One File · Powerful productivity tracker
Every reference.
Every service.
A watch collection log in one HTML file. Refs, movements, accuracy in s/day, service intervals, and a rotation banner that flags pieces unworn 60+ days.
One payment · Yours forever · 14-day refund
- Works fully offline
- Installs as an app (PWA)
- No account, ever
- Yours, forever
Loads once, never needs the internet again. On a plane, in a basement, in a foreign hotel.
Every entry, every chart — stored locally. We never see it. We can't.
No subscription. No upgrades. No re-up next year. One file, yours.
Why log
Why collectors end up with watch books.
Service intervals and rotation patterns matter. Memory loses both.
Rotation banner keeps the box alive.
Pieces unworn 60+ days get flagged. The collection stays a collection, not a graveyard. Wind it.
Service intervals are real money.
Five years between services for most automatics. The dashboard tracks last-service vs. interval, surfaces approaches before they're overdue.
Accuracy s/day is for the obsessive.
Track daily-rate and you'll know when the next regulation is due. COSC tolerance for the mid-century pieces, ATC for the moderns.
Box-value tier card is quiet pride.
Sums market across the collection. Starter / Enthusiast / Collector / Connoisseur / Vault.
Rolex / Omega / Tudor / Grand Seiko / IWC / Cartier / GShock
real rotation across 6 months
no recurring fee, ever

The promise
Your box is your business.
Not a public flex.
Offline, always
Open it once, never need the internet again. The file holds the whole app.
Local-first storage
Every entry stored in your browser, on your device. No server sync. No leaks. Nothing to breach.
One payment, forever
No subscription, no upgrade tier, no nag. If we shut down OneFileClub tomorrow, your file keeps working.
Data does not sync automatically between phone and desktop
This is a local-first app — everything stays on the device you logged it on. To use it on both phone and desktop, use the built-in JSON or CSV export on one device and import on the other when you want to keep them in step.
Every view, light and dark.
A look at every screen across both themes — your tracker, populated.
Questions
Real answers, no fine print.
Can I track wear patterns by watch type?+
Yes. Per-wear occasion field categorises daily / formal / sport / travel. The most-worn list reveals real preferences.
Does it pull market prices?+
No — that needs Chrono24 / WatchCharts API access. Update market values manually quarterly; the trade-off is total privacy and £0/mo.
Where is my data stored?+
Locally, in your browser, on your device. Nothing is sent to OneFileClub or anyone else — there is no account, no cloud sync, no analytics.
Does it work offline?+
Yes. Once your personalised copy loads the first time, the entire tracker runs from a single HTML file. Airplane mode is fine.
What does 'personalised copy' mean?+
When you buy, OneFileClub stamps a private copy with your licence and deploys it to a unique URL just for you. You bookmark it, install it as an app, or save the file — and the file is yours, even if OneFileClub disappears tomorrow.
What is your refund policy?+
14 days, no questions asked. Email us, we'll process it and disable your private URL.
One payment.
A box that stays organised.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, log today's wrist.
