The two main reasons for cookies #
There is a lot of confusing information about cookies at the moment, but there are generally two main reasons for cookies.
The 1st and most important reason is to allow you to be identified by an App or Website. After logging in, a cookie is set, secure to only you and your browser (a 1st party cookie). This 1st party cookie allows you to load a new page on the website or even come back the next day and still be logged in. Without 1st party cookies, you would have to type in your username and password on every page load.
The 2nd main reason for cookies is for tracking and advertising. These are cookies set by advertising platforms and are generally used to make educated guesses on which advert to show you based on the sites you visit. These are referred to as 3rd party cookies. Your actions do not set them; generally, they are automatically set by just viewing an advert placed on-page by the site owner.
A typical scenario of the 3rd Party Cookie:
You may book a flight on “www.my-airlines.com” which places advertising scripts on their site from something like Google Ads. The Google Ads script will set a 3rd party cookie to identify your browser and session. Later you may visit a completely different website which also has advertising on it by Google Ads. Unfortunately for the airline company, there is no way for them to tell Google Ads that you already bought a flight ticket, but they may also be running an advertising campaign to target people who visited their site. The result is you see adverts for flights you already bought. This is the basics of the 3rd Party Cookie.
What cookie type does Liffery use? #
Liffery does not make money from adverts, so we don’t need to use tracking or advertising cookies.
When you load the Liffery Sidebar, it only wants to read the 1st party cookies set by you upon logging in. It needs to do this to ensure you see what belongs to you and stop others from seeing your content.
