"Roundonations" is a campaign that showed charity as part of a lifestyle: a simple and convenient way to help as part of daily activities. In a creative way, we have succinctly and vividly shown that, thanks to "Roundonations" in Yandex services, even a small contribution can turn into a big help, and this is the power of transactional charity. The campaign led to an increase in the number of subscribers for rounding up, an increase in donations to the Yandex charity fund “Help Nearby” and it has become a driver of engagement in charity for many young people.
