One File · Powerful productivity tracker
Build habits.
Don't miss twice.
A calm habit tracker in one HTML file. No notification nags, no friend leaderboards, no premium tier behind the year-view grid. Just your habits, your streaks, and a quiet record of who you've been.
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 a habit tracker beats willpower.
Showing up isn't a feeling. It's a check-mark.
Streaks reduce decisions.
Most days, you don't decide to do the thing — you keep the streak. The decision is the hard part; the streak removes it.
Don't miss twice.
One missed day is a slip. Two is a habit you've quit. The 'don't miss twice' rule is enforceable when you can see the calendar.
Quiet beats gamified.
No badges. No friend feed. No streak-saver guilt-trip you have to pay to skip. Just the calendar, populated by you.
Year-in-review beats year-in-app.
The year grid is a self-portrait. Print it, share it, archive it. It's yours either way.

Live insight banner
The single number that matters today, computed in real time from your entries.
Streak calendar
Daily streak across the last weeks. Showing up becomes the default.
Searchable, sortable list
Every entry findable in seconds — search across notes, sort by anything.
Free-form notes
A textarea per entry for the things that don't fit a field.
PNG share cards
One-tap share card of your stats, ready for Instagram or a group chat.

The promise
Your habits are quietly yours.
Not a leaderboard.
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.
What about reminders?+
Browser notifications work if you enable them — but the tracker doesn't nag by default. Most people check in once a day; the calendar is the reminder.
Can I share my year grid?+
Yes. The Share Card button generates a 1080×1920 PNG of your year for the social moment.
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 streak that's actually yours.
We'll personalise a copy and email you a private link. Bookmark it, install it as an app, check in tomorrow.
