The small wins that happen on the mat

A first board break. A form finally clean. A kid who bows in without being asked. With ClassDojo, your instructors send the photo and the note home the same day, so families get to be part of it.

Frequently asked questions

Is ClassDojo free for our school?
Yes. ClassDojo is free for your school, your instructors, and your families. ClassDojo offers optional services directly to families, like ClassDojo Plus and Dojo Tutor, and that's what keeps it free for everyone else. We never sell personal information, and we never share it with advertisers.

Which age groups does ClassDojo work for?
Schools use ClassDojo with every age they teach, from little kids' classes through teens. Instructors choose what each group's families see, so the experience fits the students in the room.

How do our staff get set up?
Each staff member creates an account and sets up their group in a few minutes — no IT project, no training day.

How do families join?
Staff share an invite link or code, and families connect from the free app on their phone. Many families already use ClassDojo with their child's school, so there's often nothing new to download at all.

How is our program's data protected?
Your program's information belongs to your program. ClassDojo is COPPA-compliant, never sells personal information, and never shares it with advertisers — see our privacy and security page for the full detail.

Our families already use ClassDojo at school. Do they need anything new?
No. They connect to your school from the same free app they already have, so your updates land right alongside their school's. Nothing new to download, and no second password to remember.

We're a business, not a school. What's the catch?
There isn't one. ClassDojo is free for your school, your staff, and your families, whether you're a nonprofit or a for-profit business. Optional services families can choose for themselves, like ClassDojo Plus and Dojo Tutor, are what fund it. We never sell personal information, and we never share it with advertisers.
