The Russian Federal Service for Supervision in the Sphere of Telecom, Information Technologies and Mass Communications (Roskomnadzor) announced on April 19 that by mid-2018 Twitter will transfer to Russia its databases containing personal data of Russian members.
A message on the website of the Russian agency cites a letter from Twitter representative Sinéad McSweeney that says the company is currently evaluating what data can be transferred to Russia.
Earlier, Roskomnadzor noted that the data set required by Twitter user agreement allows for the identification of individuals, therefore this information comes within the purview of law on the storage of personal data.
The law on the storage of personal data of citizens in Russia has been in effect since September 2015. It obliges companies to store and process personal data of Russian citizens within the territory of the country. Otherwise, Roskomnadzor can block access to online resources that fall under the law.
In 2016, the largest foreign social network LinkedIn was blocked in Russia for the first time. The court found it to be a violator of the law on personal data.
