One File · Powerful productivity tracker

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 family heritage keeps writing itself.
Without a record, the family lore disappears in a generation.
Tree-banner counts generations + oldest birth.
5 generations documented, oldest born 1894 — 132 years ago. The depth is real.
Stories textarea is the heart of the file.
What grandfather did in the war. The route grandmother walked from Punjab. What's passed down. Captured in plain text, surviving every platform.
Heritage / ethnicity tags reveal the mix.
Punjabi-Welsh-Polish-Jewish in one tree. The donut shows what runs through the family.
Longest-lived ancestors top list captures something quiet.
94 years for great-aunt Ada. 87 for grandfather. The numbers tell their own story.

The promise
Your family's data is yours.
Not a public 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.
Auto-build the tree?+
No — that needs DNA + cloud. The trade-off is total privacy. Type relationships per person; the tree builds via 'parents' and 'children' name fields.
Pass it down?+
Yes — JSON / CSV export. The file becomes the heirloom. Children inherit a working file, not a dead login.
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 heritage file that lasts.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, write down what mum told you about grandad.
