- 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 competitive MTG players track matches.
The matchup matrix is the deck-tuning tool no algorithm gives you.
Win-rate by deck (≥5 matches threshold).
Below 5 matches, win-rate means nothing. The dashboard hides anything thinner so the data means something.
Matchup matrix vs. archetype.
Mono-Red 70%, Yuriko 30%, Boros Burn 55%. The pattern reveals what your deck actually beats and what beats it.
Decklist preserved as text.
Even if your physical cards walk, the 60 or 100 list is in the file. Useful for tournament copy/paste.
Format + power-level fields organise the shelf.
cEDH (10), high-power (9), tuned (7-8), kitchen-table (4-6). The dashboard separates them.

The promise
Your match record is yours.
Not a public profile.
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 decklists from Moxfield?+
Paste plain text into the decklist textarea. Format: 60 / 100 with sideboard. Searchable across decks.
Suggests sideboard?+
No — that's craft. The matchup matrix shows you who beats you; the sideboarding is your call.
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 for the spike.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, log Friday's matches.
