Gym Membership Renewal, Freeze and Expiry Tracker with Door Check

Gym Membership Renewal, Freeze and Expiry Tracker is an offline app (one HTML file in a zip) for the front desk of a gym or fitness studio. You set up your plans, enter each membership with the start date and what was paid, record freezes, and log check-ins. The app works out the last day, the status of every member and the money still owed.

The problem it removes: Memberships lapse and nobody calls the member in time, so the revenue is lost quietly. A freeze is promised on a chat and the end date is never moved, or a member freezes for longer than your rule allows. People walk in on an expired card because the front desk cannot see the end date. This app puts the last day and the status beside every name.

What is inside:

• Plans with months, price and the most freeze days you allow, and memberships with start date, discount, payment and what is still owed
• Last day per membership: start date plus the plan months, minus one day, plus every freeze day recorded
• Freeze records with a rule that stops overlapping freezes and more days than the plan allows
• Member status: Active, Expiring soon, Expired, Frozen or No membership, with days left
• Renewals page: expiring soon, expired recently and not seen lately, each with a WhatsApp message, plus the renewal rate of memberships that ended in the last 90 days
• Door check: a check-in is refused if no membership covers that date or the member was frozen, unless the owner box is ticked
• Printable membership receipt, member card and call sheet
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: gym managers, fitness studio owners and front desk staff who sell monthly and longer memberships and track end dates in a notebook, a chat or a spreadsheet that nobody keeps current.

What it is NOT: It does not read membership cards, open doors, take card payments or send messages by itself. It does not know your freeze policy: you enter the maximum freeze days per plan. It stores no health or medical information. It is a membership record, not a class booking system. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (175 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 1285 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
