One File · Powerful productivity tracker
Every set.
Every brick. Every chase.
A LEGO collection log in one HTML file. Sets, minifigures, build hours — with market vs. cost-basis appreciation tracking. For the AFOL who knows a sealed Eiffel Tower will outpace inflation.
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 track
Why AFOLs end up with logs.
A collection without a database is just a pile of boxes.
Sealed sets appreciate quietly.
The dashboard banner surfaces market vs. cost basis with a delta. Eiffel Tower at RRP today, +30% in three years if held sealed.
Display location is real-world useful.
Where each set sits — living room, office, loft. Saves the 'where did I put...' the moment you have 20+ sets.
Pieces tier card is satisfying.
Total bricks across the collection runs as a number. Quiet pride.
Minifigures often outvalue the set.
Comic-Con Vader · Rare Yoda · UCS Han Solo. The minifigure entity is first-class because the rarity matters.

The promise
Your bricks are yours.
Not a marketplace'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 auto-pull market prices from BrickLink?+
No — that's an API integration. Update quarterly using the BrickLink price guide; the trade-off is privacy and £0/mo.
Can I track minifigures separately?+
Yes. The minifigure entity stores rarity, value, and which set it came from. Often the chase is the figure, not the set.
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 vault that compounds.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, log the next build.
