Alice offers a few different STT options.
While you can stay completely offline, depending on the language and your background noise, indeed the results are not as perfect as the cloud ones. But especially coqui STT (former deepspeech) does a really good job!
Another option, if you are a bit more open with "sharing" data and you don't want to miss out the best TTS, is enabling google or azure cloud services - with the big difference, Alice will only send the sound right after detecting your hotword (only while flashing her LED and asking you "yes?" before the recording starts). Nothing else would be shared.
