertising.com domain and when visiting <www.other-company.com> a JavaScript from advertising.com might also make use of a *.advertising.com cookie.

The cookies we use with Hermes are first-party cookies. The JavaScript that is executed is indeed hosted at hermes.allo-media.net, but it creates a cookie that matches the domain *.acme-corp.com. This is possible because the JavaScript is loaded and executed by the document hosted at <www.acme-corp.com>.

For the same user, we would create a different cookie if the user also visited <www.other-company.com>.

Privacy protection

Allo-media provides a "cohort mode", which let's you run the script without cookies. Some features are not available in this mode, but you'll be able to get basic tracking of your calls.
