One File · Powerful fitness tracker
Every product.
Every routine. Every reaction.
A skincare log in one HTML file. Products, routines, reactions — with the unique trick: a shelf-expiry banner that surfaces actives 60 days before they go off.
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 people end up with routine logs.
Skincare is mostly waiting; the log makes the waiting honest.
Shelf-expiry banner is overlooked.
Vitamin C oxidises in months. SPFs lose UV protection. Tret stays good. The dashboard surfaces 60-day expiries so you replace before efficacy drops.
Active ingredients in rotation reveal the stack.
Niacinamide × 3 products, salicylic acid × 1, tretinoin × 1. After a year the dashboard reveals what your routine actually does.
Reactions correlate with actives over time.
Stinging on PM only? Probably the BHA. Redness only when it gets cold? The log isolates causes that memory can't.
Skin-feel trend is honest growth.
30-day average rating crawls up over months. The line that tells you the routine is actually working.

The promise
Your skin is yours.
Not a brand's training set.
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 scan ingredient lists?+
No — that's an OCR + database service. Type the actives as tags; ten products in fifteen minutes upfront.
Can I track Rx prescriptions?+
Yes. Tretinoin, hydroquinone, etc. all fit the retinoid / actives categories. Notes textarea preserves dose details.
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 routine that builds.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, log tonight's PM.
14-day refund · No subscription
