If you have a Claude account, they're going to train on your data moving forward

This going to turn into one of those situations where we find out they trained on everyone whether they opted-out or not down the line. I want to keep using Claude, but I also don't want all the solutions I come up with to become common knowledge.

I think I'm fine with the whole getting better due to something helped it / co find with it. I'm not happy if it's directly 1:1 or attributed to me - chatham house rule for this would be great.
