A calmer classroom day, with nothing to buy and nothing to sign up for.
ClassDa.sh puts a teacher's whole day on the board: the schedule, the class, points, attendance and the quick tools they reach for. It's free, there are no accounts or licenses, and student information stays on the teacher's own devices: it's never sent to us.
No accounts for teachers or students, and no sign-up.
Names, points, attendance and notes stay in the browser on the teacher's computer. We have no database to send them to.
No ads, no trackers and no analytics on the board. The front page, the demo and the site pages count visits, with no cookies and nothing that identifies anyone.
We're happy to sign the SDPC National DPA, or your district's own.
Positive behavior, visibly
Points are positive-first: a child, a table, a group or the whole class, toward a class goal.
A −1 is logged quietly with a reason, for the teacher's records, and never shown to the class.
Children's ages are never shown.
Smoother days
Today's bell schedule and a countdown to the next period, readable from the back of the room.
Learning targets from your state's standards on the banner.
A Drill button with a big headcount, and a silent board, for fire drills and lockdowns.
When a sub comes in
Sub help on the board: how it works, the teacher's letter, and what to do in each block, with no student's private notes on screen.
Printable sub plans, and a teacher lock that keeps reports, minus points and notes behind a PIN.
Records
The teacher keeps the records
Teachers can export a day plan, a bathroom and out-of-class log, and class or single-student reports as PDFs, plus a CSV of points and attendance, for conferences and their own records. Backups are classroom files the teacher saves, so a new laptop or a classroom board is a file away.
AI
AI is optional, and your district's choice
ClassDa.sh never talks to an AI itself. Its AI helpers only give the teacher a prompt to paste into the AI chat your district has approved (for example, to turn a class list or the school calendar they already have into a file the board reads), and read back the answer they paste in. What goes into that AI, class lists included, follows your district's AI policy. Teachers who'd rather not use AI can set up by hand, and the setup guide leaves the AI helpers out.
Next steps
Trying it at your school
Any teacher can try it today in Chrome or Edge: it takes about five minutes to set up, or one tap to look around the demo class.
Your IT team will want the page for school IT teams: one address to allow, and what the board does and doesn't do.
