One File · Powerful fitness tracker
Every send.
Every project.
A climbing log in one HTML file. Every session, every ascent, every grade — and a grade pyramid that shows you what you can confidently climb plus the next stretch grade above it.
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 climbers keep notebooks.
Grade is a moving target; the log keeps it honest.
Working level is data, not feeling.
Three sends at a grade is a working level. The pyramid tells you objectively, not your gut after a strong day.
Beta evaporates by next session.
The crux on the V5 — was that left-hand crimp, right-foot smear? Notes per ascent save the beta.
Active projects ranked by attempts.
Six attempts on Yellow #14, two on the V6 traverse. The list tells you which one's overdue.
Indoor + outdoor in one log.
Discipline + grade scale per ascent — boulder V/Font + sport French + trad — without separate apps.
indoor + outdoor across 6 months
real grade distribution V0–V7
no recurring fee, ever
no signal at the crag; the log works

The promise
Your sends are yours.
Not a leaderboard's.
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.
Does it support route grades (sport / trad)?+
Yes. The discipline field per ascent is first-class — boulder grade V/Font for boulders, sport / trad with French / UK grades. The grade pyramid splits cleanly.
Can I track multiple gyms / crags?+
Yes. The 'where' field is free-text; the dashboard surfaces top venues by frequency naturally.
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 logbook that compounds.
We'll personalise a copy and email you a private link. Bookmark it, install it, log this evening's session.
