One File · Powerful fitness tracker
Patterns
over moments.
A mood and symptom journal in one HTML file. Daily mood, energy, anxiety, symptom chips, possible triggers — and a trigger-correlation insight that flags what tends to co-occur with low-mood days.
One payment · Yours forever · 14-day refund
- Works fully offline

- 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 mood journals.
One bad day is noise; six weeks of data is signal.
Memory rewrites bad weeks.
Last month felt awful — except it had three good days in it. Daily logging makes the actual shape visible.
Trigger correlation is the unique insight.
Caffeine on low-mood days more often than chance? Stress? Poor sleep? The list ranks what actually shows up — useful for clinicians, life decisions, both.
Heatmap is honest in a way you'd never voluntarily be.
24 weeks of mood at a glance. Patterns by season, by week, by month emerge whether you want them to or not.
Stealth mode for shared phones.
Blur entries until tap. Useful in public, useful with kids, useful if your mental health is private.

The promise
Your mental health is yours.
Not an insurer's risk model.
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 this a substitute for therapy?+
No. The journal captures the data and surfaces patterns — it doesn't diagnose, treat, or replace a clinician. Most users find it useful exactly because they bring it to a real human.
Can I print or export for a clinician?+
Yes. JSON or CSV export at any time. The trigger correlation list is the most-shared piece in the catalogue, anecdotally.
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 pattern that builds.
We'll personalise a copy and email you a private link. Bookmark it, install it, log today before bed.
