Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats you’re having with folks are not as secure as you may believe. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. The Russian invasion of Ukraine has been a driving force in markets for the past few weeks. I want a secure messaging app, should I use Telegram? Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp.
