Channels are not fully encrypted, end-to-end. All communications on a Telegram channel can be seen by anyone on the channel and are also visible to Telegram. Telegram may be asked by a government to hand over the communications from a channel.

Because Telegram has this data, it may also be stolen by hackers or leaked by an internal employee.
