One File · Powerful productivity tracker
Every item.
Every session. Every round.
A personal inventory log in one HTML file — encrypted-on-device records of items, consumables, sessions, and maintenance. For the collector who wants total privacy and zero cloud.
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 serious collectors keep their own records.
An inventory file you control beats a cloud account that doesn't.
Privacy is the whole point.
No account, no cloud, no shared registry. The file is on your device, period. Stealth mode blurs item details until you tap.
Stock banner means no run-outs.
As you log usage, the dashboard surfaces low-on-hand consumables. Re-stock before the next session, not after.
Maintenance schedules compound.
Cleaning, lubing, repairs — every entry timestamps a record that survives the company shutting down.
Multi-purpose by design.
Categories include firearms, optics, edged tools, accessories, other — useful for any serialised collection where privacy matters.

The single number that matters today, computed in real time from your entries.
Tier progression
Lifetime totals roll into satisfying tier badges as you log.

The promise
Your inventory is your inventory.
Not anyone's database.
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.
Is the data encrypted?+
Yes. Optional encrypted backup uses AES-GCM with PBKDF2-100k. Your default storage is your browser — pick a strong device passcode.
Can I print or export?+
Yes. JSON or CSV export at any time. Paper printout from the browser preserves serial numbers and acquired-on dates for personal records.
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.
Total privacy, total record.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, take it offline forever.
