This is stated in the message of the regulator.

Roskomnadzor reported that the Saratov District Court recognized the information contained in this application as prohibited for distribution in Russia.

This also applies to the application itself, as it allows access to prohibited content and facilitates the commission of criminal offenses, the regulator explained.

In December, Roskomnadzor announced that access to The Tor Project resource was restricted in Russia by a court decision.
