One File · Powerful food tracker
Find your ratio.
Every brew, recorded.
Every brew, every dial-in, every small adjustment — in one HTML file you own forever. For people who actually weigh their dose and time their shots, and have noticed that without a record, every Tuesday morning starts from scratch.
One payment · Yours forever · 14-day refund

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 baristas write things down.
Coffee is a sequence of small variables. Without a record, every morning is guesswork.
Yesterday's perfect shot is today's mystery.
What grind setting was that? 12, 12.5, 13? Without a log, the next dial-in starts from zero. With one, it starts from yesterday.
The bag changes; you should know how.
New bag, same dial-in — usually wrong. The log shows you which beans needed coarser, which finer.
Trends beat tastes.
Every brew tastes good or bad in the moment. The 14-day score trend tells you whether you're actually getting better or just having a good week.
Top-beans-by-score is a shopping list.
After 30 brews, the topList shows you which beans are worth re-ordering. Stop buying the ones that average 5/10.

The promise
Your dial-in notes are yours.
Not a social feed.
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 multiple grinders / machines?+
v1 doesn't have a dedicated equipment field — most people note it in the brew notes. If demand is there we'll add it.
Will it work for filter-only setups?+
Yes. Espresso vs. brewed methods are first-class — the dose/yield/time fields adapt.
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.
Every Tuesday morning, dialled.
We'll personalise a copy and email you a private link. Bookmark it, install it, log this morning's brew.
