I want a secure messaging app, should I use Telegram? But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. In 2018, Russia banned Telegram although it reversed the prohibition two years later. But the Ukraine Crisis Media Center's Tsekhanovska points out that communications are often down in zones most affected by the war, making this sort of cross-referencing a luxury many cannot afford. Messages are not fully encrypted by default. That means the company could, in theory, access the content of the messages, or be forced to hand over the data at the request of a government.
