Snapchat’s parent company says the US messaging app has been registered with Russia’s technology regulator without its knowledge.
The move means Snapchat will be required to keep all messages for six months and make them accessible to the Russian security services.
Snap said it had no intention of complying with the rule.
A spokesman for the company said it had provided “very basic contact information” to Roskomnadzor, but “not for the purpose of registering us”.
Russia’s new data laws require “information distribution organisers” to register with the regulator and store users’ data for six months. The requirements come into force next year.
Companies must also hand over their encryption keys when asked, in line with Russian anti-terror legislation.
Non-compliance comes with a risk. Chinese messaging service WeChat was blocked earlier this year, Russian website VC.Ru reported [in Russian].
