One File · Powerful fitness tracker
Every kilometre.
Every shoe.
A running log in one HTML file. Distance, time, type, shoe, route, effort, weather — and a shoe-mileage retirement banner that warns when a pair's about to wear out and start hurting your knees.
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 runners keep mileage logs.
Mileage adds up; recovery doesn't.
Shoe mileage is injury prevention.
Most worn-out trainers cause niggles you blame on the run. The shoe-mileage card warns at 70%; you swap before the IT band complains.
Type-mix tells you whether you're balanced.
Easy / tempo / intervals / long. The donut shows whether you're actually running easy on easy days, or junking it.
Yearly km against a goal is honest.
1000km this year? 1500? The tier card tracks against the goal you set. No public leaderboards.
Notes capture the why, not just the what.
'Felt strong, splits negative' — the line that tells you what the watch can't.

The promise
Your miles are yours.
Not a fitness social network'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 import from my watch?+
Not directly — type the distance and time. Most runners find the act of logging by hand makes the data more reflective; the watch already has the GPS trace.
Can I log multiple shoes per run?+
v1 supports one shoe per run, the most common case. If demand is real we'll add multiple.
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 morning's run.
