security measures for minors


I coached elementary for a few years and I had my kids use that.
Kids prefer chess.com coz they see it has more features, freedom, and interactions with people from various backgrounds
I too found any platform or community for kids only to be boring

I used chesskid, I was happy with that, but be sure to look at both. I don’t know much about chesskids.

There is a Safe Mode feature in Settings, but I don't think there is a way to prevent the account holder from changing that setting, so you would need to monitor site use all the time to make sure they didn't turn it back on.
But chesskid is probably your best bet.
