I've been using ZCode since it's initial release and can't find any of this in my data. There aren't any logs showing capture or upload, and I don't even have a ~/.zcode/v2/checkpoints/ directory.
So unless they've cleared it all with a recent update then it doesn't seem to affect everyone.
Is there actually any proof of this, beside this Claude written website and a random x post from some unknown person? Would be nice to have confirmation from someone with a reputation. It's probably true, but you never know...
Not that I've seen. The only follow up I've seen from someone was it only happened if you had a free account and not paid (which would explain why I'm unaffected)
