Yes, they have multiple download buttons and it takes a bit, but I got the same with Google; it only took a few minutes to download the data once made available. I was most surprised by the sheer amount of audio data kept: in my case, more than 5Gb of wave files dating back to when I set up my first Alexa 6 years ago. I believe at least 50% of everything Alexa heard in my house is recorded there. That's when I started looking for an offline alternative, since -after the initial novelty wore off- we're only using it to listen to music, turn on/off smart home lights and ask the occasional random question (convert C to F, etc.).
