Other replies already addressed the screen time/hanging out together aspect, so I will comment on being unsupervised. I was a kid on the early-ish internet and I was free to "surf the interwebs" unsupervised. The internet is not the same anymore but I think the general rules still apply. This was a very valuable learning experience for me. Based on my own experience (anecdata, I know) what I found really helped me is grownups around me explaining things clearly and hammering a few facts into my brain: 1. Don't put anything about your real self on the internet (this is increasingly harder due to social media, I'm glad I was just on IRC back in the day). 1a. What goes in the internet will stay in the internet forever. Mind the info you get out there, even if it's supposed to be a private message. Leaks happen. 1b. Encourage them not to use their real name and address, to be pseudonymous at the least (or better, completely anonymous). Help them set up accounts that don't link to their identity (specially email which is the center of your online identity nowadays). 2. Not everyone on the internet is who they say they are. On the internet nobody knows you're a dog. 2a. Be clear on what grooming and pedos are and that they're out there to catch you off-guard. 2b. Show them what spam, scams, malicious sites, phishing, etc. look like and how to prevent damage. 3. No matter what happens or how deep in shit they are they can come to you for help. You won't approve the ugly things they do, but you will forgive them and help them clean up the mess. If in doubt, come get help. The earlier you ask for help, the faster the cleanup. Make all of this real by showing them what could happen. Show them real cases (there's plenty on the news) and the consequences. Show them how easy it is to trick the other side of the conversation. E.g. it was eye-opening for me to watch a friend of my brother pretend he was an MD from a completely different city on the IRC. He was just a horny teen looking to meet women. He often joked about how we were probably chatting with other men lying about their identity too. Once your kids are old enough to understand this then they can go on the internet 100% unsupervised (it was around 8-9 y/o for me but everyone is different). This will take a while given your kids' age, but we all know time flies. Better get them ready before the time comes!
