Every focal length.
Every aperture. Every gap.

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 photographers track focal coverage.
The lens you don't have is the photo you can't take.
Coverage banner reveals gaps.
Buckets every lens 8-14, 14-24, 24-35, 35-50, 50-85, 85-135, 135-200, 200-400, 400+ — surfaces empty buckets. The next purchase becomes informed.
Multi-mount support for system jumpers.
Leica M + Canon RF + Sony E + Hasselblad — four systems in one file. By-mount donut keeps each clean.
Daily-driver flag captures the 80% you actually use.
Most photographers shoot 3 lenses 80% of the time. The flag surfaces them.
Library value tier card runs as you buy / sell.
Useful for insurance, useful for portfolio decisions.

The promise
Your kit is your business.
Not a marketplace's lead-gen.
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.
Vintage / rangefinder / TLR lenses?+
Yes. Mount field includes M39 / screw / Hasselblad / other / vintage. Filter thread + weight too.
Pairs with the photography log?+
Yes — runs alongside the camera-photography tracker. Bodies live there; lenses live here.
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 library that maps the kit.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, log the next acquisition.
