Telegram co-founder Pavel Durov promised the messaging application's Ukrainian users that their personal data is protected from any potential security issues stemming from the ongoing war between Russia and Ukraine, BBC News reports. "I stand for our users no matter what. Their right to privacy is sacred — now more than ever," Durov said in response to concerns raised about whether Telegram's cloud-based platform had sufficient encryption to preserve privacy. While user data is safe, the platform indicated not all of its functions carry end-to-end encryption capabilities.
