I have literally zero dependency on the Internet. Everything I value (family and event photos, music, books (hard copies), school report cards, ID cards, etc.) is already with me in hard copies or hard drive. If Internet were to go down, I believe, I will breathe happily!!
If those notes are really worthy and meaningful to you, then hire someone to type them out for you. If there is something that money can buy, then save your time!
I have 12 YO. I have given him both laptop and phone with restrictions.
YouTube = 30 min a day
Roblox = 30 min on weekends
General browsing = Enforced by Kaspersky Safe Kids with all adult content blocked
Total device time = 1.5 hour per day
Anything that takes more time, like scratch programming, school projects, research on topics, etc. is done on my laptop under my casual supervision (I reading a book and he using my laptop and filling his word doc with what he wants to write or doing Scratch programming for example).
Family link for Android works great.
Kaspersky Safe Kids works great for Windows Laptop.
I can enforce device use time, content, app time limits, etc. Has been working like a charm since Covid days.
