Google cookies track user activity, authentication, and preferences

Authentication and Security Cookies

Several cookies manage user accounts and prevent unauthorized access. The __Host-3PLSID and __Host-GAPS cookies are used to sign in with a Google account and last for one year. Google Authentications utilize the session-based G_AUTHUSER_H cookie, while LSOLH is for authentication with your Google account. Additionally, the __Secure-ENID cookie functions for 11 months to prevent fraudulent login attempts, containing a Google user ID utilized for statistics and marketing purposes following a successful login.

Tracking, Statistics, and Advertising

A significant portion of the tracked identifiers deal with metrics, conversion rates, and ad targeting. Cookies such as OSID, DV, LSID, COMPASS, __Secure-OSID, NID, and SNID are deployed to collect website statistics, track conversion rates, and handle Google ad personalization over durations ranging from two days to one year. Other targeted files include _gcl_dc and _gcl_au for Google AdSense advertisement efficiency experiments, TAID to link user activity across devices for ad coordination, and _dcid to collect user behavior information across multiple websites to optimize advertisement relevance.

Preferences and Functional Cookies

Cookies like SID, SAPISID, and AID remain active for one to two years to download specific Google tools and save user preferences, such as search results per page or SafeSearch activation, while adjusting Google Search advertisements. Location-based functionality is managed by the UULE cookie, which sends precise browser location information to Google servers depending on browser settings. Furthermore, Flipped or consent-related functions rely on items such as CONSENT for a 20-year tracking period, along with FCCDCF and FCNEC for the Google Funding Choices API handling GDPR consent and CCPA opt-out gathering.
