In many countries, there are cookie laws and/or privacy laws that prescribe to the website owner or the person responsible for a website to give information about those resources. This is also the case for countries that still have an opt-out regime for cookies. The page with information can be reached via a link on the cookie banner, via a link in the Privacy Statement, or via a button or link placed in a menu of your website.
Generally speaking, it should at least give information about the function and the purpose of the used resources. A function is a particular task a cookie has. So a function can be “store the IP address”. Purpose can be seen as the Why behind the function. So maybe the IP address is stored because it is needed for Statistics, or it is stored because it is used for marketing/tracking purposes, or it is needed for functional purposes. It should also give information about retention: how long will the cookie or resource be used or be accessible, and will the data be accessible to third parties, or even sold to third parties? In some countries, it should also give information about the rights the website visitor has. In certain jurisdictions such as California, you should also give information about the data you have sold to other parties, and give the possibility to opt-out using a Do Not Sell My Information button or page. There are also jurisdictions where you are obliged to let website visitors know how you are dealing with browser requests such as Do Not Track!
