How your feed is generated
The Yandex app gradually adapts the feed to your interests. It analyzes your interaction with the feed and with Yandex services, search queries, browser history, and other data on your online preferences. As a result, you receive a personalized selection of cards. If your interests change, the feed adjusts to them over time.
Personalization works when you're logged in to Yandex. You don't need to worry about privacy because the data is stored in a depersonalized format. If you use the app on different devices, log in to each of them using the same account. This makes the feed adjust to your interests much faster.
