No formulas to break. No subscription.
School spreadsheets break when a formula is typed over, paper registers go missing, and school software charges per student every month. This opens from a double-click, works offline and keeps students’ records on the office computer.

Questions
Something else? Email us and we'll answer before you buy.
Where is my data stored? Is it private?
Everything is saved inside your browser on this device. Nothing is uploaded and there is no account, so no company holds a copy of your students’ records. They are not encrypted, though: anyone who can use this device and browser can open them, so keep the device locked. Download a backup regularly (Settings → Data & backup → Back up now) and keep it somewhere as safe as the records themselves.
Does it work without internet?
Yes. Open index.html and it runs fully offline. You can also host the folder on any website and choose “Install app” in Chrome or Edge to get a desktop or phone icon that works offline.
Can I use it on my phone or iPad?
Yes. The layout adapts to phones and tablets with a bottom navigation bar. Each device keeps its own data, so use Back up / Restore to move records between devices.
How do I start fresh after trying the sample data?
Go to Settings → Data & backup → Erase records. Every sample record is removed, and so are the sample school’s name and contact details, so nothing of theirs ends up on your report cards or receipts. Your other settings are kept.
Is this for one teacher or for the school office?
The school office, running the whole school: every class, register, timetable, report card and fee, plus the library, bus routes, behaviour and the health room. A single teacher planning lessons is better served by our Teacher Lesson Planner, a parent teaching at home by the Homeschool Planner, a student by the Homework & Assignment Tracker, and a childcare centre’s drop-off and pick-up by Daycare & Childcare Management.
How is attendance worked out?
Each register starts with every student present. A student’s attendance is the share of registered days they were present this school year. Late arrivals count as present and excused absences as absent unless you change either in Settings → Attendance. A student is flagged for chronic absence once they have the number of school days you set and fall under your threshold (90% to start with).
How are averages and grades worked out?
Each mark is turned into a percentage of what it was marked out of and multiplied by the assessment’s weight; the weighted percentages are added and divided by the weights. Blank marks are left out. A student’s overall average is the average of their subjects, and the grade comes from the scale in Settings → Grades and report cards.
Can several staff use it at once?
Each device keeps its own records, and there is no live sync between computers. Most schools keep it on the office computer; teachers hand in registers and marks, or the office moves records with Back up now and Restore.
How many students can it hold?
It was tested with 600 students on the roll and stays quick: the dashboard, the register and the marks grid open in a fraction of a second.
Does it do payroll or the school’s accounts?
No. It bills families for fees and records their payments, with receipts and statements. Staff pay and the school’s bookkeeping belong in your accounting software.
Can customers book or pay online through it?
No. It runs offline on your own device, so there is no booking page for customers and it does not take card payments. You record bookings and payments in it yourself, including ones taken by phone, card reader or another website.
