Analytics storage
Both analytics tools load when you open a page. GA4 uses _ga and _ga_* to distinguish browsers and keep session state. Google documents a default lifetime of two years. Yandex Metrica uses cookies and browser storage for analytics. Yandex documents a one-year lifetime for _ym_uid. Settings and browser restrictions can affect actual storage.
Google Analytics 4 and Yandex Metrica receive information about page views, referrals, devices and interactions. Yandex Webvisor can record interactions such as clicks and scrolling.
