ClassOS

What it does

Enquiries

Every call and walk-in with its source, course of interest, class and counsellor; a follow-up log with the next date; lists of follow-ups due today and overdue; lost enquiries with the reason; and admission in one step from the enquiry.

Admissions

Student profile with photo, date of birth, school and class; up to four parents or guardians with their mobiles; branch, course and batch; admission numbers such as AAK-26-0042; and documents such as marksheets, uploaded as PDF, JPG or PNG.

Courses, batches and timetable

Courses with subjects and a standard fee; batches with a branch, a teacher in charge, a room and a capacity that stops admissions when full; a weekly timetable by batch or by teacher that refuses a class clashing with the same batch, teacher or room.

Fees

Fee plans from the course fee, with scholarship, sibling, early-bird or staff-ward discounts and their reason; instalments made in one click and editable; receipts numbered per financial year on your letterhead, A5 or A4, with the GST inside the fee shown when you charge it; cash, UPI, card, bank transfer or cheque; refunds with their own numbers.

Dues

Overdue and due-this-week lists by branch and batch with how long each has been overdue, and a one-tap WhatsApp reminder to the parent that includes your UPI ID, with the date it was last sent.

Attendance

A batch's register on a phone: everyone starts present, tap the absent ones and save. Each student's attendance percentage, the absent students' parents one tap away, and a list of students below your attendance line with a WhatsApp message to the guardian.

Tests and report cards

Tests per batch with any subjects and maximum marks, a marks grid that takes AB for absent and negative marking, ranks with ties (1, 2, 2, 4), subject averages and a printable report card per student with every test, rank, class average and attendance.

Online tests

Students take a test on their phone or computer from one link, signing in with their admission number and an exam PIN. Six question types: MCQ with one correct option, multi-correct with partial marks, true or false, numerical with an allowed margin, short answers, and written answers such as 150–200 words with a live word count, marked by the teacher. Negative marking, pictures in questions, and questions and options shuffled per student. Anti-cheating: full screen, leaving the test is counted and can submit it automatically, copy and paste blocked, the student's name watermarked, one device per student. A live view for the teacher, a marking queue for written answers, and results that go straight into ranks and report cards.

Family page

A read-only page per student behind a private link you send on WhatsApp: attendance, fee instalments and receipts, and test marks with rank. It shows no address, phone numbers or notes, and you can switch it off at any time.

Announcements

Write a notice once for a batch, then send it to every family on WhatsApp with one tap each and a progress bar, or copy it into a broadcast list.

Dashboard and reports

Enquiries this month and the conversion rate, fees collected against what fell due, overdue fees, today's attendance, classes today and upcoming tests; fee collection by day, branch and payment mode; enquiries by source; attendance by batch; CSV for your accountant.

Team

Roles for Owner, Admin (optionally limited to one branch), Counsellor, Teacher and Accounts. Teachers see only their own batches and never fees; counsellors take fees but cannot refund; accounts see money, not marks or personal details.

Security

Students' and guardians' addresses, Aadhaar last 4 digits, notes, discount reasons, your bank account number, and student photos and documents encrypted with AES-256-GCM · passwords hashed with bcrypt · role checks on the server for every page and action, so a teacher only reaches their own batches · family links you can switch off · exam PINs encrypted and online-test answer keys kept on the server · login lockout · security headers · audit log · optional encrypted backups · 29 automated security tests.

Tested: 41 automated tests on instalment schedules, dues and overdue, receipt numbering, GST inside fees, attendance percentages, ranks with ties, timetable clashes and the marking of every online question type; an end-to-end test of the whole path from enquiry to admission, fee plan, receipt, refund, attendance, marks, report card, family link and announcement, plus first-run setup; end-to-end tests of an online test from writing the questions to a student taking it, the anti-cheating checks, one device per student, marking and published results; a check of every main screen for every role on desktop and phone; and 29 security tests.
