Short answer
Create a free account at /schools/signup and choose Co-op or microschool. Strict student rules are on from the first minute: games, social media, AI companion apps, VPNs and adult sites blocked, with SafeSearch forced. Change one setting on the router where you meet, and share your link so families can protect home too.
Why co-ops need it
Kids bring their own phones and tablets, and the Wi‑Fi password gets passed around. Without a filter, the co-op network is the least protected place in a child's week.
What's on from the start
- Games, including "unblocked games" mirror sites, and the browser games kids pass around.
- Social media, AI companion apps, VPNs and web proxies.
- Adult content and gambling, with SafeSearch and YouTube Restricted Mode forced.
- A light Staff setting for teachers' and parents' own devices.
Need a site for a lesson? Allow it in one tap. Want games back at lunch? Use a schedule.
Meeting in a church or rented space?
Ask whoever runs the building's router to paste your DNS address, or bring a small travel router of your own and set it up once. Every device on that Wi‑Fi is filtered wherever you plug it in. The school network guide walks through the setting.
Help families at home
Your co-op gets its own link and QR code. Parents set up the same protection at home in five minutes, free, and you see how many families joined, never what they do.

We don't take E-Rate. Do we need CIPA?
No. CIPA only applies to E-Rate funding. You still get the same strict filtering and the printable report if you'd like a record for parents.
Can each family's own devices be filtered at home too?
Yes, through your share link. Each family makes its own free account and controls its own settings.
