Some of Yandex's other services — in particular Yandex.Mail and Yandex.Disk — are included in the registry of so-called "organizers of the spread of information" maintained by the federal censor, Roskomnadzor. This means that they are subject to additional obligations to law enforcement agencies. In accordance with the so-called Yarovaya law, which came into effect on July 20, 2016, the FSB's Center for Operational and Technical Activities can require any service included in the registry to provide it with "information necessary for decoding the received, transmitted, delivered and/or processed electronic messages of Internet users." In essence, this means these services have to hand over the encryption keys for user correspondence to the authorities.
