Good encryption  serious bugs Telegram is one of he most secure messengers for non-group chats  as messages can be deleted within seconds. The group chats  however  are not at all encrypted. Even WhatsApp is saver. Furthermore  secret chats tend to be closed automatically without apparent reason. You then have to start a new secret chat with he same person. This is absolutely annoying. I do not recommend Telegram as long as these two problems aren't fixed.
