FWIW, I've seen a couple threads on Reddit where people did network sniffing -- the echo only had network traffic after the wakeword. So, in a hearsay/amateur manner, it seems to not be doing that.

As someone else mentioned, they could of course record constantly, then compress and transmit in batches, and that would probably go unnoticed.

Possibly, but it can be fingerprinted by using known audio samples and intentionally producing very large amounts of data. See my other reply.
