Leave Manager App

Leave Manager is an offline app (one HTML file in a zip) for UAE companies that still track leave in WhatsApp messages, paper forms or a spreadsheet someone recalculates by hand. You enter your leave rules once as settings, add your people, and the app counts the days, keeps a balance per employee, runs approvals and shows who is off on a team calendar.

The problem it removes: the monthly argument over "how many days does she have left?" and two people in one team being off together by surprise. Counting leave by hand across weekends, public holidays, half days and a mid-year joining date is slow and easy to get wrong.

What is inside:

• Requests with approve, reject and cancel, a decision note, and an overlap check (a morning half and an afternoon half on the same day are allowed)
• Balances per employee and leave type to any date: entitlement, carried forward, accrued to date, approved, pending, balance now, left for the year
• Entitlement and accrual as settings: monthly accrual by completed month or whole entitlement upfront, rounding, a carry-forward cap, a leave year starting on the 1st of any month
• Leave types you define: paid or unpaid, a yearly limit or none, working days or calendar days
• A public-holiday list you type or import; weekend days you choose (Saturday and Sunday, Friday and Saturday, one day, any pattern)
• A team calendar by month with a count of who is off each day, department filter and print
• A printable A4 leave record per employee (or all, one page each) with balances, leave taken and signature lines
• CSV import of people (name, department, join_date as DD/MM/YYYY) and holidays with a preview and line-numbered errors; CSV export of requests and balances
• Example data, example CSV files (one with deliberate errors), JSON backup and restore, Clear everything

Rules are settings, not built in. A fresh install leaves entitlements blank and says so. The example data shows 22 days of annual leave and 5 days of compassionate leave as example values only. Check the real entitlements, accrual, carry-over and sick-leave rules for your case with MOHRE, your PRO or your lawyer.

Who it is for: owners, HR officers and office managers of companies from about 5 to a few hundred staff who want a clear leave record without buying an HR system.

What it is NOT: legal advice, a payroll tool, or connected to any government system. It sends no reminders, does not calculate leave pay or end-of-service amounts, and the leave year starts on the 1st of a month, not on each person's anniversary. Sick leave is tracked by days only. The Employee Leave and Absence Tracker is an Excel workbook with absence-pattern scoring; this is a separate offline app with approvals, accrual by completed month, validation, imports, a calendar and printable records.

Your data stays on this device in your browser. Back it up with Export; clearing browser data loses it otherwise.

Verified by us: scripted browser tests in Chromium (36 checks through the real screens: leap-day joiners, month ends, DD/MM/YYYY parsing, two weekend patterns, a changed leave year, overlaps, half days, approvals, CSV import with errors, backup and restore, print preview and PDF output) and an independent Python (datetime and Decimal) recalculation of 80 balance rows from 40 random cases, zero mismatches. The test also passed in WebKit (35 checks, PDF step skipped). Firefox could not be launched in our test environment, so it is untested. Not tested on a real phone, in Edge or in desktop Safari; layout was checked at 375 px and 1280 px.
