Some cookies are used to store a user's preferences. For example, a cookie called "NID" is saved in the browser of most users of Google services.

Google SafeSearch (on or off). "NID" cookies expire six months after their last use. YouTube uses a cookie named "VISITOR_INFO1_LIVE" for a similar purpose, and in order to detect and fix problems with the service.
YouTube uses the "PREF" cookie to store information such as user preferences for page setup and playback (autoplay, shuffle content, and player size). In YouTube Music, these preferences include volume, repeat mode, and autoplay. This cookie expires eight months after its last use.
Some cookies are used to maintain and improve the user experience during a specific browsing session. For example, YouTube uses the "YSC" cookie to remember the data entered by the user and to associate the actions of the user with it. This cookie remains active as long as the user's browser is open.

Security
Security-related cookies are used to authenticate users, prevent fraud and protect Internet users who interact with a service.
Some cookies are used to authenticate users and ensure that only the account holder can access them. For example, "SID" and "HSID" cookies contain, in encrypted and digitally signed form, the user's Google account ID as well as the date and time of their last connection. Combined, these cookies allow us to block many types of attacks, such as attempted data theft when filling out forms in Google services.

These two cookies prevent malicious sites from impersonating the user and acting without his knowledge.
To analyse
Cookies used for analytical purposes help collect data to better understand Internet user interactions with a particular service. This information enables the services to provide better quality content and features that improve the user experience.
Some cookies allow site managers to better understand user interactions with their properties. For example, Google Analytics is a Google product that allows site and application owners to understand the behavior of Internet users using a service. Google Analytics uses cookies to collect information and generate reports on site traffic statistics, without transmitting the identity of visitors to Google. The "_ga" cookie is the most used by Google Analytics. It allows a service to distinguish one user from another and remains active for two years. It is used by all sites using Google Analytics. This is the case with some Google services.
Google services also use these analytics cookies, as well as other cookies, such as "NID" in Google search and "VISITOR_INFO1_LIVE" on YouTube.

We use the "NID" cookie to present Google Ads ads in Google services to users who are not logged in.
We use "IDE" and "ANID" cookies to serve Google Ads ads to users on non-Google sites.
Other Google services such as YouTube may also use these cookies and "VISITOR_INFO1_LIVE" type cookies to improve the relevance of the advertisements displayed.
If you have enabled personalized ads, the "ANID" cookie is used to remember this setting. It remains active for 13 months in the European Economic Area (EEA), the United Kingdom and Switzerland, and for 24 months everywhere else. If you have disabled personalized ads, the "ANID" cookie will be used to save this setting until 2030. The "NID" cookie expires six months after it was last used. The "IDE" cookie remains active for 13 months in the EEA, the United Kingdom and Switzerland, and for 24 months elsewhere.
Some cookies used for advertising are intended for users who log in to access Google services. A "DSID" cookie, for example, is used to identify a user logged into their Google account on non-Google sites and to remember their ad personalization preferences. This cookie remains active for two weeks.
Businesses can use Google's advertising platform to advertise on Google services, as well as on partner sites.
Some cookies allow Google ads to be displayed on third-party sites and are set in the domain of the website you are visiting. For example, "_gads" cookies allow sites to display Google ads, including personalized ads. Cookies that begin with "_gac_" come from Google Analytics. Advertisers use them to measure user activity and the performance of their advertising campaigns. The "_gads" cookies remain active for 13 months and the "_gac_" cookies for 90 days.
Some cookies are used to measure the performance of campaigns and advertisements as well as the conversion rates of Google ads on a site you visit.

The cookies used to measure conversion rates are not used to personalize advertisements. The "_gcl_" cookies remain active for 90 days.
